Ethereal Strike

A bolt of crackling energy streaks toward a creature within range. Make a melee spell attack against the target. On a hit, the target takes 1d10+2 force damage.

The spell manifests more strikes when you reach higher levels: four bolts at 5th level, six bolts at 11th level, ten bolts at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.
