(first time editing but I thought it was worth noting that the eternal heart will change to a full heart when completing a floor (including by an item such as Forget Me Now))

'''Hearts''' are [[Pick Ups]] that replenish [[Isaac]]'s [[Stats/Health|health]]. If Isaac runs out of both Red and Soul Hearts he will die and view his [[Isaac's Last Will|Last Will]], unless he has [[Dead Cat]], [[Ankh]] or [[1UP]].
'''Hearts''', or HP, is the player's life force; running out will cause the player to die, losing a life or ending the game.
 
   
  +
If Isaac enters a room with a half Red Heart or less, a pool of urine (blood in [[Eve]]'s case) will be formed under him. 
Players start the game with a specific number of "heart containers", the number varying on the character chosen.
 
   
==Heart Containers==
+
==Red Hearts==
  +
[[File:Half heart.png]] [[File:Full heart.png]]
Each Heart Container holds one full heart of HP, taking damage will empty one-half or one full heart container.
 
   
  +
===Heart Containers===
The maximum number of heart containers can be increased by consuming an HP up item or pill, up to a maximum of 12. Any heart containers found past that point can be spent at devil rooms, but not filled with hearts or half-hearts.
 
  +
In order for Isaac to pick up Red Hearts, he must have Heart Containers that can be gained from a number of "Health Up" collectables or through completion of an Eternal Heart. Most characters also begin the game with at least one Heart Container, with the exception of [[???]], who is unable to gain Heart Containers at all, instead converting them into single Soul Hearts. Upon taking damage, Isaac will lose Red Hearts and be left with unfilled Heart Containers, which can then be refilled by the collection of Red Hearts.
   
  +
Since the Eternal Edition, if the player gets more than 12 Heart Containers, their icons will shrink, allowing for more to be visible on the health bar. However, it's not possible to have more than 16 Heart Containers, as any HP up earned at that time will be turned into a Soul Heart instead of a Heart Container.
Empty heart containers can be filled using hearts or half-hearts.
 
   
Heart containers can be spent like currency in the Devil Room and can be emptied for cash at the blood donation machine.
+
Heart Containers can be lost from the use of a [[Pills|Health Down Pill]], certain Collectables, or being traded to the [[Devil Room|Devil]].
   
  +
1+1 Free Heart fills two heart containers.
==Regular hearts==
 
Regular heart pickups are divided into Half Hearts and Full Hearts. These have about an equal chance of spawning.
 
   
===Half-Hearts===
+
==SouI Hearts==
 
[[File:Soul heart.png]]
These refill 1/2 of one heart container and can only be claimed if the player has less than full HP. These are common and can be found in a number of places.
 
   
  +
'''Soul Hearts''' look similar to regular hearts but are blue with a gray outline. They are a rarer form of Heart which may replace nonspecific Red Hearts, or can be found in Shops. They have a high chance of spawning when a [[Rock#Tinted Rock|Tinted Rock]] is blown up.
[[File:Half_heart.png]]
 
   
  +
Soul Hearts function as a form of armor for Isaac, absorbing damage that he takes so that he does not lose any Red Hearts. Once a Soul Heart is obtained, most damage removes Soul Hearts until their supply is depleted. Each Soul Heart adds a full Heart and can take a full Heart's worth of damage before being lost. Soul Hearts may be increased beyond the maximum visible level of Red Hearts and will still be counted even though they are not shown. The last half Soul Heart Isaac has will absorb any amount of damage while breaking, so taking a full Heart of damage with one half Soul Heart will not affect Isaac's Red Hearts.
===Full Hearts===
 
These will refill 1 full heart container and can be claimed when the player has at least 1/2 heart missing, though this will cause half of the heart to go to waste. In addition to being found where normal hearts are these can also be purchased in shops.
 
   
  +
Additionally, three Soul Hearts may occasionally be traded in the Devil Room in exchange for a Collectable (for [[???]], all devil deals are traded for soul hearts).
Full Hearts cost 3 coins in the shop, 2 when on sale.
 
   
  +
A Heart has a chance of spawning as a Soul Heart based on these rules:
[[File:Full_heart.png]]
 
  +
# 1/10 chance
  +
# 1/6 chance if playing as [[Eve]] (16.25%)
  +
# 1/10 if holding the [[Mom's Pearl]] trinket
  +
# 1/2 if holding the [[Mitre]]
  +
Note that the extra chances for a Soul Heart to spawn are consecutive rather than additive, so (if not Eve) with Mom's Pearl, Isaac's chance would be 1 - (0.9 * 0.9) = 19% (rather than 20%) and with the Mitre his chance would be 1 - (0.9*0.5) = 55% (rather than 60%)
   
 
==Eternal Hearts==
 
[[File:Eternal.png]]
   
  +
'''Eternal Hearts''' are a type of Heart introduced in ''[[The Binding of Isaac: Wrath of the Lamb|Wrath of the Lamb]]''. They act as a Half Red Heart until Isaac picks up a second one or moves onto the next floor (also works when the [[Forget Me Now]] is used), in which case it will turn into a filled Heart Container. Eternal Hearts alone are not enough to prevent death. If Isaac has an Eternal Heart but no Red Hearts, he will still die if he loses all of his Soul Hearts. However, the Eternal Heart will remain if Isaac comes back to life with Dead Cat, Ankh or 1UP.
===HP-Ups===
 
A number of treasures in game will increase your Max HP.
 
   
  +
Eternal Hearts can replace nonspecific Heart Drops with a 1/50 base chance or be granted by obtaining certain [[Collectable Items]]. They can also be found in the [[Cathedral]]-themed [[Super Secret Room]]. In addition, any nonspecific Hearts Spawned in that room will be Eternal.

*Odd Mushroom (may have random side effects)
 
*Super Bandage (also adds 2 Soul Hearts)
 
*Health Up Pill (does not fill the added heart)
 
*Strength Tarot Card (Temporary)
 
+2 Max HP
 
*Bucket of Lard (empty, speed decrease)
 
*Raw Liver (Full heal, range decrease)
 
   
  +
It is possible to lose Eternal Hearts by getting hurt by enemies and [[Blood Donation Machine]]s (including [[IV Bag]]). Blood Donation Machines take Eternal Hearts before any other type of hearts, but getting hurt by an enemy takes Soul Hearts first, then Eternal Hearts then Red Hearts. Unlike Soul Hearts, taking a full Heart of damage with just an Eternal Heart and Red Hearts will remove the Eternal Heart and half of a Red Heart, not just the Eternal Heart.
==Soul Hearts==
 
Soul Hearts are a rarer form of heart that may randomly appear instead of full hearts or can be found from drops/shops and won from slot machines and shell games in the place of hearts respectively.
 
   
  +
* If you lose an Eternal Heart by taking damage from other enemies, the chance of spawning Devil Room will be heavily decreased. This may indicate that Eternal Hearts are actually treated as Red Hearts and thus explain why they are depleted first when using Blood Donation Machines.
Soul Hearts function as a form of armor for the player, absorbing damage that they take so that the player does not lose any HP. Once a soul heart is obtained, all normal damage removes soul hearts until their supply is depleted. Each soul heart adds a full container and can take a full heart's worth of damage before being lost.
 
   
  +
If you go into a [[Devil Room]] with no soul hearts and an Eternal Heart, and take a deal with the devil that doesn't kill you, you will lose the eternal heart. If Isaac goes into a [[Devil Room]] and he has an eternal heart and 2 or more soul hearts, and takes a deal costing two red hearts, Issac may die instantly.
Additionally, three soul hearts may occasionally be spent in the Devil Room to purchase an item.
 
 
Soul Hearts may be increased beyond the maximum ''visible'' level of HP and will still be counted even though they are not shown.
 
 
Soul Hearts in the shop cost 5 coins, 3 when on sale.
 
 
[[File:Soul_heart.png]]
 
 
==Eternal Hearts==
 
   
  +
[[Magneto]] will only attract Eternal Hearts when Isaac has unfilled Heart Containers.
In the expansion [[The Binding of Isaac: Wrath of the Lamb]], these special hearts can be received by any means that would otherwise yield a regular or soul heart but are rarer than Soul Hearts. Eternal Heart can also be found in the Chapel room. Acts as a soul heart until two halves become a whole, or the player moves onto the next floor (Also works when an item is used to achieve this effect such as [[Items#Forget Me Now|Forget Me Now]]), turning it into a permanent heart container. The Prayer Card generates half of an Eternal Heart every time it is used. Fate item also adds an eternal heart. Eternal Hearts alone are not enough to prevent death. If you have no regular hearts (for example, playing with [[???]]) and have an Eternal Heart you will still die if you lose all Soul Hearts.
 
   
  +
In the Eternal Edition, if you obtain 7 or more total heart containers purely from eternal hearts in a single run (either from more to the next floor with an eternal heart or combining 2 eternal hearts), your character will be tinted white, given flight for the rest of the run, and you will be given the achievement Eternal Life.

Hearts are Pick Ups that replenish Isaac's health. If Isaac runs out of both Red and Soul Hearts he will die and view his Last Will, unless he has Dead Cat, Ankh or 1UP.

If Isaac enters a room with a half Red Heart or less, a pool of urine (blood in Eve's case) will be formed under him. 

Red Hearts

Half heart Full heart

Heart Containers

In order for Isaac to pick up Red Hearts, he must have Heart Containers that can be gained from a number of "Health Up" collectables or through completion of an Eternal Heart. Most characters also begin the game with at least one Heart Container, with the exception of ???, who is unable to gain Heart Containers at all, instead converting them into single Soul Hearts. Upon taking damage, Isaac will lose Red Hearts and be left with unfilled Heart Containers, which can then be refilled by the collection of Red Hearts.

Since the Eternal Edition, if the player gets more than 12 Heart Containers, their icons will shrink, allowing for more to be visible on the health bar. However, it's not possible to have more than 16 Heart Containers, as any HP up earned at that time will be turned into a Soul Heart instead of a Heart Container.

Heart Containers can be lost from the use of a Health Down Pill, certain Collectables, or being traded to the Devil.

1+1 Free Heart fills two heart containers.

SouI Hearts

Soul heart

Soul Hearts look similar to regular hearts but are blue with a gray outline. They are a rarer form of Heart which may replace nonspecific Red Hearts, or can be found in Shops. They have a high chance of spawning when a Tinted Rock is blown up.

Soul Hearts function as a form of armor for Isaac, absorbing damage that he takes so that he does not lose any Red Hearts. Once a Soul Heart is obtained, most damage removes Soul Hearts until their supply is depleted. Each Soul Heart adds a full Heart and can take a full Heart's worth of damage before being lost. Soul Hearts may be increased beyond the maximum visible level of Red Hearts and will still be counted even though they are not shown. The last half Soul Heart Isaac has will absorb any amount of damage while breaking, so taking a full Heart of damage with one half Soul Heart will not affect Isaac's Red Hearts.

Additionally, three Soul Hearts may occasionally be traded in the Devil Room in exchange for a Collectable (for ???, all devil deals are traded for soul hearts).

A Heart has a chance of spawning as a Soul Heart based on these rules:

  1. 1/10 chance
  2. 1/6 chance if playing as Eve (16.25%)
  3. 1/10 if holding the Mom's Pearl trinket
  4. 1/2 if holding the Mitre

Note that the extra chances for a Soul Heart to spawn are consecutive rather than additive, so (if not Eve) with Mom's Pearl, Isaac's chance would be 1 - (0.9 * 0.9) = 19% (rather than 20%) and with the Mitre his chance would be 1 - (0.9*0.5) = 55% (rather than 60%)

Eternal Hearts

Eternal

Eternal Hearts are a type of Heart introduced in Wrath of the Lamb. They act as a Half Red Heart until Isaac picks up a second one or moves onto the next floor (also works when the Forget Me Now is used), in which case it will turn into a filled Heart Container. Eternal Hearts alone are not enough to prevent death. If Isaac has an Eternal Heart but no Red Hearts, he will still die if he loses all of his Soul Hearts. However, the Eternal Heart will remain if Isaac comes back to life with Dead Cat, Ankh or 1UP.

Eternal Hearts can replace nonspecific Heart Drops with a 1/50 base chance or be granted by obtaining certain Collectable Items. They can also be found in the Cathedral-themed Super Secret Room. In addition, any nonspecific Hearts Spawned in that room will be Eternal.

It is possible to lose Eternal Hearts by getting hurt by enemies and Blood Donation Machines (including IV Bag). Blood Donation Machines take Eternal Hearts before any other type of hearts, but getting hurt by an enemy takes Soul Hearts first, then Eternal Hearts then Red Hearts. Unlike Soul Hearts, taking a full Heart of damage with just an Eternal Heart and Red Hearts will remove the Eternal Heart and half of a Red Heart, not just the Eternal Heart.

  • If you lose an Eternal Heart by taking damage from other enemies, the chance of spawning Devil Room will be heavily decreased. This may indicate that Eternal Hearts are actually treated as Red Hearts and thus explain why they are depleted first when using Blood Donation Machines.

If you go into a Devil Room with no soul hearts and an Eternal Heart, and take a deal with the devil that doesn't kill you, you will lose the eternal heart. If Isaac goes into a Devil Room and he has an eternal heart and 2 or more soul hearts, and takes a deal costing two red hearts, Issac may die instantly.

Magneto will only attract Eternal Hearts when Isaac has unfilled Heart Containers.

In the Eternal Edition, if you obtain 7 or more total heart containers purely from eternal hearts in a single run (either from more to the next floor with an eternal heart or combining 2 eternal hearts), your character will be tinted white, given flight for the rest of the run, and you will be given the achievement Eternal Life.

Finding Hearts

Nonspecific Hearts

These Hearts have a chance to be Red, Soul or Eternal.

Furthermore, the Child's Heart Trinket adds an additional 10% chance to spawn a heart upon clearing a room, as well as an extra 67% chance to find them in Chests.
