Gun Mancer

Gun Mancers are people who combine their innate magic with advanced weaponry. Most Gun Mancers come from areas where magic is not commonly practiced, and their civilization instead relies on the power of technological innovation. Gun Mancers found a way to enhance their complex weapon with magic in order to more effectively take out their enemies.

Magic and Bullets

Starting at 1st level you gain the ability to attune to a gun making it your casting focus. When you attack with that weapon you can use your Charisma modifier, instead of Dexterity, for the attack and damage rolls. Additionally, you may spend 2 sorcery points to enhance your reflexes and quickly draw your weapon in order to make an attack with it as a bonus action. 

Extra Attack

Starting at 6th level, you can attack twice, instead of once, whenever you take the Attack action on your turn. Additionally, you may spend 3 sorcery points to cast a spell in place of one of those attacks.

Chambers of Spell Storing

At 14th level you gain the ability to imbue your gun with spells. You may store each chamber of your gun with a spell that triggers when you fire your gun. The spell casts wherever the bullet loaded into the spell chamber lands. You may load a spell into each chamber of your gun. You must expend a spell slot equal to the level of the spell you are loading your gun with in order to use this ability. 

Fan the Hammer

At 18th level your capacity to use magic to enhance your reflexes has greatly improved. as an action you may use 5 sorcery points to fan the hammer and fire 6 bullets at once.
