Item: Big Boom Gun
Developed by a goblin weaponsmith who missed the "hand" part of "hand cannon," this comically oversized gun has a heavily reinforced barrel and is loaded with a worrisome quantity of gunpowder. This hand cannon is a martial weapon instead of a simple weapon. It has the fatal d12 trait and a range increment of 20 feet. It also has the following modified critical failure condition.
Critical Failure The attack misses, the weapon misfires, and you take 1d12 fire damage as it explodes in your face.
Trait Effects
Cobbled: This firearm is cobbled together and likely to misfire. No matter how well you upkeep it, on a failed attack roll, the attack misses and you must roll a DC 5 flat check. If you fail this check, the weapon misfires.
Fatal: The fatal trait includes a die size. On a critical hit, the weapon’s damage die increases to that die size instead of the normal die size, and the weapon adds one additional damage die of the listed size.
Goblin: A creature with this trait is a small, frantic goblinoid. Goblins tend to have darkvision. An ability with this trait can be used or chosen only by goblins. A weapon with this trait is created and used by goblins.
Modular: The weapon has multiple configurations that you can switch between using an Interact action. Typically, switching between configurations of a modular weapon allows it to deal different types of damage (listed in the trait, such as “modular B, P, or S”), though it's possible for a modular weapon's description to list more complicated configurations.
Critical Specialisation Effects
Certain effects can grant you benefits when you make a Strike with certain weapons and get a critical success. This is called a critical specialisation effect. The exact effect depends on which weapon group your weapon belongs to, as listed below. You can always decide not to add the critical specialisation effect of your weapon.
Firearm: The target must succeed at a Fortitude save against your class DC or be stunned 1.
