Firearms in Middle-Earth (Pathfinder)

Rare Guns:

Firearms are rare; advanced firearms, the Gunslinger class, and archetypes that use the firearm rules do not exist. Firearms in Middle-Earth are treated more like magic items—things of wonder and mystery—rather than like things that are mass-produced. Few know the strange secrets of firearm creation.

They are produced by small guilds, lone gunsmiths, dwarven clans.
—the secret is slipping out, and the occasional rare adventurer uses guns. Early firearms are available, but are relatively rare.

Early firearms are typically matchlock, wheellock, or flintlock weapons, and require finesse and care. Early firearms are muzzle-loaded, requiring a bullet and powder (or other special alchemical substances) to be shoved down the barrel before the weapon is fired. Early firearm ammunition can be loaded from a cartridge, but that cartridge is made of soft material (like paper or cloth) that is torn open so that the contents may be shoved down the barrel.



Amateur Gunslinger (Combat) (Can be taught by someone posessing this feat or a gunsmith)
Although you are not a gunslinger, you have and can use grit.

Prerequisite: You have no levels in a class that has the grit class feature.

Benefit: You gain a small amount of grit and the ability to perform a single 1st-level deed from the gunslinger deed class feature. At the start of the day, you gain 1 grit point, though throughout the day you can gain grit points up to a maximum of your Wisdom modifier (minimum 1). You can regain grit using the rules for the gunslinger’s grit class feature. You can spend this grit to perform the 1st-level deed you chose upon taking this feat, and any other deed you have gained through feats or magic items.



Gunsmithing (Only taught by other gunsmiths, usually dwarves)
You know the secrets of repairing and restoring firearms.

Benefit: If you have access to a gunsmith's kit, you can create and restore firearms, craft bullets, and mix black powder for all types of firearms. You do not need to make a Craft check to create firearms and ammunition or to restore firearms.

Crafting Firearms: You can craft any early firearm for a cost in raw materials equal to half the price of the firearm. At your GM’s discretion, you can craft advanced firearms for a cost in raw materials equal to half the price of the firearm. Crafting a firearm in this way takes 1 day of work for every 1,000 gp of the firearm’s price (minimum 1 day).

Crafting Ammunition: You can craft bullets, pellets, and black powder for a cost in raw materials equal to 10% of the price. If you have at least 1 rank in Craft (alchemy), you can craft alchemical cartridges for a cost in raw materials equal to half the price of the cartridge. At your GM’s discretion, you can craft metal cartridges for a cost in raw materials equal to half the cost of the cartridge. Crafting bullets, black powder, or cartridges takes 1 day of work for every 1,000 gp of ammunition (minimum 1 day).

Restoring a Broken Firearm: Each day, with an hour’s worth of work, you can use this feat to repair a single firearm with the broken condition. You can take time during a rest period to restore a broken firearm with this feat.
