The Candle
Wrath of the Lamb saw the addition of ten challenges. More details about each challenge and their unlockable items can be found on the challenges page.


35 achievements (orginally 24) were added with the Wrath of the Lamb DLC. What they are and their unlock requirements can be found on the Achievements page.


34 secrets were added with the Wrath of the Lamb DLC. What they are and their unlock requirements can be found on the Secrets page.


The Cellar

The Cellar is an alternative version of the Basement which can randomly replace one or both Basement levels in a playthrough. The enemies differ from those appearing in the Basement, featuring an increase in the number of spider-themed enemies, and areas of webbing appear in the terrain which slow Isaac's movement and the speed of tears that pass through. The Cellar's enemies/bosses are arguably harder than that of the Basement's, making it a challenge for newer players.

The Catacombs

The Catacombs is an alternative version of the Caves, and replaces the Caves levels in a similar fashion to how the Cellar can replace the Basement.


Necropolis is an alternative form of The Depths. It generally features harder versions of enemies from The Depths.


Identical in appearance to The Womb, Utero is identified by different enemies and boss types.


With Cathedral-styled walls, Cathedral is the polar opposite of Sheol and is the other option of floor to go after defeating It Lives. It features angel-based monsters (white bomb snakes, angel fetuses) and contains a new final boss. If the Forget Me Now is used in Cathedral, the player is spawned in Sheol (this is most likely a glitch).

The Chest

After you finish the Cathedral (beating Isaac with the Polariod) this new floor with starts out with four Golden Chests in the spawn room. Every room before the New Final Boss are rooms with two bosses (I.E. two Chubbs, two Peeps, two different Horsemen of the Apocalypse.) Beating this floor unlocks a new item and a Final Ending Cut Scene. (need to beat this floor with every single charater to unlock all the new items/achievements)


Angel Room

Angel Room
See Angel Room for more detail.

An alternative to the Devil Room. Item does not cost player hearts.

Curse Room

Costs 1 heart (Half a heart walking in, half a heart walking out) to enter and exit. Has either one or two red chests or rarely an item inside. The heart cost can be bypassed with flying upgrades so long as Isaac does not touch the spikes on the sides of the doorway. (This only applies on the way in, with the way back out always causing damage with or without flying upgrades.) If a secret room is next to the Curse room, a second spike door will be spawned allowing access between the two.

Sacrifice Room

Contains nothing but a single spike floor tile. Seems to spawn chests - both locked and unlocked - after walking on the spikes. Random cost of life, sometimes it happens with spending one heart and sometimes more. It is possible to use the Book of Shadows to spend no life but make the chest appear (Note: flying does not affect those spikes). There is also a very rare possibility for the Sacrifice Room to drop "deal with the devil" items, such as Brimstone or the Nail.

Only Works Once

Boss Arena

A special challenge room that seems to always contain an item, at the expense of spawning bosses - much like the normal challenge rooms past The Womb, but found before this point in the game. Visual differences from the normal challenge room are an additional skull at the top of the barred door and a bloody sword on the map. You must either have only 1 heart to go inside (not including soul hearts) or clear all rooms without taking damage.



Library in Cellar.

Gives you 2 books (or sometimes items as well) to choose from. Requires key to unlock door. This room can spawn in The Womb and Utero as well as the usual floors. On rare occasions, there may be an item (confirmed, spawned both Technology 2 and Stigmata) instead of a book on one or both of the pedestals. It is also possible to have the same book spawn on both pedestals. This is thought to be a bug.

Chapel (Secret Room)

File:Chapel room.jpg
A secret room type with glass windows portraying a white cross as well as Isaac's face. Usually contains one half of an eternal heart or a single Fortune Teller machine.

Heart (Secret Room)

Heart room

The secret Heart room.

A secret room type that looks like a room from the Womb and Utero floors. It spawns approximately 7 red hearts around the room.

Trinket (Secret Room)


This Trinket room contained the Child's Heart.

Interior similar to Cellar stage. Contains random trinket lying in the center


  • Spider - Small black spiders that skitter sporadically across the floor. Their movement is difficult to predict, sometimes moving random directions and distances while other times beelining directly toward the player. If they have no direct line of sight to the player, they may stop moving and wait until line of sight is achieved.
  • Trite - Fast, hopping spiders similar to Hoppers, but capable of jumping much further and faster. Some of them replace where Hoppers would be. (Picture of the correct hopping spiders?)
  • Big Spider - Large black spiders that spawn two small spiders when killed.
  • Fat Fly - Pooter that has a body resembling a Boil which fires 2 blood shots at once.
  • Sack - White boil that spawns spiders.
  • Mulliboom - Mulligans with a bomb in their head. Unlike other Mulligans, they will chase instead of fleeing from you, and explode upon impact. (Current bug where they will start to close to you and you cannot get away in time)
  • B. Licker - Larry Jr.-like enemies that separate when one is killed.
  • Gurgle - Gaper that spits explosive shots at close range (like Sloth).
  • Gut - Green boil that spits explosive shots at close range.
  • Walking Boil - Mobile Boil.
  • Walking Sack - Mobile Sack.
  • Walking Gut - Mobile Gut.
  • I.Blob - Clotty that fires in all 8 directions.
  • Eternal Fly - White fly that turns into an attack fly when whatever it's circling is destroyed. Most commonly found circling around Poop, but is also found around certain enemies like (bomb) leeches and hangmen.
  • Holy Leech - White leech with guard fly - explosive (like those found in Sheol).
  • Angelic Baby - Skin-colored, winged Baby that spits a triple shot instead of a regular one. (Looks like a big, angry Guardian Angel)
  • Keeper - Bouncing Greed head. Fires in V pattern similar to SuperPooters. Will steal coins like Greed when player is hit. Amount of coins dropped/stolen from the Player is increased if an Avarice damages the Player in melee.
  • Double Vis - Vis that fires both directions. Has a gash in its back similar to the one on its front.
  • Slide - Blue Poky which stays on one place, but slides fast in a straight line towards Isaac, then returns to its starting position. Unlike regular Pokeys, they won't despawn when the room is cleared from other enemies until you exit and return to the room they were in. (Overall very similar to spike traps from The Legend of Zelda.)
  • Hanger - Flying shop owner on a noose with a guard fly. Fires a triple shot that will steal coins like Greed when the player is hit.
  • Mask + Heart - Big, flying masks that chase you like Knights but are invulnerable. Each mask spawns with a slowly flying heart that spits shots in a cross pattern when in range. A mask dies when its heart is destroyed.
  • Vomit Grimace - Similar to grey statues found in depths except shoots explosive green projectiles like Sloth. It is most commonly found in the Catacombs and Necropolis.
  • Swarmer - A mask surrounded by flies that spawns flies whenever hit. Also periodically spawns flies at random. When destroyed, leaves behind a number of random flies (Pooters, Attack Flies etc.)
  • Psychic Maw - A maw that fires homing tears with a guard fly.
  • Chubber - Fires a Lil Chubby who returns after being thrown. Deals 1 full heart of damage.
  • Mama Guts - Bounces, shooting in 8 directions. Splits into two guts when killed.


  • Cobweb - Slows down player as well as projectiles (Can be destroyed by bombs but leaves mark)
  • Hellfire - An orange version of normal campfires mostly found in the cellar, but occasionally found in other places too. Shoots slow short-ranged projectile at the player.
  • Golden Poop - Similar to the poop obstacle, it is colored yellow and drops around 5 coins or a trinket when destroyed.
  • Poop with Fly Eggs - Poop with an eternal fly orbiting it, when the poop is destroyed, the fly will turn into an attack fly

Bosses and Mini-Bosses

Wrath of the Lamb saw an addition of multiple bosses, many of which being alternates of existing bosses pre-DLC. A full list of these new bosses can be found at the Bosses Added in Wrath of the Lamb page.


An alternative beggar may occasionally spawn in the place of a normal beggar. This beggar takes on a more demonic appearance (horns, gray skin) than his normal counterpart. This demon beggar does not accept money, instead exchanging hearts for items. The "pedestal" items it gives are Deal with the Devil items. Two spiders spawn when blown up.


Curse of Darkness

Removes the map, replacing it with a black room with a question mark in the middle (same as a secret room) for the duration of the whole level.

Curse of the Labyrinth

Curse of the Labyrinth

Curse of the Labyrinth in Necropolis.

Makes the current level much larger, by creating more rooms to walk between. These levels, which are indicated by the suffix "XL" (ex: Catacombs XL), are effectively two stages combined into one, with two treasure rooms and two boss rooms (these are almost always linked, from what I've seen in multiple playthroughs).

  • If the Cellar/Basement is afflicted with this curse, both treasure rooms will be locked and will require a key.
  • If this curse happens on The Depths/Necropolis or The Womb/Utero, first boss rooms will play the same music that plays when fighting Mom or Mom's Heart respectively.
  • Possible that Top Secret Room does not spawn in an XL level

Curse of the Lost

Expands the current floor one size category higher (Basement/Cellar 1 would become the size of Caves/Catacombs 1, Caves/Catacombs 1 becomes Depths/Necropolis 1, etc.)

Also, there is a possibility that there will be no Treasure room on the floor.
