Anak's Lightning Storm

You teleport up to 30 feet in a straight line to an unoccupied space that you can see. Each creature in the line must make a Dexterity saving throw. A creature takes 5d6 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 4th level or higher, the damage increases by 1d6 and the range increases by 10 ft. for each slot level above 3rd.
