Binding of Isaac: Rebirth Wiki
(in Afterbirth † and Repentance)

The debug console is accessible in The Binding of Isaac: Afterbirth † and The Binding of Isaac: Repentance. It is an extremely useful way to verify a particular game mechanic, explore a seed, test launch options, or test various things about the game. Or, if you are a mod developer, you can use it to quickly test various things in your mods. It is inaccessable on Console Editions.

(except in Repentance) The debug console is only accessible if one or more mods are enabled. If you don't have any mods to enable, download one from Steam Workshop, or simply create an empty folder in your mods directory. Note that achievements will be disabled if Boss Mom ingameMom has not been defeated on the savefile, and consequently unlocks will not happen, donation machines can't be filled nor will the item collection page record anything. While many "enable debug console" mods exist on Steam Workshop, these do not explicitly enable the console or are required to enable it. ANY mod will enable the console, regardless of what the mod is named.

(in Repentance) The debug console is only accessible by editing options.ini in the configuration directory and setting the EnableDebugConsole option to 1.

The directory which contains the game data and mods directories varies by OS and, where appropriate, compatibility layer.

  • Windows: C:\Users\%username%\Documents\My Games
    • Windows 11: Searching for Users folder may be required first
  • Linux native: ~/.local/share
  • Linux, via Proton: /path/to/Steam/steamapps/compatdata/250900/pfx/drive_c/users/steamuser/Documents/My Games
  • Mac OS native: ~/Library/Application Support/Binding of Isaac Rebirth

The directory names within that directory are as follows:

  • Configuration & save data:
    • Binding of Isaac Afterbirth+
    • binding of isaac afterbirth+ (Linux native)
    • Binding of Isaac Repentance
  • Mods:
    • Binding of Isaac Afterbirth+ Mods
    • binding of isaac afterbirth+ mods (Linux native)

g p22
giveitem k1
giveitem c6
g k45
Gives items, trinkets, cards, and pills.

Ids are prefixed with c for items, t for trinkets, p for pill effects, and k for cards. Runes and other pocket items use card ids.

goto d.10
goto s.error.21
goto 6 6 0
Teleports Isaac to room layouts which are possible to generate in the current floor.
  • The "d.[number]" syntax means a "normal" room with the corresponding number as a variant.
  • The "s.[type].[number]" syntax means a special room of the specified type and variant.
  • The "[number] [number] [number]" syntax means to go to the existing room at the specified coordinates. The first number is the X coordinate, the second number is the Y coordinate, and the third number is the dimension, which corresponds to the Dimension enum.

The first two goto formats will put Isaac in the GridRooms.ROOM_DEBUG_IDX (-1) room. Attempting to enter a room that does not exist will print the message "Error changing room." to the console.

gridspawn 1000
gridspawn 1494
gridspawn 9000
gridspawn 9100
gridspawn 1000 28

(in Repentance) forceroom
forceroom s.boss.1010
Allows to set any room as "forced room". Said room gets weight of 1000, making it easier for it to appear on floor with reseed command. There are many situations where it would not work though (e.g. if room has lots of disabled doors or difficulty does not allow it to appear).
(in Repentance) giveitem2


giveitem2 c105
g2 ipecac
Same as giveitem but for a secondary character such as Esau.

Trivia[ | ]

  • (in Repentance) In Repentance, going to non-standard stages will crash the game.
  • (except in Repentance) In Afterbirth+, going to non-standard stages will crash the game, with the exception of stage 13. It consists of 2x1 vertical rooms that have doors that only sometimes close, minimal enemies (usually a few of the same type), and uses CavesCaves background. The music is a single layer of either the ??????, CellarCellar, BasementBasement or the Burning BasementBurning Basement music, and only plays when enemies are in the room. The boss is always Boss The Duke of Flies ingameThe Duke of Flies, and no trapdoor or items spawn when the boss is defeated.
    • Stage 13a is the same, but with DepthsDepths background. The boss is always Boss Monstro II ingameMonstro II.
    • Stage 13b is the same, but with WombWomb background. The boss is always Boss The Duke of Flies ingameThe Duke of Flies.
    • The enemy spawn patterns are the same as the waves in Greed mode, suggesting that this stage is used to store the waves in the game.
    • The name display while holding Tab on PC/Back on Xbox 360/Touchpad or L2 on PS4/Minus on Switch will show up their respective overlay's stage name, but without the I or II, e.g. Normally it's Caves II, but in this stage is referred to only Caves, just like CathedralCathedral, SheolSheol, ??????, ChestChest, Dark RoomDark Room and The VoidThe Void, i.e Chapters 4.5 and above.
  • (except in Repentance) Entering "stage 8" in Greed or Greedier mode will grant access to The VoidThe Void. The rooms have random backdrops and the music is the same as The Void in regular mode, but the boss is Boss Ultra Greed ingameUltra Greed and will drop the Final Boss Chest. Entering The Chest will play the final ending instead of ending 18 or 19.
  • (in Repentance) In Greed/Greedier Mode, there are odd, secret additional stage layouts that use Stage IDs further than 8, and are variants of existing floors. Some are based off the new Repentance path's floors. Stage 8 is a blank floor with no walls and music, Stage 9 is the Ultra Greed floor but with ??????'s doorways, stage 10 is the Ultra Greed floor but with a sick-green and cleaner version of DrossDross and stage 11 is the Ultra Greed floor with the backdrop of MausoleumMausoleum.
    • Any further values will crash the game.
    • There are some that use the 'a' and 'b' ID variation, and are alternate versions of the existing but some are of the hidden floors.
      • Stage 5a will have the SheolSheol backdrop with a light effect coming from above, and entering Stage 5b is the same as the Stage 5a, but the backdrop's walls can be a little bit brighter, or as dim as the original Stage 5's.
      • Stage 6b and 7b will have the The ShopThe Shop/Ultra GreedUltra Greed backdrop with a warmer color than normal Stage 6 and 7. Stage 6c and 7c will have the The ShopThe Shop/Ultra GreedUltra Greed backdrop but with a blue tint.
      • Stage 8a is the same Stage 8, but can have the floor of the BasementBasement.
      • Stage 8b can be the same Stage 7b but can sometimes come with no music at all.
      • Stage 9a comes with a random backdrop and the music of The VoidThe Void, but it has the doorways of ??????. The Final Boss Chest will play ending 20 instead of Ending 18 or 19 depending on the mode selected.
      • Stage 9b comes with a brownish version of DownpourDownpour's backdrop. It has the doorways of ??????.
      • Stage 10a has the backdrop of the MinesMines.
      • Stage 10b comes with a reddish version of the AshpitAshpit's backdrop.
      • Stage 11a has the backdrop of GehennaGehenna.
      • Stage 11b comes with a reddish version of CorpseCorpse's backdrop.
  • Attempting to give yourself all the items using "giveitem *" will print the message "What are you trying to do?" to the console and will give nothing.
  • Monster champion types go up to 48590, with anything beyond the 24 used types resulting in a monster that has double (maximum) HP, no other special abilities and often exotic color palettes not normally seen. Any higher will crash the game.
    • (in Repentance) Champions types above the 26 defined ones are mostly invisible and have no clear upper number, but may cause a crash at any time.

Bugs[ | ]

Bug Bug! If a champion is spawned via the "spawn" command, it will have the same amount of health as the non-champion version of that monster, unless the spawned champion variant has decreased amount of health.
Bug Bug! If the player has debug 10 enabled and starts the sequence to begin the Dogma fight, Dogma will instantly die without continuing the sequence, softlocking Isaac in the room without returning control to the player. This is fixed after exiting and continuing the game.
Bug Bug! (in Repentance) Using the "rewind" command removes all broken hearts on Character The Soul (Character) iconThe Soul if there are any.
Bug Bug! Debug Console may rarely break, and will not turn off.
Bug Bug! (in Repentance) Using debug 12 during the Collectible Knife Piece 2 iconKnife Piece 2 sequence in Mines/Ashpit II will crash the game.
