Avalanche

You conjure a snowy torrent to knock away and freeze your foes. Each creature in a 30-foot cone must make a Strength saving throw. A creature takes 6d6 cold and 4d6 bludgeoning damage and are pushed 30 feet away from you on a failed save. On a success, a creature takes half damage and is not pushed. Additionally the ground within the cone becomes difficult terrain covered in snow for the next minute.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, both damage sources increase by 1d6 for each slot level above 6th.
