Recall Knowledge DC 28 (arcana)

Disable DC 33 thievery (master) to disable the hidden mechanism on the north wall, immediately sucking the gas from the room, or DC 29 thievery (expert) to adequately plug one of the seven nozzles. When all seven nozzles are plugged or destroyed, the trap is deactivated.

Seven nozzles hidden within holes in the 15‑foot-high ceiling release a poison gas.
