Black Powder Domain

The gods of black powder are patrons to tinkerers, hunters, protectors, and conquerors. Black powder levels the playing field it can move mountains and empower the weak. Clerics of the black powder domain seek to spread the tenets of their gods through wondrous and explosive displays of force. Gods such as Gond, Hephaestus, Moradin, or Murlynd hold a special domain for firearms.

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.

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 unique ammunition and is generally sold or crafted in batches listed below next to the price.

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.

Masterwork. The weapon provides an additional +1 bonus to attack rolls. Additionally, when the firearm misfires, the user may use their reaction to roll a 1d6, on a 1 or 2 the misfire occurs as usual, on a roll of 3-6 the user is able to prevent the misfire.

Masterpiece. The weapon can be considered a work of art by other gunsmiths. The weapon provides an additional +1 bonus to attack and damage rolls made with the weapon. The misfire rating is reduced by 1 point. Additionally, when the firearm misfires, the user may use their reaction to roll a 1d6, on a 1 the misfire occurs as usual, on a roll of 2-6 the user is able to prevent the misfire.

Misfire. Whenever you roll an attack roll with a firearm and the result on the die is equal to or lower than a firearm’s Misfire score, the weapon misfires. The attack misses, and the firearm is in danger of breaking completely. You may spend an attack, or bonus action to clear the misfire (no check required), but if you do not, a second misfire will cause an explosion and break the weapon. This explosion deals the weapon’s listed damage to you and any creatures or objects within five feet.

Repairing a broken firearm, requires a short rest and an Intelligence (Tinker’s Tools) check (DC 10 + the firearm’s misfire score). On a success, the weapon is repaired and functional again; failure simply means you must spend another hour to attempt the repairs again.

Reload. A limited number of shots can be made with a weapon that has the reload property. A character must then reload it using an action or a bonus action (the character's choice). Alternatively, you may use your free action to stow your weapon in your other hand before reloading.

Scatter. When you fire a weapon with the scatter property at a target, you may simultaneously attack a second target that is within 5 feet of the first target. The second attack uses the same attack and damage rolls for both targets.

Crafting Munitions

Alchemical Cartridge. Fusing alchemy with black powder is a delicate process and can be created in one hour, as well as during a long or short rest. An Intelligence (Alchemist's Supplies) check must be made, you may produce a number of Alchemical Cartridges equal to the results of the check divided by 5 (minimum of 1).

Each alchemical cartridge requires 20gp worth of alchemical reagents.

Ammunition. Firearms that use the same type of ammunition are considered interchangeable between different firearms. Mundane ammunition is crafted by making a Dexterity (Tinker's or Smith's Tools) check. This can be done as light activity during a long rest, or during a short rest at disadvantage. The result of the check is the amount of ammunition the character is able to craft in that period of time.

Each individual ammunition consumes one dose of black powder when used and costs 2 silver pieces to craft.

Black Powder. The act of creating black powder is a tedious and process that involves the careful blending and combining of ingredients (usually in water, to reduce the risk of explosion), and then allowing the resulting cakes of powder to fully dry before seeing use. This process requires the use of Alchemist's Supplies and four hours of work, at the end of four hours the crafter must make an Intelligence (Alchemist's Supplies) check, with the resulting roll being the amount of doses the crafter is able to make. This method uses materials costing 1 silver piece per dose.

Bombs. Crafting bombs is a time consuming and delicate process that includes shaping an iron or glass shell, filling it with adequate powder and shrapnel, waxing a fuse, and then sealing it within the neck. A bomb may be created in one hour, as well as during a long or short rest with a successful DC 15 Dexterity (Tinker's Tools) check. On a result of 9-14 you fail to create a bomb and lose half the materials in the process. On a result less than 8, the bomb explodes as you are working on it.

Medic Rounds. During times of great necessity, specialist marksmen can be used to tactically deploy medical attention at range with minimal risk to themselves. Each round takes 8 hours and 25 gp of materials to craft. At the end of the 8 hours, the crafter must be make an Intelligence (Alchemy supplies or Herbalism Kit) check DC 14 and a Dexterity (Tinker's tools) check DC 14 to produce one round.
