You release an arc of lighting at a creature within range. Make a ranged spell attack roll against the target. On hit, the target takes 4d12 lightning damage, and you can cause the spell to jump to another target within 20 feet of the first target making a new attack roll for each target. The spell cannot hit the same target twice, or jump to a target out of the spells range. The spell can jump a maximum of five times. On a miss, the target takes half as much damage and the spell does not jump to a new target.
