darkness blast

A beam of hissing  darkness streaks toward a creature within 130. Make a ranged spell attack against the target. On a hit, the target takes 2d10 force damage but you take 10 hit points.

The spell creates more than one beam when you reach higher levels: two beams at 7th level, three beams at 11th level, and four beams at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.
