Upon triggering, the floor in the affected area collapses into a chasm, except for a very narrow balance beam in the center.

  1. If a creature on the pressure plate jumps down, taking fal...

A player falls into a pit that is a chute into an automated mummy-wrapping machine.

A murky pool with a beautiful, especially rare water flower floating on its surface. If players approach, an ancient and powerfully hungry octopus launches itself onto the player's face (Reflex save DC 15 negates).

Upon triggering, all exits seal up, holes in the wall open, and water rushes in, quickly flooding the area. The water only comes up to about mid-chest height on a human, then freezes solid in an instant. Characters are trapped, and possibly freezing to death.

A huge tapestry of an ancient battlefield hangs on the wall. It appears to depict an army that is facing the viewer. Archers, spear men, battlefield wizards, and even siege weapons are in evidence.

Passing in front of the tapestry activates the trap, and the characters become targets of the sol...

As the characters proceed, the other end of the corridor or room never seems to get any closer. Try as they might, it always extends further away to the exact same degree that the characters proceed.
