Shaft, Trampoline and Spiked Platform


There is a tiny closet at the end of the hallway.

Mechanical Trap

 

The closet has what appears to be a secret door in the back. However, this just triggers the floor, which is a trap door, to open up.

A DC 10 Wisdom (Perception) check detects a secret door in the back of the closet.

A DC 12 Intelligence (Investigation) check reveals that the door appears to be up against a wall, and that there is also a small seam that runs the perimeter of the floor.

When a target attempts to open the secret door, the floor swings away. Falling can be avoided with a successful DC 12 Dexterity saving throw.

When the target falls, they fall 60 feet down a shaft onto a trampoline. When they strike the trampoline, a panel slides over the shaft 10 feet above the trampoline. This panel is covered in spikes.

The target bounces on the trampoline and strikes the panel, taking 5d6 bludgeoning and 4d6 piercing damage, before falling back to the trampoline.

Once on the trampoline, a DC 12 Wisdom (Perception) detects a small switch that retracts the panel. This switch can be jammed with a successful DC 14 Dexterity check with thieves’ tools to prevent the panel from sliding back out.
