Avalanches
An avalanche deals major or even massive bludgeoning damage to creatures and objects in its path. These victims are also buried under a significant mass. Creatures caught in an avalanche's path can attempt a Reflex save; if they succeed, they take only half the bludgeoning damage, and if they critically succeed, they also avoid being buried.
Burial
Allies or bystanders can attempt to dig out a buried creature. Each creature digging clears roughly a 5-foot-by-5 foot square every 4 minutes with a successful Athletics check (or every 2 minutes on a critical success). Using shovels or other proper tools halves the time.
