Hearts

This article is about the pickup. For other uses, see Heart (Disambiguation).

**Hearts** are the standard HP for most characters and can be found in several varieties. Isaac cannot have more Red Hearts than Red Heart containers, but certain Heart pickups can circumvent that limit.

## Notes

*More details on these pickups and how they work can be found here.*

* Unless an item effect specifically states it, a Red Heart always has the chance to be replaced by a Soul, Black, or Eternal Heart.
* Red Heart pickups created by item, card, or pill effects can be forced to be spawned as Black or Eternal Hearts instead by using the item, card, or pill in a relevant Super Secret Room.
* If Isaac's health bar is filled with Soul Hearts, picking up a Black Heart will replace the topmost Soul Heart.
	+ If Isaac's health bar is filled up to 11 1/2 (Soul/Black) Hearts with the last one being half a Black Heart, picking up a Black Heart will fill that one and convert a full Soul Heart to a Black Heart (therefore adding half a Black Heart and converting a Soul Heart).
	+ Collecting a Soul Heart with half a Black Heart left will complete the Black Heart, and add half a Soul Heart. The reverse is also true.
* Eternal Hearts take half a heart of damage without counting as a hit for Devil Room / Angel Room purposes.
* Bone Hearts cannot be broken if filled with at least a Half Red Heart, even if a full heart of damage is taken. This can be abused to repeatedly pay a half-red heart to step on a spike in a Sacrifice Room, for example.
* Rotten Hearts are only donated to the Blood Donation Machine after all Red Hearts are depleted.
* If Rotten Hearts have not been unlocked yet, any room layouts containing them (including the Corpse themed Super Secret Room) will instead contain Half Red Hearts.
* Losing Rotten Hearts does not lower the chance of the Angel Room or Devil Room appearing.
* will treat double hearts as two heart pickups. Blended Hearts will be treated as a Soul Heart and a Red Heart.
* The probabilities in the table refer to the kind of heart that is generated by the game when a heart is spawned with a sub-type of 0 (i.e. a random heart).

## Trivia

* There are unused graphics for Half Soul Hearts and Half Black Hearts that are never seen in-game.
	+ Half Soul Hearts were eventually added to the game as an unlockable.
* Booster Pack #5 made Scared Hearts beat faster, making them slightly easier to spot. This was from this Steam Workshop mod by piber20.
* Gold Hearts' appearance was changed in Booster Pack #5.
* Most items that grant Black Hearts upon being picked up say "evil up" in their description.
* Immortal Hearts were a heart type present in the original *Antibirth* mod, but were not added to *Repentance*.
* Blended hearts were a feature in the Community remix mod for the original *The Binding of Isaac*.
