Eucharist is an unlockable passive item added in The Binding of Isaac: Afterbirth †.
- An Angel Room Door will always spawn after every boss fight.
- Devil Rooms will no longer appear.
- The spawned door will not disappear when leaving and re-entering the boss room.
- Eucharist applies two effects. Like Goat Head, it fixes the Devil Room chance at 100%, which forces an Angel/Devil Room to spawn whenever it can; it also fixes the Angel Room chance at 100%, so the game always chooses an Angel door over a Devil door.
- Duality: Both Angel and Devil Room doors spawn after every boss, and the selected door will never disappear.
- This is the only way to encounter Devil deals while possessing Eucharist.
- A eucharist is a Christian rite in which bread and wine are consecrated on an altar and consumed thereafter.
