Avalanches

Though the term avalanche specifically refers to a cascading flow of ice and snow down a mountain's slope, the same rules work for landslides, mudslides, and other similar disasters. Avalanches of wet snow usually travel up to 200 feet per round, though powdery snow can travel up to 10 times faster. Rockslides and mudslides are slower, sometimes even slow enough that a character might be able to outrun them. 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.
