Billowing Steam
A creature enters the area of the trap
All four vents rapidly heat and let out steam for 5 seconds, filling room with a painfully acrid smell. Each creature in the room must attempt a DC 29 Fortitude save, and the trap then rolls initiative.
Critical Success The creature is unaffected.
Success The creature is Sickened 1.
Failure The creature is Sickened 2 and Blinded.
Critical Failure The creature is Sickened 3, and, struck by a coughing fit, falls Prone.
(4 actions) Each of the four steam vents uses a single action each to emit superheated steam, which spreads for 60 feet along the wall from its location and extends out from the wall by 30 feet, dealing 2d12+13 damage to each creature in their range (DC 29 Fortitude save). For each disabled vent, the trap loses 1 action each turn.
The steam vents cease to operate 1 minute after all creatures have left the area and go into a maintenance cycle for 1 hour. After this time, they can be triggered again.
