Fantastic Fantasy Firearms
Firearms have long existed in the world. From early hand cannons to the iconic flintlock musket, firearms have played a pivotal role in early modern warfare. Whether your fantasy setting is inspired by intrigue and adventure of stories like The Three Musketeers or alchemical tinkering has brought forth the power of gunpowder to your world, this supplement serves to provide firearms as a powerful yet balanced ranged weapon.
Proficiency in Firearms
Firearms are considered their own category of weaponry and thus proficiency is required to add your proficiency bonus to attack rolls. By default, certain classes and subclasses are assumed to grant firearms proficiency or limited proficiency in certain ones.
Ammunition
All firearms utilize the default ammunition within the Dungeon Master's Guide, referred to as bullets which are equivalent to the renaissance bullets found in the Dungeon Master's Guide. The Blunderbuss is capable of firing improvised ammunition at the discretion of the Dungeon Master.
Properties & Attachments
Covert
You have advantage on stealth checks to conceal this weapon.
Misfire
Whenever you make an attack roll with a firearm that is equal to or lower than the weapon's Misfire score, the weapon misfires and jams. The attack automatically misses and the weapon must be repaired before it can be fired again.
Repairing a firearm requires spending an action to try and repair the weapon with Tinker's Tools. The check DC is equal to 8 + the Misfire score of the weapon.If the check fails, the weapon breaks and must be repaired out of combat for a quarter of the cost of the weapon. A firearm's Misfire score increases by one when used by creatures not proficient in the firearm.
Scatter
When you fire this weapon, an attack is made simultaneously against a second creature or object within five feet of the targeted creature or object. If there are multiple creatures or objects, you may designate which is the secondary target.
Special: Bayonet
The bayonet is a long, thin blade designed to fit on the end of an Arquebus, Blunderbuss or Musket to allow the firearm to be used in close range melee combat. Attaching or detaching the bayonet is an object interaction. While the bayonet is attached, your weapon's maximum distance for firing without disadvantage is halved.
Variant Property: Reload
The weapon can be fired a number of time equal to its Reload score before you must spend one attack or one action to reload. You must have one free hand to load a fire arm.
This rule is more in line with Matthew Mercer's Gunslinger reload rules. All firearms in this supplement can be considered to have a Reload score of 1 unless otherwise specified.

Firearm Proficiencies by Class
Firearm proficiencies may be granted to classes rather than solely require a feat, fire-arm centric subclass or special training. The following table details how firearm proficiencies may be granted to different classes. Firearms refers to all weapons contained within this supplement while Pistols refers to the Pistol, Dragon Pistol, Dueling Pistol and Pocket Pistol.
If a subclass grants Martial Weapon Proficiencies, a Dungeon Master may elect to grant additional firearm proficiencies with the subclass if deemed thematically appropriate.
| Class | Proficiencies |
|---|---|
| Barbarian | Simple weapons, martial weapons, firearms |
| Bard | Simple weapons, hand crossbows, pistols, longswords, rapiers, shortswords |
| Cleric | Simple Weapons |
| Druid | Clubs, daggers, darts, javelins, maces, quarterstaffs, scimitars, sickles, slings, spears |
| Fighter | Simple weapons, martial weapons, firearms |
| Monk | Simple weapons, shortswords |
| Paladin | Simple weapons, martial weapons, firearms |
| Ranger | Simple weapons, martial weapons, firearms |
| Rogue | Simple weapons, hand crossbows, pistols, longswords, rapiers, shortswords |
| Sorcerer | Daggers, darts, slings, quarterstaffs, light crossbows |
| Warlock | Simple Weapons |
| Wizard | Daggers, darts, slings, quarterstaffs, light crossbows |
Variant Rule: Multiclassing and Firearms
If you meet the prerequisites to multiclass into a certain class and that class grants proficiency in Martial Weapons, you also gain proficiency in Firearms. Multiclassing into Barbarian, Fighter, Paladin and Ranger would thus grant proficiency in Firearms as would subclasses like the War Domain Cleric or Hexblade Warlock.
