Sword Storm

You conjure forth a volley of magical swords to rain down on a point within range. Each creature in a 10-foot radius sphere centered on that point make a Dexterity saving throw. A target takes 8d8 slashing 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 1d8 for each slot level above 3rd.
