Wave of Frost

A blast of cold air erupts from your hands. Each creature in a 30-foot cone must make a Constitution saving throw. On a failed save, a creature takes 6d6 cold damage and is restrained until the end of your next turn. On a successful save, the creature takes half as much damage and is not restrained.

A creature killed by this spell becomes a frozen statue until it thaws.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
