Teleport 2.0

Teleport 2.0 is an activated item added in 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 applicable.
 * When used in a room with enemies in it, it will teleport Isaac back into the same room.
 * The order of types of rooms you will be teleported into is predetermined, first available on this list chosen:
 * 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, Blue Womb entrance or Mega Satan.

Synergies

 * : Having two charges by the end of the floor can guarantee getting to a Devil/Angel room and I AM ERROR, assuming the secret rooms have been explored.
 * /: Allows you to know the location of Secret/Super Secret rooms.
 * : Leaving the batteries it generates around the floor allows you to save them up and have multiple charges to use at the end of the floor once everything is explored, maximizing the chance of getting to I AM ERROR.
 * : Allows Isaac to visit the Angel Room without the use of Teleport 2.0, allowing reliable passage to I AM ERROR rooms.
 * : Allows Isaac to visit the Angel/Devil Room without the use of Teleport 2.0, allowing reliable passage to I AM ERROR rooms.
 * : Allows Isaac to know the location of all rooms on the floor, including the Secret/Super Secret Room.
 * : Allows you to find the location of Secret/Super Secret rooms.

Trivia

 * Teleporting to the I AM ERROR room when all rooms on the map are explored is a reference to the error the item would otherwise cause.
 * It is as if the item is saying "ERROR, there are no more unexplored rooms left."
 * This item is one of the two reliable ways to reach the I AM ERROR room in game, the other being the Blank Card + ? Card interaction -- another paradoxical situation.
