"I hope you know that this thing isn't gonna work."

"Nah, it'll work. For sure!"

"...You had to make a four-legged stand for the thing to fire it without removing your own arm and it looks like something Primus has nightmares about."

"And he damn well should have nightmares about it! This thing will blow his damn head off!!"

-A couple of dumbasses

 A couple of punch drunk dumbasses got together over a weekend bender and somehow got their hands on some metal, machinery, andd half-rotted blueprints and got to work on a weapon to rival the fury of the gods.

Or something that would totally break and kill them both. Either one works.

But for some strange reason, by the will of the gods or by some sick stroke of pure luck, not only did they live, but they succeeded in their (un)holy endeavour. The result, the "Separatist."

The Separatist is a massive mostrosity of a weapon that is far more powerful than what should be possible. The weapon has the Heavy property and cannot be used by a Small creature by any degree. Medium creature must make use of the weapon's stand in order to use it properly and Large or bigger creatures can hold, aim, and fire the Separatist at disadvantage without the stand. The weapons does, however, come with a scope that gives advantage to all attacks made with the weapon.

The Separatist denies all previous rules of firearms, effectively rewriting them after it came into existance. 

Range: 6500/8200

Damage: Target must make a Constitution equal to the save DC of the user. On a success, the target takes 24d12 Piercing damage. This damage is regarded as magical and ignores resistance to Piercing damage. A target with immunity take half damage and all structures and objects take double damage. On a failiure, the target is turned into red mist and dies instantly, as if they have suffered the effects of the spell Power Word Kill (ignoring the 100 HP threshold. This had to be said because people are stupid.).

However, because of the power this weapon possess, it was promptly taken away from the two idiots be Asmodeus and there is only one way someone will be able to come into owning the Separatist. A quest that is to not be taken lightly and is not for the faint of heart. Firstly, one must amass a small fortune of 750,000 gold. Second, one must obtain the tortured soul of a Red Dracolich from Orcus, the Demon King of Undeath. Lastly, one must possess a willfully given fang of the Black Queen, Tiamat. Only after all of these items are possessed will Asmodeus allow an audience with him and a contest of Best of 9 Rock, Paper, Scissors will commence. If you win, you get the Separatist. Fail, and you will have to restart the journey to obtain the materials from the beginning. None of these materials can be obtained by the use of the Wish spell. Any attempt to do so will result in immediate deletion from reality.

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.
