Crow Heart

Crow Heart is an unlockable trinket added in The Binding of Isaac: Afterbirth †.

Effect[ | ]

Red Heart damage will be taken before Soul Heart, Black Heart, and Rotten Heart damage.
- With Bone Hearts, Red Hearts contained within the Bone Hearts will be taken before regular Red Heart damage.
- If Isaac only has half a Red Heart left / has no Red Hearts left, Soul and Black Heart damage will be taken, and Bone Hearts can be destroyed.

This is useful for getting into Boss Challenge Rooms while maintaining Soul/Black Hearts.
- No longer works as Boss Challenge Rooms now require one heart in total.
Red Heart damage taken via the trinket affects Devil Room/Angel Room chances normally.
- This can be used to voluntarily decrease the Angel / Devil room chance if it has already been accessed in favor of increased chance next floor.
Although Gold Hearts are in front of the HP bar, they will shatter when red heart damage is taken through the trinket.
This trinket is useful when playing as The Forgotten, as it will preserve his Bone Hearts (and Devil/Angel Room chance) until all of his Bone Hearts are empty.
- This trinket does nothing while controlling The Soul.
