Arcane Bolt

Seeking a response to the Warlock's Eldritch Blast with the Agonizing Blast invocation, Wizards have used the local weave to alter the Magic Missile spell and create a similar effect. Less accurate, but more powerful, than the original spell.
You hurl a bolt of humming energy. Make a ranged spell attack against one creature or object in range. On a hit, the target takes 1d8 + casting modifier in Force damage.

Cantrip Upgrade. The spell creates two bolts at level 5, three bolts at level 11, and four bolts at level 17. You can direct the bolts at the same target or at different ones. Make a separate attack roll for each bolts.
