Voltaic Trident

Three lines of crackling electricity 30 feet long and 5 feet wide emanate from you in directions you choose. One line cannot overlap another, and each creature can only take damage from this spell once per cast. Each creature in a line must make a Dexterity saving throw. A creature takes 2d8 Lightning damage on a failed save, or half as much damage on a successful one.

At Higher Levels: The spell's damage increases by 2d8 for each slot level above 3rd.
