Akhomem's Snowball

A blue cold streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an explosion of Ice shards. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 Ice damage on a failed save, or half as much damage on a successful one. Hit or miss, the shard then explodes. The target and each creature within 5 feet of the point where the ice exploded must succeed on a Dexterity saving throw or take 2d6 cold damage.

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.
