Cazita's Shocking Orbs

You create 6 tiny orbs of lightning energy orbiting around you for the spells duration. When you cast this spell and as a bonus action on each of your turns thereafter you can send one orb at a creature you can see within 120 feet. Make a spell attack roll against the targets armor class. On a hit the creature takes 2d6 lightning damage and must make a Constitution saving throw or be stunned until the end of its next turn. On a successful save the creature avoids the stunned condition and takes half as much lightning damage. 

At higher levels: When you cast this spell using a spell slot of 5th level or higher the number of orbs created increase by 1 per higher spell slot up to a maximum of 9 total orbs.
