Pepperboxes are multi-barreled firearms designed for rapid consecutive shots. They provide high firepower and quick follow-up attacks, ideal for chaotic battles. Though heavier and bulkier than standard pistols, their ability to fire multiple rounds before reloading makes them valuable for sustained engagements and crowd control.
You can use a weapon that has the Ammunition property to make a Weapon Ranged Attack Roll only if you have Ammunition to fire from the weapon. Each time you Attack with the weapon, you expend one piece of Ammunition. Drawing the Ammunition from a Quiver, case, or other container is part of the Attack (you need a free hand to load a one-handed weapon).
