Chaotic Lightning

You send out a bolt of chaotic black lightning towards a creature that you can see and that hit you with an attack within range. Make a Ranged Spell attack against it. On a hit, it suffers 2d8 points of Lightning damage and the spell bounces to a random creature within 10 feet of the target. Make another Ranged Spell attack. On a hit, that creature suffers 2d8 points of Lightning damage and the spell ends.

For each level of spell slot used to cast this spell beyond 1st, the Lightning bounces an additional time. For every 2 levels of spell slots used to cast this spell beyond 1st, the damage increases by an additional 1d8.
