Crow Heart is a trinket added in The Binding of Isaac: Afterbirth † expansion.
- Red heart damage will be taken before soul and black heart damage.
- With bone hearts, red hearts contained within the bone hearts will be taken before regular red heart damage, but the bone hearts will not be fully depleted.
- If Isaac only has half a red heart left, soul and black heart damage will be taken, and bone hearts can be destroyed.
- This is useful for getting into Boss Challenge Rooms when you have soul/black hearts with more than one filled red heart container.
- Red heart damage taken via the trinket affects your Devil/Angel deal chances normally.
- As a result, this trinket basically makes soul/black hearts useless at protecting Devil/Angel deal chances. Consider dropping it until you beat the boss room, and come back for it later for Boss Challenge Room access.
- Reducing your total hearts to one half heart does not activate Scapular unless you no longer have soul and black hearts remaining.
