Arcannon

The Arcannon, or Arcane Cannon, looks like a Gatling gun. The body is made out of tough magical wood. The wood has metal bands attached to it fitted with crystals.

This weapon has 6 charges. You can expend up to 3 charges as an action. When you expend 1 charge, the cannon charges up and fires out a large glowing blue projectile. The projectile splits into 1d6 magic missiles magic missile which act using the normal magic missile rules. You can make them target any creature(s) within the spell's range.

When you expend more than one charge, the initial projectile is bigger and brighter, and you roll to create that many d6 magic missiles. 2 charges means 2d6, 3 charges means 3d6.
