Subsidence

Routine A subsidence has no duration. Those who aren't prepared when it occurs attempt a DC 22 Reflex save.

Critical Success The character avoids the unexpected subsidence entirely.

Success The character takes 4d6 bludgeoning damage from the subsidence.

Failure The character takes 8d6 bludgeoning damage from the subsidence. If the subsidence is a sinkhole, the character ends up at the bottom of a hole 1d6 × 5 feet down and can clamber out with a successful DC 22 Athletics check. If the subsidence is a mudslide, rockslide, or avalanche, the character is knocked prone and swept 200 feet away.

Critical Failure The character takes 16d6 bludgeoning damage from the subsidence and is buried. Buried PCs are at risk of suffocation; see Burial for details on how a buried creature can be rescued.
