A barrage of magic static balls erupts from a point you choose within range. Each player or creature within a 10-foot-radius sphere in the center must make a Dexterity saving throw. A creature takes 3d6 lightning 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.
