Cryo Blast

The moisture in the air coalesces and condenses into a marble sized ball of cracked ice before exploding into a shower of razor sharp ice shards and freezing wind. Each creature in a 10-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 5d6 cold damage and 5d6 bludgeoning damage on a failed save, or half as much damage on a successful one.

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