Charged Step

Briefly surrounded by blue static, you teleport up to 30 feet to an unoccupied space that you can see. One chosen creature that is within a straight line from your original position to the point at which you teleported to must make a Dexterity saving throw, taking 3d6 lightning damage on a failed save, or half as much on a successful one. 

At Higher Levels. When you cast this spell using a spell slot of 5th or higher, the damage increases by 1d6 for every two slot levels above 3rd.
