The 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, which is the only exit from the room unless the character 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 and (except in Repentance)the trapdoor will always be open, even if there are enemies in the room.

Notes

  • Once a character 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 the player to skip Treasure Room and/or Boss Room items if they hadn't been picked up before, and if the character cannot teleport again.
  • (in Repentance) Once Corrupted Data is achieved (beating Delirium as Character Tainted Eden iconTainted Eden), items that spawn in this room have a chance to be randomized as if affected by (in Repentance)Collectible TMTRAINER iconTMTRAINER.
    • If a 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 a character to reach levels not yet unlocked, like Template:Stage or Template:Stage.
  • (in Rebirth) Using the trapdoor in Template:Stage or the Template:Stage will restart the level, similar to the effect of the Collectible Forget Me Now iconForget Me Now, and as of patch 1.05, the floor will generate a different layout upon restarting. The golden gate to Mega Satan will be locked if it was previously opened with Collectible Key Piece 1 iconKey Piece 1 and Collectible Key Piece 2 iconKey Piece 2 or Collectible Dad's Key iconDad's Key. As the Key Pieces are consumed upon entering The Chest or Dark Room, the door can only be opened again for that run by using Dad's Key one more time.
  • The chests present in the I AM ERROR room from Template:Stage and Template:Stage always contain items.
  • Using the Rune of JeraRune 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 you to a Devil Room or Angel Room from an I AM ERROR room, exiting the Devil Room will return you to the room you were in before entering the I AM ERROR room.
  • Entering the I AM ERROR room from Template:Stage / Template:Stage / Template:Stage II will randomly result in a trapdoor or a beam of light. The player may have to end their run early in the Template:Stage / Template:Stage.
  • It is probably not a good idea to go to the I AM ERROR room on Template:Stage / Template:Stage / Template:Stage II, because the player will be unable to pick up Collectible The Polaroid iconThe Polaroid / Collectible The Negative iconThe Negative, and can not go to either Template:Stage or Template:Stage, having to end their run in Template:Stage or Template:Stage.
    • 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 on the 12th Rewards and onwards in the Sacrifice Room have a 50% chance to send you to Template:Stage. This may be useful if an I AM ERROR room locked you out of the Collectible The Negative iconThe Negative.
    • (in Repentance) This rule also applies to players trying to reach Template:Stage / Template:Stage II from Template:Stage / Template:Stage / Template:Stage II. The I AM ERROR room will instead send players to Template:Stage / Template:Stage / Template:Stage I, and players will not be able to pick up (in Repentance)Collectible Knife Piece 1 iconKnife Piece 1.
    • (in Repentance) This rule also applies to players trying to reach Template:Stage / Template:Stage II from Template:Stage / Template:Stage / Template:Stage II. The I AM ERROR room will instead send players to Template:Stage / Template:Stage / Template:Stage I, and players will not be able to pick up (in Repentance)Collectible Knife Piece 2 iconKnife Piece 2.
    • (in Repentance) This rule also applies to players trying to reach Template:Stage / Template:Stage I, or Template:Stage I.
      • However, in Template:Stage / Template:Stage II, if you kill Mom & Mom's Heart first, then enter the I AM ERROR room, the trapdoor inside will lead players to Template:Stage.
    • (in Repentance) This rule also applies to players trying to reach Template:Stage. The I AM ERROR room of Template:Stage / Template:Stage / Template:Stage II will instead send players to Template:Stage / Template:Stage / Template:Stage I, and players will not be able to enter the Strange Door.
  • (except in Rebirth) There is a rare closet room in Template:Stage and Template:Stage containing an I AM ERROR shopkeeper. This is not an I AM ERROR room, and can be exited normally.
  • (except in Rebirth) There is a 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 hard numbers required to access this room, and the name of the room itself, it could be a failsafe.


Bug Bug! PC If you go inside a trapdoor while in (in Repentance)CorpseCorpse, the game will crash upon entering the next floor.
