You call down a single bolt of lightning, blasting all creatures in a tight circle. Choose a point in range, each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. Creatures take 3d6 lightning damage and 3d6 thunder damage on a failed save, or half as much damage on a successful one.

All creatures within the sphere must also make a successful Constitution saving throw or be deafened and blinded until the end of their next turn.

At Higher levels: When you cast this spell using a spell slot of 4th level or higher, the lightning and thunder damage both increases by 1d6 for each slot level above 4th.
