Electrical Smite

A column of crackling lightning thunders from the heavens. Each creature in a 40-foot-high, 10-foot-radius cylinder centered on the point of origin must make Dexterity saving throw. A creature takes 4d6 lightning damage and 4d6 thunder damage on a failed save, or half of that damage on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, your choice of the lightning or thunder damage increases by 1d6 for each slot level above 5th.
