Targeted retribution

You summon a storm of pure spite down from the heaven to attack a target of your choice who gets stuck with a bolt of energy. The bolt may be lightning, fire, or thunder damage. The target must make a dexterity saving throw or take 2d6 damage per level of the spell cast or half as much on a save. Any caster may use their action to cause a bolt to attack that same person using their spell save dc. 

The damage increases 2d6 for each level of the spell cast
