Angel Room

Angel Room door

Angel Rooms feature an angel and several free items: the divine equivalent of the Devil Room. Every time the Devil Room is spawned/entered, there's a chance for it to be replaced by the Angel Room if certain conditions are met. After beating the Dark Room Dark Room or The Chest The Chest once, an Angel can be awoken by planting a bomb near the statue (or destroying it with 15►Leo Leo or similar items). This will begin an angel boss fight and allow Isaac to pick up 15►Key Piece 1 Key Piece 1 or 15►Key Piece 2 Key Piece 2. Both pieces are needed to get through the Golden Door in The Chest or the Dark Room to fight Mega Satan.

Variations[edit | edit source]

The following room maps were made using Basement Renovator for cleaner viewing. Note that, unlike Devil rooms, items in Angel rooms cost nothing to take, but if there are multiple items, taking one will cause the others to disappear.

If an Angel Room appears upon defeating Mom's Heart or It Lives, it will only contain a beam of light leading to The Cathedral.
Added in Afterbirth Angel Rooms that appear upon defeating It Lives no longer contain beams of light and instead have normal Angel Room contents.

Conditions to Make Angel Rooms Appear[edit | edit source]

For the player to have a chance to get an Angel Room after killing a boss (or with a Joker Joker card / Red Chest teleport), some conditions must be met:

  • 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 Card Credit Card, using Added in Afterbirth †15►Coupon Coupon, 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.

Added in Afterbirth 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 Joker Joker 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:

Condition Chance Bonus
Base chance 50%
Holding Rosary Bead Rosary Bead 50%
Donating 10 coins to the Donation Machine on the current floor 50%
Holding 15►Key Piece 1 Key Piece 1 25%
Holding 15►Key Piece 2 Key Piece 2 25%
Killing a Devil Beggar, Key Master, or Shell Game Beggar on the current floor **
  • Added in Afterbirth Killing Key Masters and Shell Game Beggars no longer applies the bonus.
25%
Donating to a Beggar until it pays out with an item on the current floor **
  • Making a Key Master, Bomb Bum, or Shell Game Beggar pay out does not apply the bonus.
25%
Added in Afterbirth 10%
Donating to a Devil Beggar until it pays out with an item on the current floor **
  • Added in Afterbirth If this coin flip succeeds, a Devil room will be generated regardless of the above coin flips.
25%
Added in Afterbirth 10%
Added in Afterbirth "You feel blessed!" fortune in the Sacrifice Room of the current floor
  • If the "You feel blessed!" fortune appeared on the 3rd sacrifice, the chance will be 15%.
  • If the "You feel blessed!" fortune appeared on the 5th sacrifice, the chance will be 50%.
  • If both "You feel blessed!" fortunes appeared, the chance will be 65%.
15/50/65%
Holding Added in Afterbirth †15►Eucharist Eucharist Guaranteed
Added in Repentance First successful generation after not entering the first Devil Room seen on a run Guaranteed

** These conditions share the same "coin flip chance" in Rebirth.

Examples[edit | edit source]

If Isaac meets the prerequisites and has 15►Key Piece 1 Key Piece 1 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 -- take note that the result is not simply the sum of the coin flip probabilities 50% + 25% for 75%.

If Isaac meets the prerequisites, has 15►Key Piece 1 Key Piece 1, 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.

Notes[edit | edit source]

  • The highest Angel Room chance is 95.25% in Rebirth and 98.34% in Afterbirth (with the Sacrifice Room blessings).
    • Added in Afterbirth †15►Eucharist Eucharist guarantees that an Angel Room will spawn on every possible floor.
  • It is possible to be teleported to an Angel Room from a Joker Joker card or a Red Chest.
    • Added in Afterbirth It is also possible to teleport there from the 6th sacrifice of a Sacrifice Room.
  • If an Angel Room spawns after the player defeats Mom's Heart or It Lives, instead of items or pickups, a beam of light will appear. Touching this beam of light will take the player to the Cathedral. The Angel can still be awoken by destroying the statue in this room. The beam of light will disappear for the duration of the fight.
    • Added in Afterbirth Angel Rooms that spawn after Isaac defeats It Lives will be normal Angel Rooms with items or pickups.
  • The Rock behind the Angel can rarely be a Tinted Rock.
  • Added in Afterbirth A Troll Bomb can sometimes appear behind the angel statue, blowing it up. If the Angel fights have been unlocked, this will begin the boss fight if the player is not careful or quick enough to move the bomb.
  • Added in Afterbirth † Two angel statues can appear in the same room, allowing Isaac to fight both Uriel and Gabriel. It is possible to get both Key Pieces if Isaac awakes and fights each of them one by one; however, fighting both at once will only spawn one Key Piece corresponding to the last defeated angel.
  • Contrary to popular belief, the Bible Tract Bible Tract doesn't allow Angel Rooms to appear after paying for a Devil deal.
