Electric Flash

Streaks of lightning begins to form in your hand, aswell as a small charge on spells location. The lightning charge on then blossoms into a flash of exploding light. Each creature in a 15-foot-radius sphere centered on that point must make a Dexterity saving throw or take full damage and are blinded for their next action. A target takes 6d6 lightning damage on a failed save, or half as much damage on a successful save and vision remains unchanged.

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.
