Teleport 2.0

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

Effects

 * When used, teleports Isaac to the next room that has not been explored yet.
 * The room that you are 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 you will be teleported into is predetermined, first available on this list chosen:
 * Grave Room.
 * Normal rooms.
 * Boss Room.
 * Super Secret Room.
 * Shop.
 * Treasure Room.
 * Sacrifice Room
 * Dice Room.
 * Library.
 * Curse Room.
 * Mini-Boss Room.
 * Challenge Room / Boss Challenge Room.
 * Bedroom.
 * Arcade.
 * Vault.
 * Secret Room.
 * Devil Room / Angel Room.
 * I AM ERROR room.
 * With every room above on the level mapped, Teleport 2.0 will keep you in the I AM ERROR room.
 * You cannot teleport to Crawl Spaces, the Boss Rush room, the entrance, Mega Satan,  alternate floor entrances, or the  Ultra Secret Room.

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 unvisited rooms would exist at that point.
 * This item is one of the two reliable ways to reach the I AM ERROR room in-game, the other being the +  interaction — another paradox.
