Bag of Crafting will treat double hearts as two heart pickups.Losing Rotten Hearts does not lower the chance of the Angel Room or Devil Room appearing.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.Rotten Hearts are only donated to the Blood Donation Machine after all Red Hearts are depleted.This can be abused to repeatedly pay a half-red heart to step on a spike in a Sacrifice Room, for example. Bone Hearts cannot be broken if filled with at least a Half Red Heart, even if a full heart of damage is taken.Eternal Hearts take half a heart of damage without counting as a hit for Devil Room / Angel Room purposes.Collecting a Soul Heart with half a Black Heart left will complete the Black Heart, and add half a 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).If Isaac's health bar is filled with Soul Hearts, picking up a Black Heart will replace the topmost Soul 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.Unless an item effect specifically states it, a Red Heart always has the chance to be replaced by a Soul, Black, or Eternal Heart.More details on these pickups and how they work can be found here. Each Rotten Heart in Isaac's life bar spawns two Blue Flies upon clearing a room. Rotten Hearts fill up one whole heart container, or the rightmost Red Heart if all of Isaac's heart containers are full, but can only take a half heart of damage each before being depleted (so, for example, two Rotten Hearts will be depleted if a full heart of damage is taken). Takes three hits to deplete and can be refilled with Red Hearts ( and Rotten Hearts), but disappears permanently upon depleting.Ĭannot be filled as ?, Tainted ?, Dark Judas, Tainted Judas, Tainted Forgotten, or Tainted Bethany and only protects against one hit as these characters. If Isaac is only missing half a Red Heart, it will fill that half, and give him half a Soul Heart as well.ĭark Bum and The Jar will not collect this. Humbleing Bundle and Equality! will not double this.įills up a full Red Heart container, but will act as a Soul Heart when no containers are free. It will run away as Isaac moves towards it. Identical to the standard Red Heart, but pulses faster. Like whole Soul Hearts, they can be used to refill a half Black Heart.
Gold Hearts flash when depleted and will temporarily turn enemies golden like Midas' Touch.Ĭan replace regular Soul Heart drops. When that heart is depleted, the Gold Heart will break and 3-8 Coins will be dropped around Isaac. Gold Hearts do not actually add more health, instead forming an outline around the last heart in Isaac's health bar. If Isaac obtains both, the damage will be tripled, reaching 120. If Isaac holds A Missing Page, or has the Missing, the damage dealt will be doubled. When depleted, invokes The Necronomicon effect, dealing 40 damage to every vulnerable enemy in the room. Has a ~4.21% spawn rate in Normal Mode and ~1.69% in Hard Mode. Can only be found by using certain items or encountering certain rooms. If Isaac has no Red Heart containers or Bone Hearts, they are placed in the second half of his first Soul Heart or Black Heart.ĭoesn't appear naturally. Characters that cannot gain Red Heart containers will instead be given a Soul Heart ( Black Heart in the case of Dark Judas and Tainted Judas.) Eternal Hearts are placed in the second half of the last Red Heart container or Bone Heart, even when it is full (the Eternal Heart will overlap with the Red Heart in this case). They will also give a Red Heart container if two are collected on the same floor. When held until the next floor, Eternal Hearts will grant Isaac a Red Heart container. Blood Donation Machines and Devil Beggars will now deplete Isaac's last half or full Red Heart before depleting Soul Hearts. However, donating to a Blood Donation Machine or a Devil Beggar will deplete Red Hearts first as long as Isaac has more than half a Red Heart (a full heart in Womb and beyond). Soul Hearts will be depleted before Red Hearts in most cases. Soul Hearts are not permanent once lost, they cannot be replenished, although new ones may be picked up. Soul Hearts are blue hearts that are added to the end of the health bar. Humbleing Bundle and Equality! can replace this with a Double Heart. Isaac cannot have more Red Hearts than Red Heart containers, but certain Heart pickups can circumvent that limit. Hearts are the standard HP for most characters and can be found in several varieties.
