Warp lightning

choose within range, bolts that slam into anyone beneath the green lightning storm, crackling bolts of energy that rip through armor and flesh alike. All creatures in a 15-foot radius centered on the point must make a Dexterity saving throw. On a failure, the target takes 2d6 lightning damage and 1d6 force damage, on a success they take only half this damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you deal 1d6 more force damage per spell slot level above 2nd.
