Carfine's Static Boom

Between your hands, a static charge builds in power and condenses in size until it's a ball and can’t hold anymore. The caster directs the ball with a push of the palm to a distance of 120 ft and releases the concentration to detonate for 8D6 lightning damage in a very bright and very loud 20 ft sphere.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
