Animated Firearm

You reach out and touch a firearm creating a floating,  animated weapon that lasts for the duration or until you cast this spell again. When you cast the spell, you can make a spell attack against a creature within the range of the weapon. On a hit, the target takes force damage equal to the damage dice of the weapon + your spellcasting ability modifier. As a bonus action on your turn,  You can repeat the attack against a creature within the range of the weapon. The weapon follows you, floating above your shoulder.

For each level above 2nd level, You add +1 to your damage with the chosen firearm as well as add an additional damage die to the weapon.
