Bolt of Blasting

A spectral crossbow appears at your wrist, it fires a bolt at a target within range (the bolts are considered magical when fired). Make a ranged spell attack against the target. On a hit the target takes 2d4 piercing damage damage.

The crossbow fires more bolts when you reach higher levels: two bolts at 5th level, three bolts at 11th level and four bolts at 17th level. you can direct the bolts at the same target or at different ones. Make separate rolls for each bolt.
