Cold Snap

A bright streak flashes from your pointing finger to a point you choose within range and then encases the target in ice. A target must make a Constitution saving throw. A target takes 8d6 cold damage, and becomes restrained in ice on a failed save for 5 rounds or until a successful save is made, or takes half as much damage on a successful save and is not restrained.

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.
