Items are an integral part of gameplay in The Binding of Isaac. They modify a character's stats, grant or modify abilities, among many other things. There are 198 different items in the game. Below is a list of all of the items, separated into categories. Certain items change the appearance of your character when they are acquired. Items you've found can be seen in the Collection page. Click here if yout want to see the WotL Collection.

Caution - Please remember that the game saves on a timer, and also saves when you use the in-game exit command. It is possible to lose unlocked items, bosses, statistics and so on if the program is improperly closed without a chance to save.

Note: Please keep discussion of what items are better than what out of the tables. Use the Item Discussion page for that.

Item Demonstrations

Videos of items in use can be found by clicking on the Movie striplink in the info section for that particular item. Note that these are external links and will navigate away from the wiki.

Acquiring Items

The main ways of obtaining items are by entering Treasure Rooms and defeating Bosses. Items can also be purchased from Shops, found from Beggars, obtained by making deals with the devil, found in a Secret Room, dropped by standard enemies, and collected through other, less evident means, such as blowing up a Tinted Rock or opening a golden chest. It is possible to acquire activated/collectible items in the Challenge and "I AM ERROR" rooms. There are also five specific items you can get in the Arcade: Skatole from the shell game, either the blood bag or the IV Bag from the Blood Donation Machine, and either The Dollar from the Slot Machine or Crystal Ball from the Fortune Teller Machine, whichever happens to be in the arcade

Note 2: It is possible to "pick up" an item you didn't intend in the Boss Room with the trapdoor. If you have a high speed and walk into the trapdoor in the direction of the item, you will show as dropping into the trapdoor but your familiars will fly on ahead as if you were still moving. If they come near the item, it's possible it may get picked up.

Note 3: All characters (except for Isaac, until the D6 is unlocked) will start out with items.

Activated Items

Main article: Activated Items

These items are stored in the Spacebar slot and are used up once the button is pressed. The items then recharge in one of two ways. Normally, they charge a number of bars after every room you clear -- some items charge one bar at a time, others charge faster. Note that only rooms where the doors close until they are cleared count -- Bosses, arenas, enemy rooms, etc. The Collectible Item "Battery" can give bars of charge during combat, on top of the normal recharge. Another Collectible Item, the "9 Volt" will automatically recharge 2 bars when an item is used; this effectively reduces the number of rooms required to charge an item if the item requires 3 or more rooms to charge. In the Wrath of the Lamb DLC, there is another item, the Habit, which will recharge bars when taking damage. To see a clearer version of the in-game arrangement go to the Collection page.

Note: You can only hold one of these at a time.

Additional Note: Any two of the same activated item on the same floor will share charge state, i.e. finding another of the same activated item' when one is not fully charged' will not give the player another fully charged version of the item.

Item Effect Info Rooms to Recharge Collection Grid

(Pg, X, -Y)

Anarchist Cookbook

File:Anarchist cookbook.png

Spawns six troll bombs around the room.

Frequently dropped by Pride.

The Tower tarot card has the same effect.



The Bean


Causes the player to have bad gas, damaging and poisoning any enemy in close vicinity.

(Same as the Bad Gas pill)

Unlocked by destroying 50 poop piles.

Movie strip



Bob's Rotten Head

File:Bob head.png

Throws a bomb in the direction Isaac's facing. It does extreme damage, poisons the enemy for 5 seconds, and destroys rocks. Bombs will arc back towards Isaac with the My Reflection upgrade.

Isaac can be damaged by the explosion if he is within the blast radius (though he cannot be poisoned).

Bug: Having Brimstone and attempting to use Bob's Rotten Head causes you to get stuck.

Bug: Dealing poison damage to War while off screen causes him to get stuck in the walls.

Bug: Having Technology 2 renders you unable to throw Bob's Rotten Head.

Sloth and Pestilence are highly resistant to the blast and immune to the poison. Appears in secret rooms or as a drop from Sloth.



The Bible

File:The Bible.png

Transforms the player into an angel, allowing him or her to fly over obstacles for the current room only.

Isaac Fate

Instantly kills Mom, Mom's Heart, and It Lives.

Satan or Isaac will instantly kill you for using it, even after death (unless you have The Wafer).



The Book Of Belial


Doubles damage until you exit the room, just like The Devil tarot card. It also gives Isaac an angry face with empty eye sockets with blood running down his face until he exits the room.


Unlocked by beating the full game. Can rarely be found in secret rooms and the devil room, as well as in the library. Judas starts the game with this item.

Movie strip



Book Of Revelations


Adds 1 Soul Heart.

Using the book will ensure you meet a Harbinger as the level boss, if possible.

May also cause you to fight the Headless Horseman in Sheol instead of the final battle with Satan.

This item is most commonly found in shops, but it can also be found in the library, devil room or even in the item room. It's also a rare drop by the beggar.



Book Of Shadows

File:Book of Shadows.png

Grants invulnerability for 12 seconds. Will start flickering before stopping.


(Fixed) Greed, Avarice and Hangman still knock out your coins if you get hit by shots fired by them.

This cannot be used to get items from the devil room without paying.

You can farm Blood Donation Machines and Devil Beggars for free while this item is activated.

This item can be found in the library, the item room and the shop.

Trivia: This book is a reference to the book used by the witch sisters in the TV series Charmed'.

Movie strip



The Book Of Sin


Spawns a random pick-up, pill or tarot card.

Unlocked by beating each of the Seven Deadly Sins.

Can be obtained in the devil room.



Dead Sea Scrolls


Uses a random Activated Item (even locked ones).

If the item mimicked has no recharge time (Kamikaze! for example), the scrolls can be used again immediately with no recharge period.

Beware; this item may harm the player if the effect mimicked can do so.

Sometimes causes zombies to "moonwalk" when used.

Movie strip



Deck of Cards


Gives the player a random tarot card.

The card spawns in the player's inventory. This will cause the player to drop the currently held Q - slot item when used.



The Dice


Re-roll all activated and collectable items on screen.

It can also be used to change shop merchandise or boss drops. The exception is with special drops from alternative bosses, like Cube of Meat from the Horsemen or Little C.H.A.D. from C.H.A.D., which will simply replace them with the same item.

The D6 re-rolls items from the same pool, eg. a secret room reroll will only yield another secret room item.

It is possible to obtain items only unlockable through achievements using the D6 without having completed the achievement.

Bug: It is possible to exploit this nature to obtain 2 Cubes of Meat from 1 Horseman. Using The D6 while a Cube of Meat is onscreen can change other items, such as a Small Rock or an item from a Beggar spawned with XX Judgement, to turn into '''''Cubes of Meat (for example, here are 3 cubes on one screen).

Bug: There is a small chance that the new item will be undefined. See the bugs section for more information.

Unlocked by completing The Womb with ???.

After being unlocked, Isaac starts the game with this item.



Doctor's Remote


Sets a big red target on the ground which can be controlled with the arrow keys. After several seconds, a huge explosive missile hits it.

Pressing space at any time during the targetting phase will launch the missile at the target.

Trivia: This item is a reference to an item used by Dr. Fetus from Super Meat Boy.

The missile acts like a huge bomb explosion.



Forget Me Now


When activated, the level ends and is freshly regenerated with new rooms, monsters, and items. Disappears after use.

Using this effectively forces you to abandon your current Activated Item.

This item is a reference to Arrested Development, where 'the character Gob calls "roofies" Forget Me Now.

Unlocked by completing Sheol with ???.



The Gamekid


The user turns into a Pac-man-like creature, gaining invincibility, the ability to damage enemies on touch, and causes enemies to run away for 5 seconds. Heals 1/2 heart for every 2 enemies killed while in use.


Health leech will not work on bosses unless delivering the killing blow - it will however work on monsters spawned by bosses, granting soul hearts instead.

The health leech also does not work with ???.

There is a bug when using the Gamekid with Technology. The controls will be inverted for the left and right fire until you leave the room. It will also sometimes visibly move your head until you leave the room. (Probably in combination with Technology, but not confirmed.)

Does not work on the Masks of Evil enemy, even while chomping the hearts. (bug?)

When used in the Devil room, the Heart colors appear darker, but these are NOT turned to soul hearts (buying an item will cost normal hearts).

This item icon is a reference to the Nintendo Gameboy, one of the first portable gaming systems, the transformation a reference to Pac-Man.

Unlocked by visiting arcades 10 times.

Movie strip



The Hourglass


Slows enemies and enemy projectiles for 7.5 seconds.

Bug: When this item is used on bosses that fire exploding arced shots (Sloth, Pestilence, etc.), twice the normal amount of the shots are fired.

If used while The Fallen copies himself, The Fallen becomes 4, instead of 2

Movie strip





Causes an explosion in the same area as Isaac, causing one heart of damage, but also damaging monsters caught in the blast.


Unlike Blood Donation Machines, this will use up your Soul Hearts as well. Affected by The Wafer's damage resistance.

Can be used multiple times without losing any hearts while under the invincibility effects of the Chariot card.

This does not count towards "take no damage" achievements.

Movie strip



Lemon Mishap


Causes the player to have an accident, creating a pool which damages anything that crosses it (except for the player).

Flying enemies are not damaged by the pool.

Similar to Peep's ability.

Movie strip



Mom's Bottle of Pills

File:Mom's Bottle of Pills.png

Spawns a random pill near the player.

A player will only receive six different pill types in one playthrough.

The pill spawns in the player's inventory. This will cause the player to drop the currently held Q - slot item when used.

Unlocked by using a Blood Donation Machine 20 times.

Movie strip



Mom's Bra


Causes the player to wear the bra for a short period of time and freezes enemies for the next 5 seconds.


If used on Mr. Maw, the usual Maw will appear after the freeze effect ends.

Bug: If this item is used on Satan it may cause a bug that makes winning impossible. See the bugs section.

Bug: If used on Fistula, this can cause divisions of the boss to get stuck on rocks.



Mom's Pad

File:Moms pad.png

Causes enemies to back away from Isaac for 5 seconds.

Bug: If used against stationary bosses like Gurdy, they will slide away, but recenter after its duration ends.

Movie strip



Monster Manuel

File:Manuel IT.png

Summons a random familiar (even locked ones) for the current room only.

Trivia: This item's name and graphic are both references to the D&D Monster Manual.

Summoning "A Cube of Meat" will summon a random level of Meat Boy (1 through 4).

Unlocked by completing Sheol with Judas.



Monstro's Tooth

File:Monstros tooth.png

Monstro jumps onto a random enemy, doing damage.

Monstro can do damage to you if he lands on you or you walk into him. This cannot be used against Monstro.

Monstro can be damaged when he appears on screen and can be killed if you freeze him or he gets caught in Satan's laser attack, but drops nothing on death.

Note: Despite the fact that it can't be used on Monstro it can be used on Monstro II.

Bug: If used on War when he jumps up to drop Troll Bombs, he will become stuck and the player will be unable to do anything.

Unlocked by beating all bosses in The Basement.



Mr. Boom

File:Mr Bomb.png

Drops a large bomb.

It has an increased blast radius of 3 squares in contrast with the 2 squares of regular bombs.

Does not destroy doors like normal bombs.



My Little Unicorn

File:My Little Unicorn.png

Grants Isaac temporary invincibility while damaging enemies by touch.


Trivia: This item's name is a reference to "My Little Pony", a popular television show featuring unicorns and magic. Isaac won't fire unless he's holding Mom's Knife. Familiars will attack as normal..

Bug: You will still lose coins from touching Super Greed while this item is activated.

Bug: You can farm "Blood Donation Machines" for free while this item is activated.



The Nail


Turns Isaac's body black with twisted horns, adds one Soul Heart and allows the breaking of rocks by simply walking over them. Increases damage by 1 and decreases speed by 1. Also allows the breaking down of the Challenge Room door.

Ss (2012-07-04 at 05.37.38)

Unlocked by completing game 3 times. Available in the Devil Room (or as a possible drop from The Fallen). Also appears in the Curse Room and can be given by the Demon Beggar if you have the Wrath of the Lamb DLC.



The Necronomicon


Damages all enemies in the room significantly.

Unlocked by using the Death Tarot Card 4 times.

It will also destroy all enemy shots on the screen at the time you use it.



A Pony


While equipped, increases speed by 2 and allows Isaac to fly over rocks, pits, blood, and spikes.

Upon use Isaac will charge in the direction selected and deals damage to monsters.

Official pony

This is a possible reward from defeating the Headless Horseman (the other being the Cube of Meat).

The Pony is the only spacebar item with a passive effect while it is equipped. If it is replaced by another item, these bonuses are lost.

If spacebar is pressed but directional buttons are not, your character will become permanently invincible and will deal damage to all enemies that touch.

Can be used to hit the Blood Donation Machine without taking damage.



The Poop


Drops a pile of poop, exactly like the ones that litter the basement.

Will block enemies' movement and attacks.

As with regular poop, destroying it may yield coins or hearts.

Unlocked after 10th playthrough.

??? starts the game with this item.

A strategy for this item is to use it to block out enemies shots, since it will act as a shield.

When used while being on a spider web, poop does not appear.



Razor Blade

File:RaZoR IT.png

Deals a certain amount of damage to self, in exchange for increased damage in the current room.

Eve Razor Blade small

Eve before and after using the Razor Blade.

As with the Blood Donation Machine, this uses up your heart containers first before it takes your Soul Hearts.

Unlocked by completing The Womb by Eve.

Bug: Will cause death if it removes the last whole remaining heart container, even if Soul Hearts remain.



The Pinking Shears


Separates Isaac's head and body for a single room. Control is retained for his flying head while his decapitated body will automatically attack enemies in range dealing high damage (essentially a powered-up Meat Boy).


Unlocked by dying 100 times.

Found in Shops and the Item Room. Also spawned by The Dead Sea Scrolls.

When used in conjunction with Habit, it is possible to have multiple copies of Isaac's body all attacking enemies.

(If you are using an item that makes Isaac Black, such as Lord of the Pit, the body will also be Black.)



Shoop Da Whoop!

File:Shoop Da Whoop.png

Fires a laser from Isaac's mouth. Using the item charges the laser- it can then be fired in the chosen direction. The laser penetrates all obstacles and enemies in its path and can damage multiple enemies.


Trivia: This item is a reference to an internet meme of the same name originating from 4chan depicting a face similar to the icon firing a lazer.

This item can sometimes be dropped by Envy.



Tammy's Head


Shoots 10 projectiles in a circle around you.

Modifiers to your primary fire also modify the tears used for Tammy's Head as well (eg. Boomerang Shot, Homing Shot).

Charges after every room.

Tears do not turn into Brimstone lasers, Technology lasers, or Dr. Fetus bombs and will behave as any tears Isaac would fire should he not have any of the items mentioned.

More commonly found in Chests than anywhere else.

(Note: Tears fired by Tammy's Head do highly incresed/max damage.)





Teleports the player to a random room, including secret rooms and the boss room.

Can teleport to the I AM ERROR room, otherwise only accessible via Teleport or the consumption of Telepills. Chance of this happening varies between 5% and 10% per teleport, chance lowers as floors increase in number of rooms.

If Isaac teleports into the Devil Room before beating the boss, he will leave to the first room on the level. This potentially allows to skip Mom's Heart entirely.

Can also be used (along with other player moving items) to "reroll" champion bosses for a different version by use during the boss fight.

Movie strip



We Need To Go Deeper

File:We need to go deeper.png

Creates a trap door to go to the next level.

Using on Womb 2 creates a trap door to Sheol (even if Sheol has not been unlocked yet). Will not have an effect in Sheol.

Does not count for certain achievements that require going through an area without getting hurt if used in the second part of a level (Basement 2, Cave 2, Depth 2 and Wombs 2) because the second boss must be killed to unlock said achievement. Nevertheless, for these achievements, this item can be used in the first part of a level (Basement 1, Cave 1, Depth 1 and Wombs 1). proof link

This item appears in secret rooms or the devil room, and is a possible drop from The Fallen.

Cannot be used to skip from Cathedral to the Chest, even if you have the Polaroid.



Yum Heart

File:Yum heart.png

Restores 1 whole heart.

Unlocked by having seven heart containers.

Useless with "???"

Magdalene starts the game with this item.



Wrath of the Lamb Activated Items

The following activated items can only be acquired in the Wrath of the Lamb DLC.

Item Effect Info Rooms to Recharge Collection Grid


Best Friend

File:Best friend.png

Deploys a decoy Isaac that eventually explodes.

The explosion can hurt the player if they are within the blast radius.

High chance of getting eaten by Chub like regular bombs.

Orbiting items such as meat cube and sacrificial dagger will be transferred to the doll when activated.

If you have Distant Admiration, Forever Alone, or other type of follower fly when you use this item the flies will follow the decoy until it explodes.

Bug: If you activate Best Friend while you have the Sister Maggy familiar, Sister Maggy will turn into Ghost Baby until the decoy explodes, after which it will revert back to Sister Maggy immediately.

If you collect any three of the Guppy's items (Guppy's Head, Guppy's Tail, Guppy's Paw, Dead Cat), Isaac will becomes Guppy. If it's Guppy's Paw or Guppy's Head, you only need to use it once (you can drop it afterward) to make the game counts you as "carrying" the item.

1 (B,5,4)

Guppy's Paw

File:Guppys paw.png

Removes one Heart Container in echange for gaining 3 Soul Hearts.

Does nothing for ???.

These items generally give you some kind of a boost to your stats, or add a special passive ability. They take effect immediately once picked up, and continue for the rest of the game (except for several items that do not provide any lasting effect).

Edmund McMillen split them up in his blog into the subcategories weapon item, stat padding items, passive items, and familiars.

Item Effect Info Collection Grid

(Pg, X, -Y)



Increases available heart containers by 1 and restores all health.

Can be picked up multiple times in one playthrough.

Bug: Sister Maggy or Little Steve will turn into Brother Bobby until exiting the room.

Bug: Having a 1UP while doing a deadly trade with the devil, or dying at any other time when you have no normal heart containers, results in a rebirth with 0 hearts, unless Guppy was bought before.

Only appears in Secret Rooms.


Familiar: Follows the player.

Upon pickup, Isaac's current activated item will be fully charged.

This item is most common in shops.

File:Nine Volt Isaac.jpg

If used in conjunction with X-ray Vision  / Dr Fetus , this allows an infinite use of the activated item by running between uncompleted rooms and the secret room / blowing up the a door of an uncompleted room, running out and in again. Using The Book of Revelations or The Nail for example can provide unlimited Soul Hearts.

This item is most common in Shops and can be dropped by beggars.

No visual effect.

Movie strip


Bomb Bag

File:Bag of Bombs IT.png

The Character is followed by a small bag that drops a Bomb, 1+1 Free, or Troll Bomb upon completion of every 3 rooms.

Unlocked by completing Sheol with Cain.


Familiar: Follows the player.



File:Boom big.png

Gives 10 bombs.

Found in the Item Room or Challenge Rooms.

File:Boom! isaac.jpg

Adds a lit fuse to Isaac's head.




Increases HP by 1.

Found in the Boss Room and can be dropped by the Beggar.

No visual effect. (A,7,3)



Changes tears to a chargable laser that pierces all objects in its path be they rocks, poop or Knights . It can only be fired after a short charge-up period (approximately two seconds or until Isaac's head flashes red). The laser is channeled for about two seconds so it is possible to destroy some two-stage enemies in one shot (Globins and Hives along with the flies they spawn on death), or to strafe the shot over multiple enemies.

It is possible to charge before entering a room so that the first shot can be fired immediately. (for half its damage)

Note: another shot can be charged during the attack animation of the first. To attack at maximum speed, release to attack and then instantly start holding again to fire about a second after the first blast is done. As of v1.48, this appears to have been changed. If you begin charging Brimstone while firing, the shot will be cancelled.

Using it with Chocolate Milk allows the character to fire before completely charging the attack (doing less damage). Charging up a shot before entering a new room is pointless with this combo, since the attack will do no damage. Also, Chocolate Milk drastically reduces the overall damage of Brimstone, even when fully charged.

When used with The Innter Eye, it will cause Brimstone to charge 3 times slower, but also cause it to deal 3 times as much damage.

Mom's Knife will override this effect making this power-up useless.

Increasing your Tears stat reduces charge up time of Brimstone.

Increasing your damage stat does increase Brimstone's damage

Removes knockback effect of tears.

If you already have Technology and you pick up Brimstone, brimstone will override Technology.

If you already have Dr Fetus and you pick up Brimstone, brimstone will override Dr Fetus.

If you have Chocolate Milk and Brimstone at the same time, you can instantly fire a blast for a smaller amount of damage by just tapping/clicking the attack button.

Technology 2 still fires a laser if Brimstone was acquired after Technology 2. This may be a glitch, as the laser is thin, flickers and appears to go "backwards" a bit as well as forwards. It will still deal damage, however.

If you obtain technology 2 after brimstone, it will typically work the same as getting brimstone first, but without the flickering. The exception is when using Cain, in which case brimstone will cease to shoot and instead technology 2 will fire at all times and deal immense damage. (Needs confirmation for Cain)

For Cain, if Technology 2 was obtained first, the Brimstone laser will charge but not fire. There is also a delay created when attempting to turn. Technology 2 does damage as it normally would.

If you obtain Brimstone after getting the Dead Dove, Isaac will take the form of Lord of the Pit but shoot the Brimstone laser

Brimstone's charge (open mouthed laser) will overlap any item that is on the player's face, this is obviously a graphical bug.

As of 1.3, attempting to recharge the laser while it is firing will stop the laser, preventing it from firing or causing it to do less damage.

Available in Devil Room for 1 or 2 hearts or as a reward after fighting The Fallen.

Brimstone Isaac

Isaac appears demonic.


Brother Bobby


Follows the player around shooting normal tears.

Found in the Item Room or in the Devil Room. Can also be a reward from the Devil Beggar.

Brother Bobby

Familiar: Follows the player.

This item is rarely dropped by Gluttony. Can also be found in Item Rooms.


Isaac appears significantly fatter than usual.

Movie strip


Charm Of The Vampire

File:Charm of the Vampire .png

Killing 13 monsters heals the player for half a heart.

This can be used to the player's advantage when fighting Globins. Every time they get to the ooze form, it counts as a kill. Therefore, if Charm of the Vampire is present, one could get several hearts by shooting at Globins but not completely killing them, and when they revive, repeating the process.

Splitting apart Envy, Fistula, and The Fallen will count as one kill. Killing Flies does not increase the counter.

If the kill counter reaches 13 while at full hearts, the counter resets and the heal is wasted.

Useless to ???.

Charm of the Vampire

Issac gains a smirk and sports a widow's peak similar to that of the original Dracula, as well as vampiric fangs.


Chocolate Milk

File:Chocolate Milk.png

Allows the player to charge shots making them a lot stronger and larger, and turns them brown.

Increases the damage of Technology, firing speed of Spoon Bender, amplifies The Inner Eye after a slightly longer charge, and causes Mom's Knife to do increased damage. Allows Brimstone to be fired with a partial charge for less damage, but causes it to do no damage if you charge before entering a room and firing.

A good combination with Chocolate Milk is an auxiliary shooting familiar like Little Steve or Brother Bobby. This is because while you are charging up your shots, your auxiliary familiar will continue shooting. This can buy you time so you can fully charge up.

File:Choco milk.jpg

Cheeks inflate while shots are charged.


The Common Cold


Gives the player's shot a chance of poisoning enemies for 2.5 seconds and turns tears green.

The effect is retained when combined with Technology or Brimstone. The Technology laser will turn green, while the Brimstone laser will keep its original color.

Unlocked by collecting two of either Roid Rage, The Virus, Speed Ball, or Growth Hormones in one session.

Common Cold Isaac

Isaac gets sick. Instead of crying, Isaac will now spit green projectiles.



The Compass

File:The Compass.png

Shows the icons of special rooms (Item room, Boss room, the Shop, the Arcade, Mini-boss room) on the map without revealing rooms.

Does not reveal secret rooms. This will reveal if Greed is present by displaying a mini-boss icon with the shop icon.

Common in shops and occasionally found in Challenge Rooms. Available from the Beggar. Never found in Item Rooms.

No visual effect. (A,3,3)

Cube Of Meat


This item can stack and has different effects based on how many cubes have been collected.


The first pick up gives a floating cube similar to the Pretty Fly that damages enemies it touches and blocks projectiles.


The second pick up changes it into a floating head that still damages on touch and blocks projectiles, but now also spits blood shots.


The third pick up changes it into a humanoid Meat Boy, who walks around chasing enemies, but no longer shoots projectiles. On occasion, it will unintentionally shove items aside while following you or attacking enemies, including bombs.


The fourth pick up increases his size and damage. (He still shoves items.)

Collecting a 5th Cube of Meat will provide another floating cube (so in theory after collecting an 8th Cube of Meat, the player would have two lvl 4 Meat Boys. The bug where a 5th cube would create a "headless boy" instead was fixed, as seen in this video.)

Note: If you have more than two Pretty Flies, the Cube of Meat will circle Isaac where the third fly should be, though the fly will still be visible.

Bug: On the second pick up when entering a room it will turn into brother bobby for a split second

Unlocked by completing The Depths.

Meat Cube Isaac

Meat1boy > Meat2boy >

M3atboy > Meat4boy

{C}Level 1 - 2: Orbit: Circles around the player At level 2, it shoots blood.

Level 3 - 4: Familiar: Follows the player.


Cupid's Arrow


Gives the player piercing shots that will travel through and damage multiple enemies and cause damage to Knights from the front. Shots don't go through obstacles.

Removes knockback effect of tears.

If you have Parasite and Cupid's Arrow, tears will no longer split when they hit enemies.

Cupid&#039;s Arrow Isaac

Isaac wears a Native-American headdress.


Movie strip


Dead Bird

File:Dead Bird.png

Whenever Isaac takes damage, the bird starts attacking nearby enemies while flying over obstacles. The effect only lasts for the current room.

This item can be activated through self-damage.

Eve starts the game with this item.

File:Dead Bird Isaac.jpg

Familiar: Follows the player after activation.

Isaac: A small bird trinket is on Isaac's head.


Dead Cat

File:Dead Cat.png

Your HP is set to 1. You are followed by a floating cat head and have 9 lives (these still count as deaths on the statistics screen). You can increase your max HP as normal, but after each death it will reset to 1 again. (1 soul heart with ???)

Even if you have more than three heart containers, you will only have one heart container left once you purchase Guppy, since it sets your HP to 1 immediately, not after your first death. If you buy him for the price of 2 hearts from the devil and you have 2 or fewer hearts, you will acquire him, die, and respawn with 1 heart (therefore losing 1 of the extra lives. ???'s health will be set to soul heart. If you have no health at all you will get 1 heart container that is filled half). The cost of purchasing items in the Devil Room must be met, but if it would kill you, you will respawn.

Bug/Exploit: After defeating a boss, if you die after the item appears but before the boss disappears you will be able to fight the boss a second time for yet another item. (Pick up the item, then kill yourself with a bomb or something similar. You will then respawn outside the boss room with one less life on your counter. Going back inside the boss room allows you to now fight the boss again for another item. Can be done as long as you have additional lives on your counter. Can also be performed after picking up a 1UP.)

Guppy will sometimes appear as a collectable item as well as in the Devil room. Collecting more than one Guppy will not add any more lives if the player already has 9, but will reset your health back to 1.

When you get additional heart containers your heart containers will reset to 1 after your first death.


Familiar: Follows the player.




Increases available heart containers by 1.

Found in the Boss Room.

No visual effect. (A,6,3)



Increases available heart containers by 1.

Found in the Boss Room.

No visual effect. (A,5,3)

Distant Admiration


A red attack fly circles further out than the Halo of Flies/Pretty Flies, but closer than Forever Alone.

The attack fly can deal damage to all enemies, unlike the other flies which can only block shots and hurt enemy flies.

Deals more damage than Pretty Fly/Forever Alone.

Red Attack Fly

Orbit: Circles around the player.

Movie strip


Demon Baby

File:FFS Demon Baby.png

Follows you and automatically fires short range shots from any angle at enemies near you. Does not shoot if there are no enemies in the room or none in range. Does not shoot across holes in its range.

Confirmed to take on the effects of the player's own projectiles, like the Spider's Bite's slowing effect and Mom's Contacts' freeze effect.

Unlocked by completing Sheol with Eve.


Familiar: Follows the player.


A Dollar


Sets your penny counter to 99.

The A Dollar and Blood Bag rewards can be "rolled" with the D6.

A final reward from Slot Machines; they come out when the machine explodes from overuse (rarely).

Automatically unlocks Cain.

No visual effect. (A,9,2)

Dr Fetus

File:Fetus in a jar.png

Replaces the player's shot with a bomb. Only one bomb can be shot at a time, and it will slide a fixed range before exploding. The bomb slides over pits, and can be pushed around. Bombs detonate faster as the Tears stat increases.

With the Chocolate Milk, bombs will have a bigger blast radius when charged, but only in the room in which Chocolate Milk is collected. Once the player leaves that room, the bombs function normally again. This is likely a bug.

With the Ouija Board, Bombs will also slide through Rocks.

With The Common Cold, Bombs will add a poison effect.

With Mom's Contact or Parasite, bombs will be colored red.

If you have Dr Fetus and Technology at the same time, you will fire both a bomb and laser simultaneously.

Will NOT override Brimstone, but will BE overridden by it.

With Spider's Bite, bombs gain slowing effect and bombs will flash red and yellow.

In the Wrath Of The Lamb, when combined with Mr.Mega the bombs gains the huge troll bomb look.

Substantially increases the likelihood of bomb-related upgrades.

The Bobby-Bomb and Mr. Mega upgrades improve Dr. Fetus bombs as well.

Epic Fetus has priority over Fetus in a Jar.

Bug: After Globins collapse in a pile and then revive, the bombs will pass through them, making them much harder to hit.

The Common Cold makes the bombs fired green but no poison effect is added to the bombs.

Unlocked by completing the game 5 times.

A rare find in the Item Room and Shops.

When fired and shot at by Little Gish, the bombs will appear black and may slow any surviving enemies.

With the Lump Of Coal, the bombs turn completely black.

With the Parasite, the bombs turn reddish-brown.

File:Dr Fetus.jpg

Isaac sports the familiar top hat and monocle of Dr. Fetus from Super Meat Boy, another game made by Edmund McMillen.


Forever Alone

File:Forever Alone Fly.png

Spawns a blue attack fly that orbits a long distance from you.

Doesn't deal as much damage as Distant Admiration.

Blue Attack Fly

Orbit: Circles around the player.


Guardian Angel

File:Guardian Angel IT.png

Spawns a guardian angel that orbits the player. Does damage on touch similar to other orbitals.

This will also cause all orbiting items/familiars (Pretty Flies, the Cube of Meat, Distant Admiration, Forever Alone, and the Guardian Angel itself) to orbit at roughly double speed.

Trivia: The misspelling of 'Guardian' within the game ('Grauniad') is a reference to the British newspaper "The Guardian"'s tendency to make typographical errors, a joke popularized by 'Private Eye'.

Unlocked by completing Sheol with Maggy.

Found in the Item Room and Angel Room.

File:Guardian Angel.png

Orbit: Circles around the player.


Growth Hormones

Growth Hormones

Increase Speed and Damage by 2 each.

Bug: The growths remain pink when Isaac's body is turned into another color due to color-changing items.

File:Growth Hormones.jpg

Issac receives inhuman growths on his head.


The Halo


Increases all stats except range by one.

Unlocked by defeating either Mom or Mom's Heart by using The Bible.

Found most common in the Item Room.

File:Halo Isaac.jpg

Isaac sports a halo.

Movie strip


Halo Of Flies


Grants 2 Flies that circle the player, blocking enemy shots that hit them. These kill other flies that touch them but do not damage other enemies.

Can stack with a Pretty Fly/Cube of Meat/Guardian Angel/Itself up to a maximum of three. Flies have the lesser priority regarding orbitals and are replaced by other orbitals when all 3 "orbital slots" are taken. Flies cannot replace other orbitals and nothing happens if picked up when already having three.

Found in the Item Room.

File:Halo of flies.jpg

Orbit: Circles around the player.

Movie strip


The Inner Eye


Gives the player a triple shot, sets Tears to minimum (rate of fire).

If you have Technology, this will increase Damage to maximum and decrease firing speed to minimum.

If you have Brimstone, this will cause Isaac to fire a single beam that causes 3 times as much damage, but with an increased charge up time of 5 seconds.

It also negatively affects Dr Fetus bomb firing speed.

Chocolate Milk allows the triple shot to be fired more quickly for lower damage.

File:Inner Eye.jpg

Isaac gains a third eye.



The Ladder


Allows the player to walk across gaps one square across by automatically placing a ladder between the two walkable areas (or between walkable area and room wall).

It also confuses the pathfinding of all non-flying enemies. For example, Globins /Gapers will lose you and stop if you are standing over a gap. This is very useful against all non-shooting, non-flying monsters.

Note that this item is only useful in levels from 3 to 6 as later levels do not have pits.

Bugs: It is possible to get stuck if you use the ladder to walk onto a tile surrounded by pits with a shooting stone skull. One can also get stuck by quickly moving onto a tile with a skull statue surrounded by pits, as the player will be pushed and trapped between two of them.

This item is fairly common in Shops.

Isaac The Ladder Small

No visual effect on the character, but the ladder appears beneath them when crossing gaps.


Little C.H.A.D.


Drops a half Heart upon completion of every two rooms.

Useless to ???.

Bug: If the player already has Little Steve, Sister Maggy or Little Gish at the time of collecting Little C.H.A.D., Little Steve/Sister Maggy/Little Gish will be transformed into Brother Bobby for the duration of the room.

Unlocked by killing the alternate boss C.H.A.D.


Familiar: Follows the player.


Little Chubby

Little Chubby Icon

Adds a small grub that follows you.

Charges forward and deals touch damage to any enemies in his path. Will attack when the player attacks with a moderate cooldown time before he can attack again.

Chub's attack is affected by momentum, just as tears are. Thus, he can be shot diagonally.

Although Little Chubby has an enemy penetrating effect it will not damage Knights from the front like Cupid's Arrow or Technology will.

Note: When you enter a new room the first shot will automatically activate Little Chubby.

Unlocked by defeating all of the Caves bosses.


Familiar: Follows the player.


Little Gish

File:Little gish.png

Follows Isaac around shooting tar projectiles that reduce enemies' movement speed, shot speed, and range for 2.5 seconds.

Unlocked by killing the Gish alternate boss and is dropped after the boss fight.

Familiar: Follows the player. (A,9,10)

Little Steve


Follows Isaac around shooting homing projectiles

The D6 CAN be used after the boss fight with the alternate boss Steve to give Steven instead of Little Steve, and vice versa. However the drop rate of Steven from Steve is very low, re-rolling most likely gives you Little Steve again.

Unlocked by killing the Steve alternate boss and is dropped after the boss fight. Can also be found in item rooms.

Bug: Little Steve might turn into Brother Bobby in every new room until you get harmed.


Familiar: Follows the player.


Loki's Horns


Gives a random chance for projectiles to fire in a cross (+) pattern. This chance is increased with your Tears stat.

If the player has Mom's Eye and The Inner Eye the cross shot is always fired.

If the player shoots a charged Chocolate Milk shot, all of the cross pattern shots will be charged.

Bug: Sometimes it may appear before unlocking it.

Unlocked by defeating all of the Depths bosses.

Lokii Horns Isaac

Isaac gains small horns.


Lord Of The Pit


The player can fly over all obstacles, including damage floors, spikes, rocks, and pits. (Same effect as Transcendence, but with different visual effects).

A useful technique when you have acquired Lord of the Pit is to hover over a pit and shoot at walking enemies like Globins and Gapers. These enemies cannot get to you as long as you are above the pit.

Can be found in the Devil Room and after fighting The Fallen.

Trivia: There is an error in the spelling for the effect. It is quoted as "Deamon Wings". (This is a spelling error, but also might be an attempt at the old English spelling of the word, which is "daemon".)

File:Lord Of The Pit Isaac.jpg

Grants the player demon wings and turns the player's entire body black.


Luck Foot


All pills picked up will have positive effects (same effect as the PhD but without pill identification). Increases the chance of getting items from piles of poo and fires. Increases the chance of winning the Skull Challenge in the Arcade room from 33% to 50%. Increases the chances of getting items from gold chests.

As of WOTL version 1.48, it reduces the chance of getting random fortunes from the Fortune Telling Machine, and increases the chance of getting rewards from it.

Cain starts the game with this item.

Found in the Item Room, the Boss Room and Devil Room.

Unlocked by collecting 55 pennies in one playthrough.

File:Lucky Foot Isaac.jpg

Creates a gold anklet on Isaac's left foot.




Increases available heart containers by 1.

Found in Boss Rooms, and can be obtained from Beggars.

No visual effect. (A,4,3)

A Lump Of Coal


Increases damage based on how far tears have traveled (tear size increases as it gets further away).

If the Lump of Coal is "rerolled" with the D6, it may be replaced by other Devil Room items. In this case, the item will not cost any hearts.

Found after fighting Krampus.

File:Isaac Lump of Coal.png

Coal dust on forehead. Tears are stained black.


Magic Mushroom

File:Magic mushroom.png

Fully heals the player, increases all their stats by 1 (including available heart containers) and increases tear size.

Will give ??? a Soul Heart instead of healing.

A reference to Super Mario Bros.

File:Magic Mush Isaac.jpg

Player becomes visually larger.




Attracts coins, bombs, hearts and keys towards the player from a set distance (about 7-8 spaces). Objects can cross pits, spikes, and rocks. Will not draw in hearts if HP is full.

Note: It will also attract troll bombs towards the player.

Magneto will only attract eternal hearts when health is not full (Like red hearts).

File:Magneto Isaac.jpg

Isaac has a magnet on his head.


The Mark

File:The mark.png

Increases Damage by 2 and adds one soul heart.

Will kill you if you have 2 or less hearts when you make the devil deal despite giving you one soul heart.

Available by defeating The Fallen or traded in a Devil Room.

File:The Mark Isaac.jpg

Isaac sports three 6's in a circular pattern.


Max's Head


Increases damage by 1, increases the size of tears and causes tears to inflict more knockback on enemies.

Note: Even though it only appears to increase damage by 1, a single tear will kill attack flies, and kill Pooters and Horfs in two hits.

File:Max's Head Isaac.jpg

Isaac's eyes grow bigger and more shiny.



Mini Mushroom


Increases speed and range by 1.
Shrinks Isaac's hitbox, making dodges easier.

File:Mini Mush Isaac.jpg

The player's size decreases.

Movie strip


Mom's Contacts


Gives the player a petrifying shot that will randomly freeze enemies solid for 2.5 seconds and turns tears bright red.

If the body of a Mr. Maw enemy is frozen when the head launched, the head will detach but then reattaches when the body is unfrozen.

Note: The freezing effect will not work on Mom, but it will work on It Lives and invulnerable enemies (Statues in The Depths, Knights attacked from the front, etc).

Unlocked by collecting Mom's Eye and any other Mom's item on the same run.

File:Mom's Contacts Isaac.jpg

Isaac gains a red eye.


Mom's Eye

File:Moms Eyes.png

Increases Tears stat and gives the player an eye on the back of his head, allowing you to shoot in both directions at the same time.

The shots from the back fire at random, so having a faster firing rate means a more common multi-shot.

Fires normal tears, even when used in combination with items like Technology.

Mom&#039;s Eye

Isaac gets another eye on the back of his head.


Mom's Heels


Increases Range by 2.

This is mainly a Boss Room item. It can rarely be found in other places.

File:Mom's heels.jpg

Isaac wears mom's shoes.


Mom's Knife

File:Moms Knife.png

Once collected, Isaac no longer shoots tears, he shoots the knife from his mouth boomerang style. The range of throw increases by charging the shot. It can also be shot diagonally by using two arrow keys. Mom's Knife passes through enemies on its arc.

Can also be used as a melee weapon, in which case it does high damage and possibly instantly kills any enemies that its edge touches.

It is possible through the use of two or more range down pills to make it impossible to throw the knife, effectively resulting in a forced melee mode.

The knife is tied to your base damage and shot effects (e.g. spider bite or chocolate milk).

Finding Dr Fetus after Mom's Knife will replace the knife with the Dr. Fetus effect.

Finding Epic Fetus after Mom's Knife will give you the knife's effect for the current room, and when you leave the room you get the Epic Fetus effect.

When you combind Mom's Knife and Technology 2 you will have the beam and the knife, but the knife is the only one with damage source.

Having collected the Common Cold covers the blade in poison, to the point where it drips to the ground. Turns the blade gold or yellow when Number One is collected. Also turns the blade ghostly grey when the Small Rock is collected. If you pick up the Ouija Board your blade will become transparent.

When using My Little Unicorn (or the Chariot card) the Knife does not disappear, allowing you to stab, throw the knife, and charge around at the same time.

Good interaction with Wiggle Worm, if thrown correctly it hits multiple times before returning, causing enough damage to kill Mom in 3 hits.

When the Candle is used with a Wiggle Worm Knife, the Knife stalls in the air when thrown or used when walking.

Collecting the Spoon Bender item will add a slight homing effect to Mom's Knife. The path of the knife will shift slightly towards an enemy and shift back on return.

if the player has choclate milk, the knife will become extremly powerful and will kill most bosses with one hit (even mom, It Lives/moms heart and satan)

Unlocked by beating Sheol with Isaac.

File:Mom's Knife Isaac.jpg

Isaac wields mom's knife and wears her dress.


Mom's Lipstick


Increases Range by 1.

This is mainly a Boss Room item. It can rarely be found in other places.

File:Mom's Lipstick.jpg

Isaac wears mom's lipstick sloppily.


Mom's Underwear


Increases Range by 1.

Found in the Boss Room or rarely in the Item Room.

File:Mom's Undies.jpg

Isaac wears Mom's panties.


Money = Power


Increases damage based on the number of coins the player has at the moment. (10 coins = 1 extra damage).

Found in the Item Room or Devil Room.

Unlocked by completing the game 8 times.

File:Money Equals Power Isaac.jpg

Isaac gets pimpin' glasses.


Mr. Mega


Gives the player 5 bombs, and makes all dropped bombs large bombs (the same sized bomb dropped when Mr. Boom is used). Increases the damage of bomb, noticeable in boss fight.

Note: If the player has the Dr Fetus powerup (converting your shots to bombs) then it also applies to those bombs.

Bug: When combined with the Bucket of Lard powerup, causes a flicker effect on the character (due to overlapping textures).

Unlocked by using a lot of bombs.

Found in the Item Room, and shops

File:Mr Mega Isaac.jpg

Gives the player a helmet/facial expression similar to Wrath, who in turn is a reference to Bomberman.

Movie strip


My Reflection


Gives the player's tears a boomerang effect and range is set to default range.

Note: Any additional range adds to the distance of the boomerang effect. However it ultimately limits your prime range to medium. Flinging the shots by firing while walking forward drastically improves the maximum distance they will travel with this upgrade. The shots are actually drawn to your current location, meaning that you can 'pull' them in a direction by walking that way. This also means that if they go through you, they will turn around and start heading back again, etc until they reach their maximum range or hit something.

Bad in conjunction with Ipecac.

Works well in conjunction with Ouija Board, Cupid's Arrow, The Inner Eye, Lump of Coal, and/or Spoon Bender.

File:My Reflection.jpg

Isaac gains a Sailor Moon type symbol on his forehead.



Number One


Sets the player's tears to their maximum rate of fire and minimum range.

Combining Number One with Technology causes the fire rate to increase significantly and turns the beam yellow.

Bug: Collecting The Mark (and maybe other tear-changing items) before collecting Number One increases your rate of fire to max, but doesn't decrease your range.

File:Number one!.jpg

Isaac stops crying and smiles while yellow colored projectiles (urine) come from his lower body rather than his face.


Movie strip


Odd Mushroom (Thin)


Increases speed by 1, increases Tears to maximum (Rate of fire) while reducing projectile damage by 1.

Found in the Item Room and Shops.

File:Odd mush thin.jpg

Makes player's head smaller.


Odd Mushroom (Large)


Increases damage by 1, and increases maximum hearts by 1 while reducing speed.

Found in the Item Room and Shops.

File:Odd Mush Flat Isaac.jpg

Makes player's head bigger.


Ouija Board

File:Ouija Board.png

Allows the player's shots to go through rocks or obstacles, but unlike other piercing upgrades will not pierce enemies and will not damage Knights from the front.

Shots will be stopped by stone-turret-heads, but they will be moved by the shot.

Tears go through fire, poop, TNT barrels and extinguish/destroy/detonate them at a slower rate than usual (unless combined with Technology, in which case they're all destroyed instantly). Familiars' shots are not affected by some of these changes. For instance, Brother Bobby's tears will still put out fires. Also works with Dr Fetus upgrade.

Available in the Devil Room, Item Room or from Beggars.

File:Ouija Isaac.jpg

Makes Isaac's head look undead or soulless.



The Pact


Increases Damage by 1 and rate of fire by 2. The player also gains 2 soul hearts.

If you have Transcendence when you pick up The Pact, you will have a body again, but with demon wings like the Lord of the Pit item grants.

Available by defeating 'The Fallen' or traded in a Devil Room.

File:The Pact Isaac.jpg

Turns the player's body black, gives him small horns, and makes him seem more aggressive.


The Parasite


Makes the player's tears split in two when they hit something. Sets firing rate to 1. Stains tears brown-orange.

Note: tears only split when they stop. That means with piercing upgrades (i.e. Cupid's Arrow/Brimstone) they won't split on enemies.

Unlocked by collecting two "dead things" (Bob's Rotten Head, Guppy, Max's Head, Tammy's Head) in a single playthrough.

Does NOT split bombs when used in conjunction with Dr. Fetus. It only changes the color of the bomb to orange and the explosion turns orange as well.

File:Parasite isaac.jpg

A creature appears on Isaac's head that looks like the Parasite from the Flash-Game "The Visitor" by Zeebarf.





Increases Damage by 2. Increases chance for a Devil Room to appear.

Unlocked by completing The Womb with Cain.

Familiar: Follows the player. (A,4,10)

Isaac begins to cry much harder.


Sister Maggy


Follows the player around shooting blood tears.

More powerful than Brother Bobby. (Blood tears deal more damage than normal tears.)

Sister maggy

Familiar: Follows the player.




All the various fly type enemies no longer harm you, shoot, or split.

Note: Boom Flies will still be harmful, but their speed is reduced. Suckers will also still fire their shots when they die. An attack fly that has newly spawned will still need to 'convert' into a simple black fly, and touching it will damage you.

Final reward for Shell game in Arcade.

Unlocked by completing the Caves.

File:Spelunker Isaac.jpg

Isaac wears a miner's helmet.


Spider's Bite

File:Spiders Bite.png

Gives the player's shots a chance of slowing enemies for 2.5 seconds. The projectiles from a slowed enemy are also slowed but retain their air time, effectively reducing their range. Turns tears white.

Note: This will work against statues in The Depths and against Knights from the front.

This item will only appear in a Secret Room.

If used with Brimstone the laser will slow enemies.

Unlocked by completing the Basement .

File:Spider bite.jpg

Trivia: A cameo from another of Edmund's game, Time Fcuk.

Dropped by Steven. Can also be found rarely in golden chests (even before unlocking him as a boss).

File:Steven Isaac.jpg

Isaac gains a little tumor buddy.


Super Bandage


Increases HP by 1 and gives 2 soul hearts.

Trivia: This is a reference to "Bandage Girl" from Super Meat Boy, another game Edmund McMillen worked on.

Rarely found in Boss Rooms.

Also makes a unique sound on pickup.

Unlocked by getting a level 4 meatboy AND beating 4 horsemen in boss rooms in one playthrough.

File:Super bandage.jpg

Isaac gets things like a bandage and a flower. Resembling Bandage Girl.




Gives the player a laser shot with unlimited range. Shots pierce enemies but not rocks, fire, or poop. Shots can't be angled, and will not provide knockback. Shots come from Isaac's left eye only (so if you aim up, they are to the left, down they are to the right, left they are below your aim, and right they are above it).

If you have Technology and Dr Fetus at the same time, you will fire both a bomb and laser simultaneously.

Shots can still be charged with Chocolate Milk, which makes them stronger and visually wider.

Brimstone has priority over Technology. If you already have Brimstone, picking Technology will have no effect. If Brimstone is taken after Technology, it will override it.

If A Lump of Coal is picked up after technology, damage is increased. (Maxed?)

Creates a wobbly beam when used in tandem with the Wiggle Worm. This increases the beam's width slightly.

When combined with Ouija Board or Spirit of the Night, the beam becomes transculent and passes through objects.

When combined with Polyphemus or Mutant Spider, it creates a large laser that does Maximum damage, but can only be fired periodically (about 1.5 seconds in between shots).


Isaac gets a cyborg eye.





Removes the player's body, allowing flight over obstacles, spikes and pits.

If you have an upgrade which makes your player's body look demonic (like The Pact or The Nail), Transcendence will give you black demon wings instead of simply removing the character's body. This happens regardless of whether the demonic item is acquired before or after Transcendence.

This item appears only in Secret Rooms.

Unlocked by completing the game twice.

File:Transcendance Isaac.jpg

Isaac becomes a floating head.


Treasure Map


Reveals all rooms for every floor, including the Secret Room. However, it does not reveal icons.

If you only have The Compass and see a mini-boss icon, you are sure to meet Greed there if you collect the map and it shows the secret room at this point.

Common in Shops and occasionally found in Challenge Rooms. Often given by Beggars.

No visual effect. (A,1,7)

The Virus

File:The Virus.png

Gives the player the ability to deal damage to, and poison, enemies they touch for 2.5 seconds. The player will still take damage from touching enemies, but remember that not every enemy can hurt you by touch!

Small black flies (not the flashing ones) can be killed by running into them without taking damage.

This item is sometimes dropped by Lust, or found in the Challenge Room.

File:The Virus.jpg

Isaac becomes diseased.


The Wafer


Reduces all damage received by half, rounding up to the nearest half-heart. This includes the damage received from using a Blood Donation Machine in The Womb.

Unlocked by completing the game 7 times.

File:The Wafer Isaac.jpg

Isaac starts glowing around his head.


Whore of Babylon


If you have half a heart, a message reading "What a horrible night to have a curse..." appears on the screen and the player becomes the Whore of Babylon. This increases their damage by 3 and speed by 2 and they will stay in that form until leaving a room with more than half a heart.

Note: If ??? picks this up, he permanently gains its effects upon leaving the room for the remainder of the game.

Bug: Avoid buying it while having plenty of soul hearts and only one red as it will leave you with no hearts at all and you'll die on first hit.

*Note that Edmund McMillen (the creator) has said that Whore of Babylon and similar items are damage multipliers.

Source: Video

Trivia: The pop-up message when activated is a reference to the NES game "Castlevania 2: Simon's Quest" when nightfall comes.

Eve starts the game with this item.

Found in the Devil Room, Item Room or after defeating The Fallen. Might appear in the shop for 2 hearts or 15 coins as well.

When activated while the player has Fate, the Holy Grail, or the Bible activated, the wings turn black.

File:Whore of Babylon Isaac.jpg

Isaac becomes a spawn of Satan.


Wiggle Worm


Gives the player waving shots and increases attack speed by 1; these do not angle with movement.

Note: Good interaction with Mom's Knife; if thrown correctly it hits multiple times before returning.

Good interaction with Technology, as it will cause the beam to snake, increasing its area of effect. Does not synergise with Technology 2's beam but does with normal tears.

May increase homing effect for homing tears.

Found in the Shop or Item Room.

File:Wiggle Worm.jpg

Isaac's eyes shrink and become jittery.

X-Ray Vision


Reveals and opens Secret room entrances.

Trivia: The effect is described as "I've Seen Everything," a reference to Patrick Stewart's appearance on British sitcom "Extras" alongside Ricky Gervais.

Note: This can create exits from the Secret Room that are normally not possible, such as exiting into a Boss Room.

This item can be exploited to indefinitely recharge items with the Battery by entering and leaving a room with enemies without clearing it as needed.

File:X-Ray Specs Isaac.jpg

Isaac wears X-Ray glasses.


Wrath of the Lamb Collectible Items

The following collectible items can only be acquired in the Wrath of the Lamb DLC.

Name and Icon Effect Info Collection Grid (Pg,X,-Y)

3 Dollar Bill


Effect given changes every room. It can give you the effect of: Mom's Contacts, My Reflection, Number One, Ouija Board, Spoon Bender, The Inner Eye, Tough Love and Magneto (via bug).

Since it can grant the Magneto effect, it can be used to aquire items (bombs, keys etc.) you otherwise couldn't, by repeatedly leaving and re-entering a room.

Also a very bad synergy caused by My Reflection effect from 3 Dollar Bill with IPECAC. It causes IPECAC shots to follow the player until they hit an obstacle or wall.

The name most likely comes from the slang "Queer as a 3 dollar bill".


Isaac appears to be happy. Stars appear around his eyes when he fires tears.



File:Wotl abel.png

The Ankh triggers before 1up.

New. With the Dead Cat item, if you die as ??? you will respawn as your previous character with 1 Heart Container.

Note: The Ankh effect will occur before the effect of the Dead Cat, so you will first respawn as ??? before using up any of the 9 lives obtained via the Dead Cat.

Trinkets were a new addition with the Wrath of the Lamb DLC.

The current Trinket is shown in the top left corner of the screen, under the map (opposite to the current Collectible Item in the top right corner).

Name & Image Effect Info
???'s Soul

Gives you a Familiar that looks like Brother Bobby and floats slowly around the room on a pattern similar to The Peeper, shooting long-range spectral homing tears that have high Shot Speed.

If you have other familiars, they will follow ???'s Soul instead of Isaac. This does not include Orbitals, Blue Flies, or stage 3/4 Meat Boy and the body created by The Pinking Shears.

This item is meant to be unlocked by completing The Chest with ???. However, due to a bug it is instead unlocked by completing The Chest with Eve.

Ace Of Spades
Increases the chance of Tarot Cards or Suit Cards dropping after clearing a room, and the chance of finding Cards when opening a Chest.

Chance of finding a Card when clearing a room is increased by 10%.

Chance of finding a Card when opening a Chest is increased by 66%.

Bloody Penny
Gives a 50% chance to drop a Half Heart when money is collected.

Unlocked by completing Cathedral with Samson.

Hearts dropped through the use of this trinket will always be Half Hearts, and are not affected by items such as Mitre or being spawned in special rooms such as Cathedral Super Secret Rooms.

Effective trinket for Blood Donation Machine use, as the money dropped by the machine will often create a Half Heart, effectively making that use "free". This is even more pronounced with the IV Bag, since it is possible to create as many as four coin drops per Half Heart spent via the item.

Burnt Penny
Gives a 50% chance to drop a bomb when money is collected.

Unlocked by completing the Large Marge challenge.

Bombs dropped through the use of this trinket will always be single Bomb pickups.

Cain's Eye
When starting a floor, 25% chance to get the The Compass effect for the duration of a floor. Unlocked by completing The Chest with Cain.
Decreases Tears Delay by 2. The effective fire rate increase varies depending on Isaac's current Tears stat. The higher the Tears stat, the higher the percentage increase in fire rate from Cancer. See the Tears section on the stats page for detailed calculation.
Child's Heart
Increases the chance of a Heart dropping after clearing a room, and the chance of finding a Heart when opening a Chest.

Chance of finding a Heart when clearing a room is increased by 10%.

Chance of finding a Heart when opening a Chest is increased by 66%.

Hearts dropped due to this trinket are treated as normal heart drops: they have a small chance to appear as Soul Hearts or Eternal Hearts. Items such as Mitre or Mom's Pearl will affect this chance.

Counterfeit Penny
Gives a 50% chance of increasing the value of every coin pickup by one. Can only be found in Golden Poop. Unlocked by completing the Isaac Was Good Today challenge
Cursed Skull

If Isaac has less than one full Red Heart after taking damage, he will be immediately teleported to the last cleared room he was in.

The Cursed Skull only counts Red Hearts, and does not count Soul Hearts or Eternal Hearts. Even if the triggering damage is absorbed by a Soul Heart or Eternal Heart, Isaac will still be teleported if he has half a Red Heart or less.

Due to the above, ??? will be teleported any time he takes damage while holding this trinket, as will any character who has reduced their heart count to zero via other means.

Synergies: + Scapular = Partial immortality, a 1 heart hit could still kill you. + Scapular + Wafer = Complete immortality.

Curved Horn

Increases Effective Damage by 2.

Unlocked by completing The Cathedral with Judas

Rather than increasing the Damage stat, the Curved Horn increases the Effective Damage of Isaac's tears. Because the Damage stat increases Effective Damage by smaller and smaller amounts with each increase, this makes the trinket considerably more valuable at higher levels of the Damage stat. See Damage on the stats pages for a detailed calculation.

Eve's Bird Foot

5% chance to spawn a Dead Bird familiar for the current room each time an enemy dies.

This item is meant to be unlocked by completing The Chest with Eve. However, due to a bug it is instead unlocked by completing The Chest with ???.

The Left Hand

Replaces all normal chests with Red Chests. Gold chests are affected as well.

Unlocked by defeating Ultra Pride.
Liberty Cap
25% chance of giving Isaac a random passive effect from Mushrooms as well as its corresponding visual effect upon entering a room.

Bug v1.48: Can also randomly add The Compass effect.

Possible mushrooms: Mini Mushroom, Odd Mushroom (Large), Odd Mushroom (Thin).

When playing as ???, this Trinket will generate a spirit heart when you gain the health up effect from Odd Mushroom (large). This spirit heart does not disappear when you exit the room. This effect only applies once per playthrough.

Lucky Toe

Increases the chance to get a drop after clearing a room. Although the Luck stat also influences this, it does not actually increase the Luck stat.

The increase in drop chance is applied before the effect of Guppy's Tail.

Unlocked by Completing the 7 Years Bad Luck challenge.

Increases the chance of a generic drop from clearing a room by roughly 10%, the same amount increased by the Lucky Foot item. If Isaac's Luck stat is not negative, this raises the chance of an item dropping from 86.6% to 96.3%.

If Isaac also has the Lucky Foot and his Luck stat is not negative, the chance for a drop is only increased by 2% instead. This raises the chance of an item dropping to 98.3%.

If Isaac has a negative Luck stat and the Lucky Toe with or without the Lucky Foot, there is a 100% chance that an item will drop after clearing a room.

Maggy's Faith
Gives an eternal heart at the start of every floor. Unlocked by completing The Chest with Magdalene.
Match Stick
Increases the chance of Bombs dropping after clearing a room, and the chance of finding Bombs when opening a Chest.

Chance of finding a Bomb when clearing a room is increased by 10%

Bombs dropped due to this trinket are treated as normal Bomb drops, and can appear as single pickups, double pickups, or even Troll Bombs.

A Missing Page

5% chance to induce The Necronomicon's effect upon taking damage.

Mom's Pearl

Grants a secondary 10% chance of any non-specific Heart drop turning into a Soul Heart.

The secondary chance triggers whenever a non-specific Heart drops which does not become an Eternal Heart or Soul Heart. It is applied after Eve's secondary 6.25% chance, but before Mitre's secondary 50% chance.

By itself, Mom's Pearl raises the chance of a non-specific Heart dropping as a Soul Heart from 9.8% to 18.62%. Combined with Eve's bonus, the chance becomes 23.58%. Combined with Mitre, the chance is 58.31%. Combined with both Mitre and Eve's bonus for the highest possible bonus, the chance is raised to 60.79%.

Pinky Eye
10% chance to fire a poison tear. There's a possibility to fire poisonous bombs with Dr. Fetus.
The Polaroid

If Isaac survives damage with less than one red heart, he will receive a shield similar to the Book Of Shadows for 5 seconds. This effect ignores other heart types and thus always works for ???.

Holding The Polaroid while opening the big chest at the end of the Cathedral will allow you to continue to The Chest.

Unlocked by completing Cathedral six times. You may use the same characters for all six completions.

In 1.4 through 1.48 it is always dropped by Mom upon completion of The Depths 2.

Push Pin
10% chance to fire a spectral and piercing tear.
Red Patch
20% chance to increase damage upon taking hit, as if Razor Blade was used. Isaac loses his skin for the duration of the room. If Isaac has flight, loses body as well (visual effect similar to Transcendence).
Rusted Key

Improves the chance of Keys and Golden Chests dropping after clearing a room, and chance of finding a Key when opening a Chest.(see info)

This item has no effect from v1.48 to v1.666. (Source - Reddit)

Chance of finding a Key or a Golden Chest when clearing a room is increased by 5% for each.

Chance of finding a Key when opening a Chest is increased by 66%.

Safety Cap

Improves the chance of Pills dropping after clearing a room, and chance of finding a Pill when opening a Chest.

Chance of finding a Pill when clearing a room is increased by 10%.

Chance of finding a Pill when opening a Chest is increased by 66%.

Samson's Lock

1/15 chance to increase damage by 0.5 for the current room each time an enemy dies.

Unlocked by completing The Chest with Samson.

Stacks with Bloody Lust, but chance to trigger is too low to be worthwhile.

The Tick

Drain 15% health of each enemy with more than
60 HP (ie. most bosses).

Also restores one red heart of Isaac whenever he enters an uncleared boss room.

The Tick is stuck into Isaac's head and cannot be swapped out for another trinket.

Bosses like Larry Jr. / Fistula are made up of entities with less than 60 HP, so their HP are not leeched.

Might be disadvantageous when playing with Eve, as Whore of Babylon will deactivate when entering boss room due to restored health.

The player will be unable to access The Chest without the use of Mom's Purse, as the nature of this trinket makes it impossible to pick up The Polaroid.

Umbilical Cord
When Isaac's health is brought to half a red heart, a Little Steve familiar spawns. Applies only to the room in which Isaac took damage. If Isaac moves to another room without regaining more than a half heart of health, the spawned familiar will still disappear.

If you already have a Little Steve, Brother Bobby will spawn instead.

Bug: The left hand drops from Super Pride even when it has already been obtained.

Tarot Cards

Tarot Cards Icon
Suit card

Card is a moderately common type of Pick Up which provides a special effect upon activation. Cards come with various properties:

  • They are stored in the upper right item slot, used by pressing "Q" and are one-time-use only.
  • Isaac may only carry one card or pill at a time. Attempting to pick up a second card or pill will cause him to drop the one he has been previously holding.
  • There are two types of cards in The Binding of Isaac: "Tarot Cards" and "Suit Cards".1
  • "Suit Cards" are only found in Wrath of The Lamb. They act like a special replacement for Tarot Cards, and have a 20% chance of replacing them.
  • Unlike Pills, a particular type of card will always have the same effect. However, all tarot cards share the same icon, and therefore cannot be identified until picked up.



Major Arcana

Item Icon Item Name Effect
0 The Fool


The Fool

Teleports the player to the starting room of the current level, even if you use the card in the starting room.

TIP: This card has little use, but it can teleport you out of inescapable rooms like the Challenge Room and the Mom boss fight, and the damage-upon-entry Curse Room. It can also teleport you out of problematic rooms in a pinch.

I The Magician


The Magician

Player's shots curve towards enemies and may turn purple until you leave the current room.

TIP: This effect is the same as Spoon Bender and Telepathy For Dummies; this card is useless in the case of the former and best used when the latter lacks charge.

II The High Priestess


The High Priestess

Summons Mom's foot stomp on a random enemy (targets the player if fighting Mom or if there are no enemies present), dealing massive damage — enough to kill most bosses and wiping half of Mom's own health if used on her. Acts as an explosion — will destroy rocks and can open secret rooms.
TIP: As mentioned, this card will target Isaac if no enemies are present in the current room; make sure that's something you want to do before you use this.

III The Empress


The Empress

Turns the player into a demon, increasing damage by 2 and speed by 1 until you leave the current room.
TIP: This effect is the same as Whore Of Babylon; as such, this card is useless if you already have this item and it is active.This card is best saved for a room you're going to stay in for awhile, such as a Challenge Room or the Boss Room.

IV The Emperor


The Emperor

Teleports the player to the Boss Room. If used while fighting the boss, the fight will restart and the boss will be back at full health. (Will be the same boss, but could possibly change to a different colored version)

TIP: Always try to save this card for the final floor of your run; also keep in mind that you can use the inertia from running to take another card or pill into the boss room with you, if you're fast enough.

V The Hierophant


The Hierophant

Spawns 2 soul hearts.

TIP: It spawns these rather than adding them to your life, as Balls of Steel does; use this to your advantage, if you can.

VI The Lovers


The Lovers

Spawns 2 full hearts.

TIP: It spawns these rather than adding them to your life; use this to your advantage, if you can.

VII The Chariot (flipped)


The Chariot

Grants you temporary invincibility, and causes you to damage enemies with touch. However, you cannot attack unless you're holding Mom's Knife.
TIP: This is the same effect as My Little Unicorn, so this is best used when said item lacks charge.

VIII Justice



Spawns 1 random type of Bomb drop, Key drop, Coin drop, and Heart drop.

TIP: This can spawn anything dropped by clearing a room, like Troll Bombs, 1+1 Free, Soul Hearts, and nickels; with Wrath of the Lamb, you can also get Super Troll Bombs, Eternal Hearts, Golden Keys and dimes from using this card. Also, as with The Lovers and The Hierophant, it spawns these rather than adding them to your life and inventory; use this to your advantage, if you can. This card will spawn a specific kind of heart if a room forces it (full red heart in the womb-themed top secret room, eternal heart in the cathedral-themed top secret room).

IX The Hermit


The Hermit

Teleports the player to the Shop. If there is no Shop (or you are already in one), this will act as a random teleport.

TIP: This card can teleport you into a locked Shop, and you will open it without consuming a key if it does.

X Wheel of Fortune


Wheel of Fortune

Spawns a Slot Machine. In Wrath of the Lamb, this may also spawn a Fortune Telling Machine.

TIP: If you can, find a room with another Slot Machine, Fortune Telling Machine, or Blood Donation Machine to maximize gambling efficiency.

XI Strength

XI Strength

Makes the player bigger, increasing maximum health and damage until the player leaves the current room (same effect as Odd Mushroom (Large)). ??? receives a permanent spirit heart rather than a temporary maximum health increase, however this may be a bug.

TIP: This card is best saved for a room you're going to stay in for awhile, such as a challenge room or the boss room; it can also be used as a last-ditch healing effort.

XII The Hanged Man


The Hanged Man

Removes the player's body allowing flight over obstacles, spikes and pits until you leave the current room. If you have Brimstone, instead of removing the players body it will give them wings (All the same as single-use Transcendence).

TIP: This card is useless if you have any item that already allows flight, such as Transcendence (as Item), Lord Of The Pit, Fate, or the Holy Grail.

XIII Death



Damages all enemies in the room significantly.

TIP: This does the same thing as the The Necronomicon, and they can be devastating to enemies in the room if you use them in quick succession. This technique is best saved for Bosses, though; especially those that like to spawn lesser enemies.

XVI Temperance

XVI Temperance

Spawns a Blood Donation Machine.
TIP: If you can, find a room with another Slot Machine, Fortune Telling Machine, or Blood Donation Machine to maximize gambling efficiency.

XV The Devil


The Devil

Increases your damage by 2 until you leave the room.

TIP: This has the exact same effect as The Book Of Belial bar the guaranteed devil with the devil chance on boss rooms. Using both in the same room will not cause the damage to stack.

XIV The Tower


The Tower

Spawns six troll bombs around the room.

TIP: This does the same thing as the Anarchist Cookbook, and they can be devastating to both yourself and enemies in the room if you use them in quick succession.

The Stars


The Stars

Teleports the player to the Treasure Room. If there is no Treasure Room, this will act as a random teleport. Randomly chooses a Treasure Room in XL floors.

TIP: This card can teleport you into a locked Treasure Room, and you will open it without consuming a key if it does.

XVIII The Moon


The Moon

Teleports the player to the Secret Room. This card will open one random wall once inside the Secret Room, so you can leave even if you don't have any bombs available.

TIP: This card can teleport you out of inescapable rooms like the Challenge Room and Mom's room. It can also get you out of problematic rooms in a pinch.

XIX The Sun


The Sun

Completely heals player, damages all enemies, and reveals the entire map and location of special rooms for the current level. (Same effect as XXI The World and a Full Health pill combined, though unlike a Full Health Pill, it will not heal ???.)

TIP: Try to use this card in an uncleared room or on the Boss, if you need to use it at all.

XX Judgement

XX Judgement

Spawns a beggar. In Wrath of the Lamb, this may also spawn a Devil Beggar.

TIP: Try to wait until you get into a Devil Room or an Angel Room to use this card; if you do and give the Beggar enough money, he will leave behind an item specific to that room instead of a more random item. If you cannot get either before leaving this card behind, use it in the Curse Room or the Secret Room.

The World-flipped


The World

Reveals the entire map and location of all special rooms for the current level.
TIP: This is less useful if you have either Treasure Map or The Compass, and completely useless if you have both, or you've revealed the map via things like the Crystal Ball, a Sun card or another World card.

Minor Arcana

Item Icon Item Name Effect
Shape670 The Joker

Transports you to the Devil Room. Exiting places you in the starting room of the floor.

The Devil Room acts as usual: it may randomly contain Krampus, get replaced by an Angel Room and will contain a trapdoor to Sheol in Level 2 of Chapter 4.

Therefore if you access it on a floor before fighting the boss, take the items inside and get regular access to it later in the boss room, the Devil Room won't contain new items.

Also allows getting to the Devil Room in situations in which it would be otherwise inaccessable.

Shape668 2 of Hearts

Doubles your Hearts (up to full health). If you have half a heart left, recovers your first two Heart Containers. (Spirit Hearts are unaffected.)

Example: Given you have 7 Heart Containers, 2 Spirit Hearts and 2.5 Hearts left. Using the card will heal you for 2.5 hearts, so you will have 5 of 7 heart containers filled, and 2 Spirit Hearts.

Useless for ???.

Shape666 2 of Spades

Doubles the number of Keys you currently have. If you don't have any Keys, provides you with two.

Shape667 2 of Clubs Doubles the number of Bombs you currently have. If you don't have any Bombs, provides you with two.
Shape669 2 of Diamonds Doubles the number of Coins you currently have. If you don't have any Pennies, provides you with two.


  • A Tarot Deck is a traditional deck of playing cards with 78 cards from the mid-15th century. Unlike a standard 52-card deck, the Aces are usually replaced by pip cards with the number 1. In addition, it also contains four suit cards with a Knight that ranks between the Jack and the Queen, as well as 21 trump cards with numerals from 1 to 21, as well as the Fool, which is unnumbered.
    • Divinatory tarot originates from this. Here the 21 trump cards and The Fool are called the Major Arcana, while the remaining cards with the regular suits are called Minor Arcana. Cards from the Major Arcana are the most significant cards for divination.
      • The "Tarot" cards in The Binding of Isaac are all of the Major Arcana cards from Divinatory tarot.
  • The tarot cards featured in The Binding of Isaac are likely based on the Tarot of Marseille and the Rider-Waite tarot, two of the most well-known divinatory tarot decks: The drawings on the tarot cards in The Binding of Isaac seem to be based on the art from Tarot de Marseille. However, this deck does not give a numeral to The Fool, and traditionally uses different names for some cards, also omitting for the thirteenth card entirely (XIII Death in-game). Tarot card names in the game are identical to the Rider tarot, and in this deck, The Fool is indexed with a Latin 0.
    • The card The Star is called "XVII The Stars" in-game.
    • Like most traditional or divinatory decks, these tarot decks do not use the more well-known modern French suits (Spades, Hearts, Diamonds, and Clubs) in the Minor Arcana. Instead, it uses Italian tarot suits: Swords, Cups, Pentacles, and Wands.
      • Therefore, the cards added in Wrath of the Lamb (the four pip cards with the number 2 and the joker) are not part of the Rider-Waite deck. Instead, they seem to be part of a standard-52 card deck ("French Deck") with Jokers, used for playing games like Canasta, Rummy, or Poker. The same goes for the trinket Ace of Spades (the Ace of Spades is one of the highest-ranking cards in many games that use the French Deck).
  • Getting killed by The High Priestess card via Mom's leg will show a Bomb as the cause of death on Isaac's Last Will.
  • If you lose all heart containers and you have no spirit hearts (by deal with Satan), Strength won't give you a temporary heart container and you will still be killed after any damage.
  • Edmund has stated that The Moon is his favorite Tarot Card.[1]
  • On June 26, 2013, nine Steam Trading Cards were added for The Binding of Isaac, with each card carrying the appearance of a tarot card; the cards range from 0 The Fool to VIII Justice. Each card features a character and/or item(s) from the game, and they're illustrated in a way that represents both the real tarot card it's based on, and what that specific card does in-game.
    • 0 The Fool Trading Card shows Isaac immediately after falling into The Basement, representing how the Fool card in-game brings you to the starting room of the current floor.
    • I The Magician Trading Card shows Judas reading the Telepathy For Dummies book with the third eye it provides when used. This represents how The Magician gives you homing tears for a single room when used in-game, which is the same effect that Telepathy For Dummies gives you. It also shows the Spoon Bender item, which also gives Isaac homing tears, and the Magic 8 Ball.
    • II The High Priestess Trading Card shows Isaac blood dripping on his forehead from Mom's Knife. This is representative of how II The High Priestess in-game summons Mom's Foot, which also has a chance of damaging Isaac if one isn't careful when using the card.
    • III The Empress Trading Card shows Eve on a simple throne holding her bird, with an apparition of herself in Demon form behind her. This is a representation of how The Empress card in-game gives you a single room Whore of Babylon effect; the same item Eve starts with.
    • IV The Emperor (Misspelled as "Emporer" during the initial release of the trading cards) Trading Card shows ??? on a golden throne with all the bosses you can find in The Basement before unlocking anything behind him, representing how the Emperor card sends you to the boss room of the current floor you're on in-game.
    • V The Hierophant Trading Card shows Isaac having The Mitre being placed on his head by The Angel Room's Angel / God with two soul hearts on either side of him. This represents how V The Hierophant spawns two soul hearts in game; The Mitre increases the chance of Soul Hearts spawning.
    • VI The Lovers Trading Card shows Maggy holding her Yum Heart with a ribbon around her and two hearts on either side of her, representing how VI The Lovers spawns two hearts as well. The Yum Heart also heals you for one heart, tieing in with the theme of health.
    • VII The Chariot Trading Card has Isaac using the My Little Unicorn item with a bright rainbow flashing behind him. representing how VII The Chariot makes you invincible for a single room; the same effect that My Little Unicorn gives you when used. He's also holding The Black Pony and The White Pony, which is in reference to the two horses on the Chariot tarot card.
    • VIII Justice Trading Card shows Isaac blindfolded with a rag similar to that of Conquest's, and he is holding a sword. There are also two balancing scales behind him, each holding, in clockwise order from top-right, a penny, a key, a bomb, and a heart, representing how the Justice card in-game spawns one of each pickup.


  • fegtance card will sometimes appear with the wrong Roman numeral, namely XVI (the number of The Tower). It still has the same graphic and name otherwise.
  • If a teleporting card is used while Isaac is exiting a room, the teleportation will not occur.
  • On rare occasions, the Secret Room may not spawn on a floor. In such cases, using XVIII The Moon will not teleport Isaac to the Super Secret Room, but to a random room on the floor.
  • Using the High Priestess card and then hitting 'pause' and waiting for about one second once the foot hits the ground will cause it to stomp again; this process can be repeated indefinitely.
  • The High Priestess is affected by bomb resistances. It will deal less damage depending on the specific case.

Pill Effects

For a complete list of pills and effects, see the above link

Pills are random items that are dropped by enemies, found in chests, or spawned in rooms, and are used by pressing 'Q'. They come in many colors and the effects change every time you play. If you use a pill and pick up a 2nd pill of identical colors, it will have the same effect as before and it's name will be shown, replacing "???".

Pill effects can vary from one-off effects to permanent changes. Both the PhD and Luck Foot items replace all negative pill effects with positive ones (except Explosive Diarrhea, Telepills, and Bad Gas). You may only have one card or pill at a time, and picking up another card or pill will cause you to drop the other one.

Notice that you will only encounter six of these pill effects in one playthrough, since there are no more than six different sprites of pills.

"Pills Here!" is item (8,5) on the collection list and is unlocked by finding any pill.

Pill Blue Blue Ground Pill Blue Blue Menu Pill White Blue Ground Pill White Blue Menu

Pick Ups

Pick Ups are random items that are dropped by enemies, spawned in rooms, given by beggars, won in slot machines/shell games and found in chests, fires, poop piles and blue rocks. They are consumed by walking over them. In the case of hearts, you will not pick up a heart or attract it with Magneto unless you are damaged.

Note : Only 12 hearts will be displayed at a time (regular and soul hearts). You can only have a maximum of 12 regular hearts. Soul hearts are not restricted in this way.

Item Icon

Wrath of the Lamb Pick-Ups

The following pick-ups can only be acquired in the Wrath of the Lamb DLC.

Item Names


Blue Fly

Blue fly

An attack fly which will circle the player and charge the closest target once within a certain range. It will most likely die in the process, unless enemy is very low on health or generaly weak. Surviving a Blue Fly will look for new target or continue to orbit Isaac. There is no known limit of Blue Flies in a single room, however a max of 5 orbiting flies will follow Isaac into the next room. Unlike the other orbital familiars (such as black/red attack flies and the Guardian Angel), the blue attack fly has some delay when the player is moving, causing it to slightly follow before falling back into orbit once the player stops moving.

Eternal Heart


Adds half of one white heart, lost before normal hearts, but after soul hearts. When using Blood Donation machine, the white heart is lost first. Changes to a full normal heart container after the floor is completed, or if a second eternal heart is acquired before completing the floor. May spawn instead of a regular heart. (Using the Forget Me Now will automatically complete an eternal heart as if you finished a floor.) Half an eternal heart will not sustain ???'s life, but he is able to gain a soul heart by completing the eternal heart. If buying a Devil Room item would use up all of your hearts except an eternal heart, Isaac will die, but there will be no death animation.



Worth 10 coins. May spawn instead of a regular coin, albeit even rarer than a Nickel. The Dime looks similar to the Nickel's pre-expansion appearance (as of Wrath of the Lamb, the Nickel now appears much darker).

Golden Key

File:Goldfen key.gif

Allows you to open any door or chest on the current floor without using up regular keys. Will also let you unlock doors without having any normal keys. Lost upon moving to the next level. Can be acquired by being a random pick up item.

Mega Troll Bomb

File:Huge troll bomb.png

Homes in on Isaac very quickly (similar to having Magneto). Has a greater damage radius (similar to Mr. Mega). Used by Super Wrath and Super Pride. Occasionally found in curse chests and has a rare chance spawn like regular Troll Bombs (from chests or after a room is cleared). Text "TROLOLOLOL" will show up in the bottom-right corner when touched (also applies to the regular Troll Bomb). Can also follow you over pits and through rocks. Can be fired when you hold Mr. Mega, Bobby Bomb, and Fetus in a Jar.
