Yamu's Arcane Missile

You shape the weave into a bolt of arcane energy and fire it at a creature within range.

Make a spell attack, on a hit, the target takes 2d6 force damage plus and additional amount of force damage equal to the number of character levels you have in classes that naturally gain access to spell slots (e.g. Wizard, Ranger, Warlock; subclasses like the Eldricth Knight or Arcane Trickster do not work for the purposes of this spell).
