Electric Blast

A blast of lightning forming a radius of 5 feet around a point it lands on shoots out from you. Each creature in within the range must make a Dexterity saving throw. A creature takes 1d8 lightning damage on a failed save, or a quarter as much damage on a successful one.
The lightning ignites flammable objects in the area that aren't being worn or carried.

At Higher Levels. The damage and range increase as you gain levels, 1 foot is added to the radius per level and the damage increases by 1d8 every 5 character levels
