Conditions to Make Angel Rooms Appear[edit | edit source]
- A Devil Room door has spawned on any previous floor.
- No items from the Devil Room or black market have been paid for with health throughout the run.
- Taking red chest items, using Credit CardConverts all items in the Shop or Devil Room into pickups or items on pedestals, allowing them to be picked up for free., using CouponUpon use, makes a random item from a shop, devil deal, or black market free., or collecting an item from Krampus doesn't count.
- Even though it technically doesn't cost any health, taking a devil deal with The Lost will still prevent Angel Rooms from appearing.
Sacrifice Room Exception[edit | edit source]
- On the 3rd and 5th sacrifice in a sacrifice room, there is a 66% chance that the player will receive the "You feel blessed!" effect. This will increase the chances of the Angel Room spawning even if the previous conditions have not been met.
- On the 6th sacrifice in a sacrifice room, there is a 33% chance that the player will be teleported to the Angel Room if they haven't already visited or opened the Devil Room for that floor. This will occur even if the previous conditions have not been met.
Angel Room Generation Chance[edit | edit source]
The selection between Angel Room and Devil Room is made upon opening the door after defeating the floor's boss (or upon teleporting to the room using a JokerTeleports you to the Devil Room or Angel Room. card or a red chest).
The game makes a series of coin flips to determine if an Angel Room will appear or not. If one of these coin flips succeeds, an Angel Room is generated (except for the Devil beggar coin flip). If all the coin flips fail or no coin flips are done, a Devil Room is generated. Satisfying certain conditions gives additional coin flips with varying probabilities:
|Holding Rosary BeadIncreases the chance of Angel Rooms appearing. Increases the chance to find The Bible in the Library and Shop.||50%|
|Donating 10 coins to the donation machine on the current floor||50%|
|Holding Key Piece 1Combined with Key Piece 2, unlocks the golden gate in the starting room of The Chest and Dark Room to fight Mega Satan.||25%|

|Holding EucharistAn Angel Room door will always spawn after every boss fight, excluding the first floor and floors after Utero II/Womb II.||Guaranteed|

Examples[edit | edit source]
If Isaac meets the prerequisites and has Key Piece 1Combined with Key Piece 2, unlocks the golden gate in the starting room of The Chest and Dark Room to fight Mega Satan. with him, the game will make two coin flips to determine if he gets an Angel Room or not. The first coin flip has a 50% success chance and the second one has a 25% success chance. Isaac will only get a Devil Room if both coin flips fail, and he will get an Angel Room if one of the coin flips succeeds. The chance of failure is 0.5 * 0.75 = 0.375, which means the chance of success is 1 - 0.375 = 0.625. Thus, Isaac has a 62.5% chance to get an Angel Room.
If Isaac meets the prerequisites, has Key Piece 1Combined with Key Piece 2, unlocks the golden gate in the starting room of The Chest and Dark Room to fight Mega Satan., and has destroyed a Devil beggar on the current floor, the chance to fail all coin flips (and get a Devil Room) become 0.5 * 0.75 * 0.75 = 0.28125, which means that the chance of success is 1 - 0.28125 = 0.71875. Thus, Isaac has a 71.875% chance to get an Angel Room.
