Blade Whip. This weapon appears as a serrated curved sword, but the blade can be extended into a slashing chain whip. Attacks made with the whip deal 1d4 slashing damage and have a reach of 10 feet.

Blunderbuss, Double. This weapon fires two slugs with each attack (reflected in the damage). It has a cartridge size of 2, but both shots are consumed in a single attack. If a cartridge only has one piece of ammunition, the weapon deals only 2d6 damage.

Blunderbuss, Howler. This blunderbuss model fires a single slug with greater range.

Blunderbuss, Spreader. Whenever you hit a creature with this weapon, each creature within 5 feet of that creature (or a 5-foot section of your choice on it if it is Large or larger) must make a Dexterity saving throw against your combined attack roll. If the save is failed, the creature takes 2d4 slashing damage.

Clockwork Saw. This weapon infuses rotating cogs and serrated blades to rend flesh and bone. Many are similar in shape to an axe, but some feature elongated sword-like saws sometimes referred to as chain swords. Regardless of whether it is held in one or two hands, its damage remains the same.

Crossbow, Repeating. A cartridge-slotted crossbow loaded by a lever..

Fire Lance. This polearm acts much like a pike, but features a chamber along the point that contains a charge of boom powder. When you hit a creature with this weapon, you can activate this blast and deal an additional 2d6 fire damage. After using this feature, the weapon must be reloaded to use it again.

Flamer. This handheld device spews flames in a 10-foot cone. Make a single attack roll and apply the result against each target within the cone. The flamer is loaded with a tank which typically contains a special blend of alchemical fire.

Hand Cannon. This heavy firearm shoots a heavy spherical round. In order to attack with this weapon, you can’t have moved during your turn, and after firing this weapon your movement speed is reduced to 0 until the end of your turn.

Lash Pole. A club with a spring-loaded spear point. The user can opt to use this as a club and instead deal 1d4 bludgeoning damage on a successful attack.

Pistol, Cartridge. This one-handed firearm has a small cartridge

Pistol, Single Shot. A hand-loaded pistol.

Punch Hammer. This weapon uses gears and springs to smash a target when swung for extra impact. Alternate models can attach a puncturing blade to deal piercing damage instead.

Rifle, Cartridge. A rifle with an easy to slot cartridge to fire multiple shots before reloading.

Rifle, Single Shot. A basic rifle that requires reloading after each shot.

Rifle, Zoomer. This rifle is designed to make long range attacks. It includes a small sized spy glass configured to allow the user to precisely see targets when lining up the shot.

Slug Thrower. An easy to use ranged slug dispenser that fires in an arc. It often is used to disperse alchemical poultices on the battlefield. It can be loaded with powders or makeshift flak at the DM’s discretion.

Speargun. This is a type of crossbow that fires short, heavy bolts. It suffers no penalties when used underwater or in similar environments.

Switch Staff. This trick weapon appears as a quarterstaff with grooves along its shaft. With a simple motion, blades can spring from the grooves allowing the wielder to change its damage type to slashing. The weapon can be changed with each attack as part of the attack.

Wrist Darts. This special bracer has a trio of mechanisms in it that can fire a single dart each without requiring the user to change weapons. The wrist dart doesn’t require the use of the wielder’s hand, freeing it to hold another weapon, tool, or provide the somatic and material components for casting a spell.


Cartridge. This weapon requires ammunition loaded into a case that allows the weapon to fire the number of shots indicated before it must be reloaded. Reloading the weapon requires either a bonus action or action. If you have a feature that allows you to ignore the loading property , the cartridge can be replaced without an action unless the weapon has the slow loading property.

Ingenuity. When making attacks with an ingenuity weapon, you use your choice of Strength or Intelligence modifier for the attack and damage rolls. You must use the same modifier for both rolls.

Slow Loading. Due to the mechanism to load the weapon it requires a bonus action or action to reload. Features which affect the loading property don’t affect the slow loading property.

Users typically carry a number of cartridges to speed up the reloading procedure. A cartridge requires as much space as a flask. To refill a cartridge, you must use your action and can’t move during that turn. You must have appropriate ammunition for the weapon.
