Mud Pot

COMPLEX HAZARD 1

Stealth +8 (trained)

Description Solid ground gives way to a lake of bubbling mud that burns anyone who enters and routinely belches out sulfur.

Disable DC 17 Survival (trained) to find and remove the stones blocking the flow of water to the mud pot. The water decreases the viscosity of the mud, allowing steam and sulfur to escape gradually, rather than in violent bursts, so creatures can pass through unharmed. The hazard requires two successful checks to disable. Attempting the check takes two actions.
