Aimed Static

A cascade of lightning erupts from your hands or focus in a 30 feet cone. Each creature in the cone must make a Dexterity saving throw. A creature takes 2d12 lightning damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d12 for each slot level above 2nd.
