False Door Trap
Behind a cracked floor is a 10-foot-square stone door with handles on both the right and left sides.
Turning one of the door’s handles alone does nothing. Turning both handles at the same time triggers a Failure.
Exploration. An Engineering or Investigation check, or an examination of the door, reveals that the door’s hinges are set into the floor horizontally instead of vertically along the sides. A Perception check or an examination of the floor reveals that there are two cracks in the floor, each about 3 feet in front of a door handle. (The door handles are 3 feet above floor level.)
- A creature that braces the door or holds it up while the handles are turned can make a Strength check to prevent it from crashing down.
Potential Outcomes
Critical Failure or Failure. The door bangs down like a drawbridge. Each creature in the 10-foot-square area directly in front of the door makes a Dexterity saving throw . On a failure, the creature takes 16 (3d10) bludgeoning damage from the falling door. On a success, the creature can move out of the way. A solid wall is revealed behind the false door, possibly with a clue written on the wall.
Success or Critical Success. As a Failure, but the door opens harmlessly.
