Teleporter

Verified against the spelunky.ai port v0.1.10 on 27 October 2026.

Held, it moves the player a random 4 to 8 blocks the way he faces, or up with the up key, through anything in between. Where that's inside rock, it looks a few blocks higher, and if it finds no room there, the player is crushed. A monster where he lands is destroyed outright. It has no wait between uses. Rare Shops and the Dice House sell it, and Crates and buried blocks give it away.

The Teleporter is picked up like any item, crouching over it and pressing the attack key. While it's held, the attack key uses it, on the ground or in the air; crouching, the key puts it down in front of the player instead ^[3]. It isn't thrown. Each use:

1. Picks the spot: 64–128 pixels (16 pixels times a whole number from 4 to 8) the way the player faces, or that far above him with up held, no closer to the room's sides than 8 pixels and no higher than its top row ^[4].
2. Looks for room: while the spot is inside a block, it moves up a block, at most three times ^[5].
3. Moves him there, with three sparks where he was, and Kali's ball and chain with him if he has them; he's left falling ^{[6] [7]}.
4. Destroys a monster that's where he lands: it loses 99 hit points, bleeds, and is gone ^[8].

In the clip, the player uses it facing a Snake five blocks away; he reappears where it was, and the Snake bursts into blood and is gone. The game's tally of Snakes killed doesn't change ^[9].

With down held and the player not crouching, the key does nothing ^[10]. The Teleporter sets no wait of its own between uses, but a sideways use only picks a new spot once the wait another weapon's shot starts has run out; inside it, the player is moved to the spot its last use picked ^[11], or to where he last stood holding a ware he hadn't paid for, a readied bomb arrow or pressing the pay key, as the game's check for a shop writes the same spot ^{[12] [13]}. If none of these has set it on the level, the game stops with an error ^{[14] [15]}.

The Teleporter goes with the player through a level's exit if he's holding it, and is in his hands on the next level ^{[16] [17]}. He drops it when he's stunned, or when he teeters too long at a ledge's edge ^{[18] [19]}.

The spot is picked only by distance, and it looks for room by moving up three blocks at most, so the player can land inside rock. In the second clip, used facing left in a shop, it puts him five blocks away, inside the rock three blocks up from where it first tried, and he dies on the spot with all four hearts ^{[21] [22]}.

A Rare Shop stocks one only if the level hasn't got one already ^[27], and it adds 10% of the base price for each level past the second ^[28]. Shops are made from level 2 on ^[29], and level 16, Olmec's Lair, has none:

The Dice House puts its prize up from the same set of rare items, and a roll of seven gives it away ^{[30] [31]}. Every block of rock away from the level's edges that isn't gold and holds no gem has a 1 in 1200 chance of hiding an item, one of nineteen at random ^{[32] [26]}. In custom levels, it's the level editor's tile ? ^[33].

Paying for one, or carrying one out of a shop without paying, which angers the Shopkeeper, shows "YOU GOT A TELEPORTER!", and it stays in the player's hands ^{[34] [15]}.

• Sealed places. It goes through walls, so it can put the player inside places nothing else opens, the Moai's chamber among them ^[15].
• The ball and chain. Kali's ball and chain come with the player wherever it takes him ^[35].

• It looks no more than three blocks up for room, so beside thick rock it's safer used along an open passage, where the spot it picks is likely to be open.
• It destroys a monster outright, a Megamouth's 40 hit points or a Yeti King's 30 alike.

• Before it moves the player, it puts him no higher than 8 pixels from the room's top, a line that changes nothing, as the next ones move him anyway ^{[36] [15]}.
• A commented-out // state = STANDING; sits a few lines above the one that leaves him falling ^[37].
