Subduing Gas Chamber

A sealed room rigged to seal its door and flood with sleeping gas, meant to take captives rather than corpses. Spot the rig with Stealth +10 (Expert); shut it down with DC 26 Thievery (Trained) to disconnect the wire to the counterweight, preventing it from falling, or DC 20 Crafting (Alchemical Crafting) to create a counteragent to the sleeping gas.

Slam Door [Reaction]

Routine (1 action) Each round on its initiative count, the trap pumps more sleeping gas into the room. Any breathing creature in the room is exposed to the toxin.
