A Geyser trap in action.

The Geyser is a trap that spews a vertical stream of fire which deals a base damage of 40 / 80 / 120 and a knockback of 2 (Very weak)[1]. It will activate when a player touches it or when it is triggered via wire. Geysers are found naturally-placed in random areas that are deep enough to generate lava, including the Underworld and deeper Cavern areas. They are generated without Pressure Plates or wires attached to them.

Geysers can be placed on the top or bottom of blocks, facing upward or downward respectively, but not sideways.

Geysers consume no ammunition, and their output is limited only by a cooldown period of 3.33 seconds[1]. Geyser fire streams extend up to 20 tiles up or down (which can be blocked by solid blocks) and last for 1 second. The stream also has the ability to move through solid blocks and liquids before creating the fire stream (see Notes for details).[2]

Notes

  • The Geyser projectile requires a 3-tile-high space unoccupied by solid blocks or liquids to create the 20-tile-high fire stream. If any of the two columns of tiles in the direction of Geyser stream is spewing out (e.g. the tiles above the Geyser if it is facing upward) is blocked by solid blocks and/or liquids, the Geyser stream will be able to move through them (indicated by puffs of smoke) and spew out the fire stream at the first 3-tile-high opening. Counting from the tile just above (or below) the Geyser, the stream can move through obstacle with a maximum distance of 28 tiles. Adding a solid block or a full tile of liquid to the 29th tile will prevent the fire stream from forming.
    • The Geyser projectile is still capable of dealing damage when moving through obstacles. If the obstacle is 29 tiles high, it can damage the entities directly above (or below) the tile.
    • If the Geyser is facing upward, hammering the 29th solid block into half-block allows the fire stream to spew out.
  • Geysers are highlighted by the Dangersense buff.
  • Activated Geysers will not free any placed objects, including Torches.
