Enchanted Bolt

The user taps into every ounce of their magical potential, to launch a multicolored bolt at their foes. You may choose any damage type except Bludgeoning, Slashing or Piercing for the spell to inflict. The target takes 2d10 damage, and the caster can burn additional spell slots to add a D10. There is no limit to how many slots can be burned per casting, and higher level slots do not yield more damage then lower-level ones. The base form of the spell only targets one target, and each additional slot burned allows you to target an additional creature. Each slot also gives the spell an additional 10 feet of range.
