Disambig.png This article is about the chapter. For the object, see Chests. For other uses, see Chest (Disambiguation).

The Chest is one of five final levels in The Binding of Isaac, alongside the Dark Room Dark Room, Added in Afterbirth † The Void The Void, Added in Repentance Corpse Corpse, and Added in Repentance Home Home.

The Chest can be accessed with three methods: Touching the chest dropped by Isaac while having 15►The Polaroid The Polaroid (always dropped by Mom after beating Isaac five times) equipped, or, while in the Cathedral Cathedral, by using Telepills or another item that acts like Telepills, and being sent to the I AM ERROR room, or finding a black market on the Cathedral and going into the beam of light.

Like the Cathedral before it, The Chest consists of only one floor. In The Chest, it is not possible to bomb doors open to skip rooms. The Chest's rooms are mainly filled with bosses and mini-bosses. The boss of the floor is always ???.

The first room in The Chest will automatically contain 4 golden chests. These special chests always contain treasure room items. Rarely, these chests can also be Mega Chests. Additionally, all brown and golden chests spawned in The Chest will always contain Treasure Room Items. This means that a lot of different items can be found in The Chest when clearing rooms with items or effects that raise the chance of spawning chests. This can be useful when trying to complete the collection page. Removed in RepentanceDestroying Slot Machines, Fortune Telling Machines, and all types of Beggars with the exception of a Shell Game Beggar will also spawn items.

After completing The Chest or the Dark Room for the first time, the first room of The Chest will always contain a large golden door, which can be unlocked with either the Key Pieces (combination of 15►Key Piece 1 Key Piece 1 and 15►Key Piece 2 Key Piece 2), 15►Dad's Key Dad's Key, Added in AfterbirthGet out of Jail Free Card Get out of Jail Free Card, or Added in Afterbirth †15►Mr. ME! Mr. ME!, allowing access to Mega Satan.

Notes[]

  • If Isaac gets 15►Key Piece 1 Key Piece 1 and 15►Key Piece 2 Key Piece 2, the key will open the golden gate to fight ???, but if Isaac uses 15►Forget Me Now Forget Me Now, the floor will reset and Isaac won't get both Key Pieces back, making it so that the golden gate won't open again.
  • Added in Afterbirth It is possible to create trapdoors thanks to reward plate (found for example in a secret room). Upon entering them, the floor is restarted. If the large golden door was opened before restarting, it will be closed afterward.
    • This may result in a softlock on a Daily Run to ???, if no other way of opening the door is found.
  • Added in Afterbirth The I AM ERROR room cannot be reached by any method in The Chest and the Dark Room Dark Room.
    • Added in Repentance The I AM ERROR room can be reached by leaving a Crawl Space through an unintended direction or by using Added in Repentance15►Red Key Red Key to get out of the 13x13 boundaries of the map. The room will always contain a portal leading to The Void The Void.
  • Added in Repentance If a Red Chest is placed in the starting room, it will contain a Devil Deal, similar to the Dark Room Dark Room.

Unlockable Achievements[]

  • Dead Boy
    Dead Boy - Complete chapter 6 without taking damage.

Trivia[]

  • The Chest and its boss, ???, are based on the in-game backstory of Isaac locking himself in his toy chest and asphyxiating to death.
  • The sprite appearance of ??? is a reference to Edmund McMillen's Dead Baby games, which are often referenced throughout The Binding Of Isaac.
  • The texture of the floor may have a small chance of showing two small glowing dots that look like eyes.
  • Like in the Dark Room Dark Room, bombing the doors to open them doesn't work on this floor.
  • The shadow cast on the floor most likely resembles Isaac's head while opening the chest.
  • Added in Afterbirth † In The Void The Void, during Delirium's death animation, its boss room switches between different environments, and it always ends with a Chest layout.

Music[]

  • The music for the Chest is titled Sketches of Pain.
