Evil Tides of Saltmarsh features some pretty unique gameplay elements. One of those is firearms and other, "piratey" equipment.

• Firearms and the smokepowder that powers them is an invention of Lantan an Island Nation far to the south. They have kept the secrets of this technology to themselves for many years, but recently, those secrets have made their way north.
• Fire Firearms are all considered martial weapons.
• Firearms do great damage.
• Reloading a firearm requires your object interaction. Most firearms only hold a single shot at a time making multiple shots per round very difficult without enhanced equipment or special training.
• Firearms can misfire
• Firearms should not get wet.
