This hand cannon has no discernable way of reloading ammunition. It instead syphon's the attuned wielder's arcane energies and converts it to stored magical ammunition. The hand cannon is capable of firing a multitude of different magical projectiles.
While the hand cannon is attuned it becomes the artificer's arcane firearm as seen in the Artillerist subclass for as long as it remains attuned to the artificer.
The artificer can expend a charge to fire the hand cannon. The artificer can add their proficiency bonus and INT modifier to their attack rolls. Each projectile does a base 3d8 damage + proficiency bonus + INT modifier.
The hand cannon uses the artificer's Intelligence modifier to resolve attack and damage rolls, rather than their Dexterity modifier for ranged attacks.
This hand cannon has 8 charges that replenish on a short or long rest. Additionally, the artificer can spend one spell slot of 1st level or higher as a bonus action to replenish all expended charges as the hand cannon syphons more arcane energy to fuel it's shots.
Upon attunement the artificer can choose a damage type from the allowed list. The hand cannon's damage type can be changed at the conclusion of a short or long rest. Additionally, the artificer can spend one spell slot of 1st level or higher as a bonus action to change the damage type.
