Befuddling Gas Trap

Seven hidden nozzles ready to flood the room with a mind-fogging vapor. The gas creeps in unnoticed, thickening with each passing moment until those who breathe it can no longer trust their own senses.

Effect Gas fills the chamber. Creatures within the chamber must succeed on a DC 30 Fortitude save or become stupefied 1 (stupefied 2 on a critical failure). The trap then rolls initiative.

Reset After an hour, the trap deactivates; the gas disperses slowly, and the doors can be opened again. After 24 hours, the gas builds up and the trap can be triggered again.
