The I AM ERROR I AM ERROR room is a rare room that isn't connected to any other room on the floor. I AM ERROR rooms contain several items and a trapdoor to the next level (Added in Repentance or a beam of light leading upward during the Ascent), which is the only exit from the room unless Isaac can teleport again.

Room Contents[]

The following room maps were made using Basement Renovator for cleaner viewing.

I AM ERROR rooms always contain a trapdoor to the next level and a unique shopkeeper who can be blown up. Note that all items generated in I AM ERROR rooms will pull from random item pools Removed in Repentance and the trapdoor will always be open, even if there are enemies in the room.

Notes[]

  • Once Isaac arrives at the I AM ERROR room, the only ways out are the trapdoor to the next level or another teleport. As the I AM ERROR room is randomly reached, this could force Isaac to skip Treasure Room Treasure Room and/or Boss Room Boss Room items if they hadn't been picked up before, and if he cannot teleport again.
  • Added in Repentance Once Corrupted Data is achieved (beating Delirium as Tainted Eden Tainted Eden), items that spawn in this room have a chance to be randomized as if affected by TMTRAINER TMTRAINER.
  • If a Crawl Space Crawl Space is spawned in the I AM ERROR room, Isaac will return to the room he was in before being teleported to the I AM ERROR room upon exiting the Crawl Space.
  • Using the trapdoor in the I AM ERROR room can allow Isaac to reach levels not yet unlocked, like Sheol Sheol or Cathedral Cathedral.
  • Removed in Afterbirth Using the trapdoor in Chest Chest or the Dark Room Dark Room will restart the level, similar to the effect of the Forget Me Now Forget Me Now, and as of patch 1.05, the floor will generate a different layout upon restarting. The door to Mega Satan will be locked if it was previously opened.
  • The chests present in the I AM ERROR room from Chest Chest and Dark Room Dark Room always contain items.
  • Using the Rune of Jera Rune of Jera in most of these room configurations can allow Isaac to summon and pick up a large amount of items, making the item especially effective in this room.
  • If a Red Chest teleports Isaac to a Devil Room Devil Room or Angel Room Angel Room from an I AM ERROR room, exiting the room will return him to the room he was in before entering the I AM ERROR room.
  • Entering the I AM ERROR room from Womb Womb/Utero Utero/Scarred Womb Scarred Womb II will randomly result in a trapdoor or a beam of light. Isaac may have to end his run early in the Cathedral Cathedral/Sheol Sheol.
  • It is probably not a good idea to go to the I AM ERROR room on Depths Depths/Necropolis Necropolis/Dank Depths Dank Depths II, because Isaac will be unable to pick up The Polaroid The Polaroid/The Negative The Negative, and can not go to either Chest Chest or Dark Room Dark Room, having to end his run in Sheol Sheol or Cathedral Cathedral.
    • Reaching another I AM ERROR room in the above-mentioned levels would allow continuing the run beyond them, even lacking the prerequisite items.
    • Note that the 12th reward and onward in a Sacrifice Room Sacrifice Room has a 50% chance to send Isaac to Dark Room Dark Room. This may be useful if an I AM ERROR room locked Isaac out of The Negative The Negative.
    • Added in Repentance This rule also applies to Isaac when trying to reach an alternate floor from a main floor (Downpour Downpour II from Basement Basement II, etc.). The I AM ERROR room will always send him to a regular floor (Basement Basement II to Caves Caves I, etc.) and Isaac will not be able to pick up the necessary progression items needed to reach Corpse Corpse.
    • Added in Repentance This also applies to reaching Home Home. The I AM ERROR rooms of Depths Depths II, etc., will instead send Isaac to Womb Womb I, etc., and he will not be able to enter the Strange Door.
  • Added in Afterbirth There is a rare Closet room in Depths Depths and Necropolis Necropolis containing an I AM ERROR shopkeeper. This is not an I AM ERROR room, and can be exited normally.
  • Added in Afterbirth There is a Super Secret Room Super Secret Room that looks like an I AM ERROR room. This is not an I AM ERROR room, and can be exited normally.

Trivia[]

  • The I AM ERROR room is a reference to an infamous quote in the NES game Zelda II: The Adventure of Link, where a citizen from Ruto introduces himself with the sentence "I AM ERROR".
  • Due to the relative difficulty involved in accessing this room, and the name of the room itself, it could be a failsafe.

Bugs[]

Bug Bug! If isaac enters an I AM ERROR room on in the first room of the first floor (possible with Eden Eden), and have not entered any rooms yet, using Added in AfterbirthGlowing Hour Glass Glowing Hour Glass will send him back to an identical starting room, with all of his starting items missing, including the Glowing Hour Glass
