Here is new version

Fireball Musket
The Fireball Musket is based off of the traditional fireball spell, and is a large, heavy musket with a cover over the muzzle and with a well for the magitek cell to lock in place under the chamber. By drawing the hammer back halfway the muzzle cover is lifted and the musket begins to produce light as a bullseye lantern. By drawing the hammer all the way back and willing it the musket begins to charge. 1 round of charging costs 1 use and produces a 3d fireball and the musket begins to glow dimly, 2 rounds consumes 2 uses and its glow is quite obvious, 3 rounds and the glow is bright and angry. Fired using guns (rifle) or other appropriate skill.

As long as it is loaded and a charge remains it can be used as a lightsource.
