Blizzard

A swirl of hail crashes down around you and then blossoms with a low rumble into a storm of snow and ice. Each creature other than you in a 20-foot-radius, 60-foot-high cylinder centered on you must make a Dexterity saving throw. A target takes 8d6 cold damage on a failed save, or half as much damage on a successful one. A flying creature that fails its saving throw crashes into the ground and falls prone.

The blizzard spreads around corners. It freezes water in the area that isn't being worn or carried.

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.
