Crackling Shot

A jolt of crackling energy streaks toward a creature you can see within range. Make a ranged spell attack against the target. On a hit, the target takes 1d12 lightning damage. The caster also takes 1d4 lightning damage. 

The spell creates more than one jolt when you reach higher levels: two jolts at 5th level, three jolts at 11th level, and four jolts at 17th level. You can direct the jolts at the same target or at different ones. Make a separate attack roll for each jolt. The caster suffers an additional 1d4 lightning damage for each jolt created.
