You rain a storm of lightning bolts that electrify an 40ft radius, 80 foot high cylinder. All creatures in the affected area must make a Dexterity saving throw, taking 6d6 lightning damage and 6d6 force damage on a failure, or half as much damage on a success. The surfaces in the affected area become electrified for one minute. When a creature begins their turn in the area they take 3d6 lightning damage.

At Higher Levels When you cast this spell using a spell slot of 8th level or higher, the force damage increases by 3d6 for each slot level above 7th.
