A flurry of magic snowballs erupts from a space you can see within range, filling a 15-foot cube. Each creature of your choice within that area must make a Dexterity saving throw. A creature takes 3d6 cold 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 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
