Gunsmith Craft lets you design, craft, repair, and even improvise firearms and gunpowder-based weapons like bombs and grenades. In addition to this, you become able to unjam a weapon with a greater degree of success as well as having a better knowledge of how to use firearms more accurately and effectively.

Attribute: The attribute for tests related to Gunsmith Craft is Wisdom.

Synergies: Using the Gunsmith Set, you can use this Craft with the following skills, enabling some effects:

Arcana, History, Investigation. Your mastery with firearms grants you additional information, such as the possibility of a firearm's origin, techniques used to make it, and even deductions regarding its arcane capabilities.

Gunsmith Set

With the Gunsmith Set you can create firearms and ammunition of the most different types, including flintlock pistols, revolvers, among others. For this you need to have a space to heat the metal, melt it to create pipes and a press to encapsulate ammunition.

Content: A Gunsmith's Set includes molds, tweezers, charcoal, metal scraps, gunpowder and ammo press.

Firearm Modifications:

In addition to the crafting formulas, firearms have modification formulas, which are applied to some of the parts that make up a firearm, meaning that each part can only have one modification at a time, these parts being Barrel, Alloy and Reload. The “Extra” category generally refers to accessories and has specific rules.

Modification formulas have an additional descriptor, Part, which refers to which part of the firearm is modified. The words that follow this descriptor refer to which types of firearms these modifications can be applied to; in the absence of any words, the modification can be applied to all types of firearms. All modification formulas require the part to be modified as a component.

You can only apply modification formulas to weapons that you can craft, and although it falls under the Firearms category, a Flamethrower has its own rules and cannot be modified using Firearms modification formulas.

Ex. A pistol may have a barrel modification, with a rifled barrel, an alloy barrel with a light alloy barrel, and a reload barrel with a memory barrel. Additionally, some modifications are special, such as “Interchangeable” which allows a weapon to have its rifled barrel replaced with another barrel with an exhaust barrel modification. A bonus action is required to perform the barrel swap.

Repairing a Firearm:

Firearms Repair
Tier	Repair DC
1	17
2	19
3	21
4	23
5	25
6	27

To repair a weapon that has suffered some damage to its integrity, a craft roll with a DC based on the type of damage and the weapon's Tier is required. In some cases, in addition to the roll, the Gunsmith's set and a value in GP in replacement parts are required.

Jammed

A jammed firearm cannot fire until it is repaired. A jammed firearm means that its internal mechanism has suffered some problem or misalignment, rendering the firearm incapable of firing until this is fixed.

Unjamming a Firearm in Combat:

Unjamming a firearm requires at least one action. The creature with the weapon must make a Gunsmith skill check with a DC based on the weapon's tier. On a success, the weapon is unjammed and can be used normally; on a failure, the weapon remains jammed; and on a critical failure, the weapon is rendered useless.

Unjamming a Firearm Out of Combat:

Unjamming a firearm out of combat can be done in a number of minutes based on the weapon's Tier with the DC reduced by 2.

Unusable

Firearms are subject to problems. An unusable weapon cannot fire until it is repaired and cannot be repaired during combat. A weapon that has become unusable has suffered some internal damage that misaligns some of its components and requires complete maintenance to be used again.

Repairing

It cannot be done during combat, it requires an amount of time equal to 5 minutes for each Tier of the weapon (5 to 30m). On a failure, it remains unusable, on a critical failure it is broken.

Broken

When a firearm is broken, not only will it not be able to fire until it is repaired, but repairing it will require some part to be replaced or remade. Magical weapons can only be broken by extremely powerful effects or if they are extensively damaged by an antimagic field or similar.

Fixing a Firearm

To repair a firearm the time varies according to the damage caused, it is necessary to spend time and GP to replace the part in question. During the Craft roll, a success means that the weapon has been repaired and can be used normally, on a failure it remains broken and on a critical failure it is destroyed.

Destroyed

A destroyed weapon cannot be repaired, the shooter can use the Craft and Gunsmith tools to try to extract parts to create a new weapon or repair an existing one.

Recovering Parts of a Weapon

The gunsmith must make a craft roll with a DC based on the Weapon Tier. On a success, he can recover some parts of the weapon worth 10% of its value. On a failure, the parts are lost, and on a critical failure, the gunsmith receives 1d4 damage (based on the weapon type) per weapon Tier.
