Spellslinger

Prerequisites: The ability to cast spells and proficient with firearms.

You have combined your knowledge of magic and firearms, allowing you to cast spells while wielding a gun. When you cast a spell that requires an attack roll, you can choose to use your firearm as the means of delivering the spell. If you do so, the bullet you fire becomes infused with the magic spell.

Note: The exact mechanics of this feat will depend on the spells you can cast and the firearms you use. Work with your DM to determine how this feat will work in your game.
