Angel Rooms
Angel rooms are the alternative option to the Devil Rooms which can spawn after defeating a boss. Angel rooms can contain a free item from the angel room pool, spirit hearts or eternal hearts. They have a chance to replace devil rooms if the following 2 conditions are met:
If those two conditions are met, any future devil room doors have a 50% chance to be replaced with an Angel Room instead... however that 50/50 devil/angel split can be weighted differently by doing certain things in the game.
Normally the chance to find an Angel room instead of a Devil Room is 50%, however this can be altered by gaining the following bonuses
Players can have a maximum of 2 strong bonuses and 3 weak bonuses on a floor. The combined chances are as follows:
| 0 Strong bonuses | 1 Strong bonus | 2 Strong bonuses | |
|---|---|---|---|
| 0 Weak bonuses | 50% | 75% | 88% |
| 1 Weak bonus | 63% | 81% | 91% |
| 2 Weak bonuses | 72% | 86% | 93% |
| 3 Weak bonuses | 86% | 89% | 95% |
Notes
- Contrary to popular belief, the Bible Tract trinket doesn't allow Angel Rooms to appear after paying for a Devil Deal.
- The bonus from killing a beggar can only be applied once per floor and does not stack.
- The donation machine bonus needs to be donated all in one go and will only apply for the current floor.
- Taking Red Chest items, using the Credit Card, or collecting an item from Krampus doesn't break the conditions for being eligible for Angel Rooms.
- Devil deals taken from a black market will lock in your devil deals and make getting future Angel Rooms impossible UNLESS you use the Afterbirth sacrifice room mechanics to get the 'You feel blessed' buff.
