Benefits
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.
