Combination weapons combine the functionality of melee weapons and ranged weapons in unique or unusual ways. A combination weapon has a ranged form or usage and a melee weapon form or usage. The combination weapons table lists the ranged weapon statistics first and the melee weapon statistics indented beneath, just above the ammunition. Switching between the melee weapon usage and the ranged weapon usage requires an Interact action. However, if your last action was a successful melee Strike against a foe using a combination weapon, you can make a ranged Strike with the combination weapon against that foe without fully switching to the ranged weapon usage, firing the ranged weapon just as you hit with the melee attack. In this case, the combination weapon returns to its melee usage after the ranged weapon Strike.

Since a combination weapon is one weapon with two usages, both usages share any fundamental runes. You can put a property rune on a combination weapon as long as it's appropriate for either of the two usages, but if only one of the usages meets the property rune's requirements, the effects of the property rune only apply for that usage. For instance, a vorpal axe musket only applies the vorpal property rune when you're using it as an axe. Due to their complexity, combination weapons can't have another weapon, such as a bayonet or reinforced stock, attached to them.

These weapons smash as much as puncture. When determining a creature's resistance or immunity to damage from this weapon, use the weaker of the target's resistance or immunity to piercing or to bludgeoning. For instance, if the creature were immune to piercing and had no resistance or immunity to bludgeoning damage, it would take full damage from a concussive weapon. Resistance or immunity to all physical damage, or all damage, applies as normal.

Critical fusion is a trait for combination weapons that grants you two additional options for the critical specialization effect when using the combination weapon's melee version to make a melee attack while the ranged weapon is loaded. If you choose to use one of them, it replaces the melee usage's normal critical specialization effect.

First, if the ranged weapon is a firearm, you can discharge it to create a loud bang and concussion, using the critical specialization effect for firearms instead of the melee weapon group's critical specialization effect. Second, you can choose to discharge the ranged weapon to increase the critical hit's momentum or shoot the foe as you attack in melee, dealing 2 additional damage per weapon damage die. Both of these options discharge the ranged weapon, which typically means you have to reload it before firing it again.

A kickback weapon is extra powerful and difficult to use due to its high recoil. A kickback weapon deals 1 additional damage with all attacks. Firing a kickback weapon gives a –2 circumstance penalty to the attack roll, but characters with 14 or more Strength ignore the penalty. Attaching a kickback weapon to a deployed bipod, tripod, or other stabilizer can lower or negate this penalty.

Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.

A versatile weapon can be used to deal a different type of damage than that listed in the Damage entry. This trait indicates the alternate damage type. For instance, a piercing weapon that is versatile S can be used to deal piercing or slashing damage. You choose the damage type each time you make an attack.
