You cause a massive tsunami of snow and ice to appear out of thin air, pounding your foes and burying them in icy death.

The avalanche appears in a cylinder that is 10 feet tall with a 60 foot radius, centered on a point you can see within range. Each creature in the cylinder must make a Dexterity saving throw. A creature takes 8d8 bludgeoning damage and 8d6 cold damage on a failed save, or half as much damage on a successful one. In addition, a creature which fails its saving throw is buried under snow and ice, is rendered unconscious, and will suffocate in a number of rounds equal to its Constitution bonus.
