Item: Piercing Wind

Combination: 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.

Concussive: 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.

Fatal Aim: It’s possible to hold the stock of this weapon under one arm so you can fire it with a single hand, but if you use both hands, the weapon can make fatal attacks. When you wield the weapon in two hands, it gains the fatal trait with the listed damage die. Holding the weapon underarm stably enough to fire is significantly more complicated than just releasing one hand from the weapon, so switching between the two grips requires its own Interact action, not via Releasing or as part of reloading.
