Plunger Chute
Level 3
A section of floor that drops away into a chute, then slams a plunger down behind the victim to drive them deeper. There's no scrambling back out the way you fell.
To disable it, a creature can attempt DC 23 Thievery (expert) to jam the trapdoor shut or activate a hidden bypass switch by twisting a fitting on the gas lamp.
