Black Tentacles Trap
A tapestry depicts a ship being pulled beneath the waves by the tentacles of some huge, aquatic beast.
The tapestry conceals a door. Touching the door’s handle triggers a Failure.
Exploration. A Perception or Investigation check, or moving the tapestry, reveals a locked door of black iron behind the tapestry. (At the Narrator’s discretion, the door may lead either to another area or an alcove containing a Minor Treasure.)
Once the door is discovered, an Arcana, Investigation, or Perception check, or examining the door, reveals a small magical glyph of warding on the door’s handle.
Characters that make a Stealth check to hide may eventually see denizens of the dungeon pass through the door, speaking a password that disables the trap for 1 minute.
Keeping Clear. Opening the door without touching the handle, such as with mage hand or a similar effect, doesn’t trigger the trap.
Spell Effect. This is an evocation effect created by a 4th-level spell. Casting dispel magic on the tapestry triggers a Critical Success.
- A creature can make an Arcana or thieves’ tools check to weaken the glyph.
Potential Outcomes
Critical Failure or Failure. The glyph casts black tentacles on a 20-foot square next to the door. The trap is then disabled.
Success. The trap is temporarily weakened. For 1 round, each Success counts as a Critical Success.
Critical Success. The trap is disabled.
