Finally on the subject of firearms and or firearms like weapons I've always have this idea of a non-blackpowder ignited rifle called the Magelock, which essentially is a easy to use firearm that allows spell like projectiles to be shot out of them. Whats completely sets aside the Magelock from your standard fantasy flintlock is its firing mechanism and ammunition.
Function: Ok so a magelocke has a presscussion cap firing mechanism, however can only load one "bullet" through a bolt mechanism. The percussion cap will be located on the right of the weapon(same has any musket) while the bolt handle will be on the left side of the gun. When the bolt is pulled back its opens up a hatch on top of the rifle. The hatch is where the gunner drops the bullet. The bolt then pushed back up and locked in place(locking is done by pushing the bolt handle down) Now this is where things get a bit magical. The ammunition of the rifle isn't an actual bullet, but a transparent cylinder vial about the size of your modern day rifle bullet. Both ends of the vial are covered by two very resistant metal stoppers that have small holes in the middle of them. The metal stopper facing the bolt has a gum like solid that can stop liquids/gases but not solids. The metal stopper facing the barrel of the rifle only has a fitted cork in the middle that can be easily removed by applying force from behind. You see inside the bolt there is also a thin rod that pokes a hole through the vials center mush. At that point the percussion cap can be cocked. Finally the rifle itself is ready to fire. When the trigger is pulled, the percussion hammer goes down and causes a spark. The spark is then conducted through the small thin rod and ignites the liquid in the vial letting out a energy like projectile through the barrel. The projectile that comes out of this Maglocke is completely dependent on the vial's contents and the shape of the barrel as well as the user's imagination. For example, a fire bolt vial ignited in a magelocke with a groved bore barrel will allow the magic bolt to become a faster and more accurate projectile. The substances in the vial are meant to be easy to make, however that's up to debate depending on how magic,alchemy, and materials within the old old world pan out. Also the vials aren't destroyed after the weapon has fired. In fact their made to withstand ignition, however it's very impractical to refill the vials during active combat. Essentially with this weapon idea is for guild members who aren't so combat oriented(such as the roles I discussed previously) but needs a relatively simple weapon to use when they're put into combat situations.
