An arc of lightning jolts towards a creature within 30 feet of you. Make a ranged spell attack against the target. On a hit, the target takes 1d6 lightning damage and you may immediately make another ranged spell attack against a different creature within 15 feet of the first. On a hit that creature also takes 1d6 lightning damage.
This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
