I AM ERROR

The I AM ERROR room is a rare room that isn't connected to any other room on the floor; it can only be found via teleportation. 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.

Arriving at the I AM ERROR room

• The only items that can bring you to the I AM ERROR room are Undefined, Telepills, Teleport 2.0, and Blank Card with ? Card
• The Undefined item has a fixed list of destinations (I AM ERROR room being one of the few possibilities), being a quite reliable way to reach the I AM ERROR room.
• Telepills have a very small chance of teleporting you to the I AM ERROR room.
• The I AM ERROR room can be reached by using Teleport 2.0 when all rooms on the floor have been explored, including secret rooms and the Devil/Angel room.
• The I AM ERROR room can be reached by using Blank Card with ? Card. This consumes both the Blank Card and the ? Card.
• The I AM ERROR room cannot be reached anymore in The Chest, Dark Room and the final floor of the Daily Challenge.

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.
  • However if you manage to spawn a Crawl Space in the I AM ERROR room, the character will return to the room it 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 Sheol or Cathedral.
• Using the trapdoor in The Chest or the Dark Room will restart the level, similar to the effect of the Forget 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 Key Piece 1 and Key Piece 2 or Dad'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 Void can also be repeated with this method.
• The chests present in the I AM ERROR room from The Chest and Dark Room always contain collectible items.
• Using the Rune of Jera in most of these room configurations can allow Isaac to summon and pick up a ridiculously large amount of items, making the item especially effective in this room.
• If a Red Chest teleports you to a Devil 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 Womb/Utero/Scarred Womb 2 will randomly result in a trapdoor or a beam of light. Unless both The Polaroid and The Negative have been obtained, the player may have to end their run early in the Sheol/Cathedral.
• It is probably not a good idea to go to the I AM ERROR room on Depths/Necropolis 2, because the player will be unable to pick up The Polaroid/The Negative, and can not go to The Chest or the Dark Room, having to end their run in Sheol or the Cathedral.
  • Reaching another I AM ERROR room in the above-mentioned levels would allow continuing the run beyond them, even lacking the prequisite items.
• There is a rare closet room in The Depths and Necropolis containing an I AM ERROR shopkeeper. This is not an I AM ERROR room.

Trivia

• The I AM ERROR room is a reference to the NES game "The Legend of Zelda 2: 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.
