The spawned door will not disappear when leaving and re-entering the boss room (except in Greed Mode).
Notes[ | ]
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.
Now instead fixes the Angel Room chance at 100%, and the Devil Room chance at 0%.
If the Devil Room has been visited before picking up Eucharist, an Angel Room will not replace it, despite the Angel Room chance displaying 100%.
Synergies[ | ]
Duality: Both Angel and Devil Room doors spawn after every boss, and the selected door will never disappear.
Red Key: Devil rooms can still be spawned via the creation of red rooms.
Filigree Feather: Due to Angel Rooms being guaranteed, a large influx of items can be obtained over time.
