Arcane Flintlock

An ancient looking device that is powered by arcane energy and clockwork gears of gnomish design.

The “Magazine” of this device is a crystal about the size of a gold piece in circumference and an index finger in length attached in the butt of the device. The Crystal it’s self holds for charges of arcane energy but a better crystal could possibly allow it to hold more charges. The crystal some cells can only hold four types of arcane energy fire, ice, lightning and acid. The crystal will then correspondingly glow with the color of the energy it holds within (red, blue, yellow, green)  And once the energy is consumed will become dimmer until it no longer glows. These crystals can be recharged by careful casting of a spell of the corresponding energy into said Crystal With a successful attack roll of ac12 for a base of a 4 charge Crystal (add 2 to the ac per additional charge crystal with a max of 8 charges). A cantrip refills one charge, a first level spell refills two charges and etc. but if a spell does not have an attack role in it it cannot be loaded into the Crystal (aka fireball and the like). If however, the attack does not make it over said AC then the charge fails and on a natural one the Crystal shatters. 

when firing Make a ranged spell attack. On a successful attack deal 3D6+4 of the type of arcane energy damage. If however the user rolls under a five the guns clockwork components jam and will need to be repaired. If the user roles and natural one the gun misfires and the crystal shatters dealing a recoil damage of 2 D6 blast to the user while also jamming the gun.

Proficiency with a Pistol allows you to add your proficiency bonus to the attack roll for any attack you make with it.
