Teleport trap

A teleport trap is a magical trap that instantly teleports any player or monster that walks on it to another location on the level, even if flying. Because they are an instantaneous form of teleportation, they make for good emergency escape routes, especially if you've already explored most of the current floor.

Types

Temporary

File:Temporary teleport trap.png Temporary teleport traps are randomly generated, and are always visible. Once a player or monster has passed over it once, the trap will disappear. This includes if the subject was not actually teleported (e.g. a Formicid with stasis).

Permanent

File:Teleport trap.png Permanent teleport traps are only encountered as part of a pregenerated vault, most notably the Hall of Zot on Zot:5. Like temporary traps, they are always visible, though as their name suggests, do not disappear.

Items on a permanent teleport trap are stuck and cannot be accessed normally, even with autopickup. You must use the Apportation spell or have the -Tele intrinsic (or be a Formicid) in order to retrieve it.

Exploration

When uncovering dungeon tiles, you may randomly encounter sourceless malevolence that manifests itself as a teleport trap. Unlike the physical traps, the exploration effect will always teleport you next to monsters (if possible), similar to teleportitis. It does not have a physical presence.

History

• Traps in general were overhauled in 0.23 - see the Traps#History section for more details.
• Prior to 0.16, there was still a 'disarm trap' command, and traps did care about whether the player is flying.
• Prior to 0.15, all teleport traps were permanent.
