Firearm Properties

Firearms are a new and volatile technology, and as such bring their own unique set of weapon properties. Some properties are followed by a number, and this number signifies an element of that property (outlined below). These properties replace the optional ones presented in the Dungeon Master’s Guide. Firearms are ranged weapons.

Reload. The weapon can be fired a number of times equal to its Reload score before you must spend 1 attack or 1 action to reload. You must have one free hand to reload a firearm.

Misfire. Whenever you make an attack roll with a firearm, and the dice roll is equal to or lower than the weapon’s Misfire score, the weapon misfires. The attack misses, and the weapon cannot be used again until you spend an action to try and repair it. To repair your firearm, you must make a successful Tinker’s Tools check (DC equal to 8 + misfire score). If your check fails, the weapon is broken and must be mended out of combat at a quarter of the cost of the firearm. Creatures who use a firearm without being proficient increase the weapon’s misfire score by 1.

Explosive. Upon a hit, everything within 5 ft of the target must make a Dexterity saving throw (DC equal to 8 + your proficiency bonus + your Dexterity modifier) or suffer 1d8 fire damage. If the weapon misses, the ammunition fails to detonate, or bounces away harmlessly before doing so.

Ammunition

All firearms require ammunition to make an attack, and due to their rare nature, ammunition may be near impossible to find or purchase. However, if materials are gathered, you can craft ammunition yourself using your Tinker’s Tools at half the cost. Each firearm uses its own unique ammunition and is generally sold or crafted in batches listed below next to the price.

 

Arcane Bullets

You are able to use your knowledge of firearms and your tinker’s tools to put magic into your bullets. You’re able to make 20 bullets magical over a long rest, and 10 bullets magical over a short rest. Additionally, you can use your action during combat to magically infuse a bullet with magic properties giving it 1d4 damage of your choice besides slashing, piercing, and bludgeoning. This can only be done an amount of times equal to your Intelligence modifier per long rest. When you infuse magic into your bullets over a long or short rest, you can give the set bullets one of the effects from the options offered by this feature. You don’t have to stick to one effect, you do another long or short rest you can choose to give your new bullets different effects.
