**Teleport 2.0** is an activated item added in *The Binding of Isaac: Afterbirth*.

## Effects

* Teleports Isaac to a room that has not been explored yet. Normal rooms are prioritized over special rooms, and common special rooms take priority over rarer ones.

## Notes

* The room that Isaac is teleported into will be touching an explored room, if possible.
* When used in a room with enemies in it, Isaac is teleported back into the same room, resetting it.
* The order of types of rooms is predetermined, first available on this list chosen:
	1. Grave Room /  Mirror Room /  Mine Cart Room
	2. Normal rooms
	3. Red Rooms (opened but unexplored)
	4. Boss Room
	5. Super Secret Room
	6. Shop
	7. Treasure Room
	8. Planetarium
	9. Sacrifice Room / Dice Room
	10. Library
	11. Curse Room
	12. Mini-Boss Room
	13. Challenge Room / Boss Challenge Room
	14. Arcade / Vault
	15. Clean Bedroom / Dirty Bedroom
	16. Secret Room
	17. Ultra Secret Room (Mirrored World only, even if it wasn't located)
	18. Devil Room / Angel Room
	19. I AM ERROR room.
* In Cathedral or Sheol, using the I AM ERROR room exit will bring Isaac to The Chest or Dark Room respectively.
	+ This works even if Isaac has the wrong corresponding item ( / ) for that floor.
* In Chest, Dark Room, The Void, and Corpse II, Teleport 2.0 will teleport Isaac to the Devil/Angel room instead of the I AM ERROR room. The same is true when using it on the final floor of a Daily Challenges.
* In The Void, using Teleport 2.0 in the I AM ERROR room will teleport Isaac to The Void again, allowing the floor to be restarted. The floor regenerates with new rooms and enemies. This can be done multiple times.
* A floor's Boss must be defeated in order to access rooms prioritized after the Boss Room with this item.
	+ The exception to this is Corpse II, where simply entering the boss room will count the room as cleared. The hole to the Mother fight does not need to be entered. This allows the player to use this item to access rooms prioritized after the Boss Room without needing to fight Mother.
* Using Teleport 2.0 to try and visit the I AM ERROR room in the Mausoleum/Gehenna II floor leading to the Ascent will instead teleport Isaac to the Angel/Devil room again.
* Using Teleport 2.0 in the Ascent sequence will teleport Isaac to the Angel/Devil Room if all other rooms have been explored. After returning from the Angel/Devil Room, using the Teleport 2.0 again will teleport Isaac to the I AM ERROR room. If it's instead used without exploring any rooms, Isaac will be teleported to the 'starting' room of the floor containing the beam of light up to the next floor.
	+ This strategy also works in Home, taking Isaac to an Angel/Devil Room if all rooms have been explored. Isaac cannot use this to reach the hidden closet room containing Tainted characters, however. Using it after visiting the Angel/Devil Room will not teleport Isaac to the I AM ERROR room, and will instead merely teleport to the same Angel/Devil Room again.
* Using Teleport 2.0 during the The Beast fight will teleport Isaac to a random spot on the screen without interrupting the fight.
* In the Mirrored World, Isaac will teleport to the Ultra Secret Room before the I AM ERROR room. Although it's empty like any other special room inside the Mirror, this can be useful to find the room in the normal world with .
	+ If used again in the Mirrored World, Isaac will teleport to the **Red Room** which leads Isaac back to the main floor; if used once again, Isaac will teleport to the I AM ERROR room of the normal, non-mirrored floor.
* After killing Mom's Heart in Mausoleum / Gehenna II, Teleport 2.0 will teleport Isaac to the I AM ERROR room with hole leading to Corpse, even if there are unexplored rooms on the floor.
* When using it in Womb II to reach the I AM ERROR room, only the trapdoor to Sheol will appear.

## Interactions

* : Spawns flashing blue wisps on the middle ring. Tears have 20% chance of teleporting non-boss enemies to a random location in the current room on hit. Wisps also temporarily vanish every 5 seconds, preventing them from blocking shots or taking/dealing damage.
	+ This effect is identical to 's effect with Book of Virtues, albeit with a 10% higher chance of teleporting enemies on hit.

## Trivia

* Teleporting to the I AM ERROR room when all rooms on the map are explored is a possible failsafe for the error the item would otherwise cause, as no other valid unexplored rooms would exist at that point.
* This item is the successor to .
* This item is one of four reliable ways to reach the I AM ERROR room in-game, the others being the  +  interaction, using  to go beyond the 13x13 level grid, and .
