Hi everybody, I wanted to know if anything was wrong with this build.
Double-Barreled Musket
This musket has two parallel barrels; each barrel can be shot independently as a separate action, or both can be fired at once as the same attack.
If both barrels are fired at once, they must both target the same creature or object, and the gun becomes wildly inaccurate, taking a –4 penalty on each shot. Each barrel of a double-barreled musket uses either a bullet and a single dose of black powder or an alchemical cartridge as ammunition.
Now the kicker comes with the Experimental Gunsmith
Innovations (Ex)
An experimental gunsmith starts play with one innovation she can make to her experimental firearms, selected from the list below. This innovation is a radical change to the typical design of a firearm, and comes with both additional benefits and noteworthy drawbacks. The experimental gunsmith can maintain only one experimental firearm modified with one or more innovations, as it requires constant adjustments and much of her time is spent maintaining the weapon. If the experimental gunsmith takes the Gunsmithing feat, she can create other firearms using a single innovation she knows (or add one innovation to an existing firearm), though such weapons become unreliable over time. The misfire value of such weapons increases by 1 for each week after its creation, although the experimental gunsmith can return the misfire rate to normal by spending 1 day maintaining the weapon and spending 50 gp in raw materials. For the purposes of crafting such firearms, each innovation is treated as the masterwork weapon quality (with a value of 300 gp).
At 5th level, and every four levels after that (9th, 13th, and 17th level), the experimental gunsmith learns one additional innovation from the list below. These represent constant and increasingly skilled tinkering with a single firearm in her possession, and when the experimental gunsmith gains an innovation, she may immediately apply it to her experimental firearm. Once an innovation has been selected, it cannot be changed.
This ability replaces gun training.
Expanded Capacity: The experimental gunsmith increases her firearm's capacity by one (generally by adding another barrel, depending on the weapon's design). She also increases its weight by 50%. Because of the complexity of increasing its capacity, her weapon is more prone to misfire, and its misfire value increases by 1 (this is in addition to any misfire increase if the weapon is made with the Gunsmithing feat).
Now if I apply the extended capacity to my double-barreled musket, does it become a triple-barreled musket? If it does is it still -4 per barrel or -8 per barrel?
I also use this with my Dragon Pistol and I want to know if I can double scatter-shot from it with this skill.
