Gunslinger

Most warriors and combat specialists spend their years perfecting the classic arts of swordplay, archery, or polearm tactics. Whether duelist or infantry, martial weapons were seemingly perfected long ago, and the true challenge is to master them.
However, some minds couldn't stop with the innovation of the crossbow. Experimentation with alchemical components and rare metals have unlocked the secrets of controlled explosive force. The few who survive these trials of ingenuity may become the first to create, and deftly wield, the first firearms.
This archetype focuses on the ability to design, craft, and utilize powerful, yet dangerous ranged weapons. Through creative innovation and immaculate aim, you become a distant force of death on the battlefield. However, not being a perfect science, firearms carry an inherent instability that can occasionally leave you without a functional means of attack. This is the danger of new, untested technologies in a world where the arcane energies that rule the elements are ever present.
Should this path of powder, fire, and metal call to you, keep your wits about you, hold on to your convictions as a fighter, and let skill meet luck to guide your bullets to strike true.

Gunslingers around the Azure Sea

The discovery of Blackpowder has accelerated the use of firearms across the The Azure Sea in recent years, though Gunslingers are still an uncommon enough sight.
Only the very top-of-the-line ships in the Imperial Navy carry cannons, and the powder itself is not easy to obtain or to handle. Still, a select few have accepted the risks involved, and are still looked on with wary curiosity by most.

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 an action (or an attack) 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 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 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 5ft 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 in batches listed next to the price.

Pistol	150 sp	1d10 piercing	3	range 60/240	4	1	4 sp for 20 ammo, 2 sp to craft

Trickshots

Gunslingers can make the following Trick Shots using their Grit Points.

Name	Grit Points	Description
Bullying Shot	1	You can use the powerful blast and thundering sound of your firearm to shake the resolve of a creature. When making a Charisma (Intimidation) check, you can expend one grit point to gain advantage on the roll.
Dazing Shot	1	When you make a firearm attack against a creature, you can expend one grit point to attempt to dizzy your opponent. On a hit, the creature suffers normal damage and must make a Constitution saving throw or suffer disadvantage on attacks until the end of their next turn.
Deadeye Shot	1	When you make a firearm attack against a creature, you expend one grit point to gain advantage on the attack roll.
Disarming Shot	1	When you make a firearm attack against a creature, you can expend one grit point to attempt to shoot an object from their hands. On a hit, the creature suffers normal damage and must succeed on a Strength saving throw or drop 1 held object of your choice and have that object be pushed 10ft away from you.
Forceful Shot	1	When you make a firearm attack against a creature, you can expend one grit point to attempt to trip them up and force them back. On a hit, the creature suffers normal damage and must succeed on a Strength saving throw or be pushed 15ft away from you.
Piercing Shot	1	When you make a firearm attack against a creature, you can expend one grit point to attempt to fire through multiple opponents. The initial attack gains a +1 to the firearm's misfire score. On a hit, the creature suffers normal damage and you make an attack roll with disadvantage against every creature in a line directly behind the target within your first range increment. Only the initial attack can misfire.
Violent Shot	1+	When you make a firearm attack against a creature, you can expend one or more grit points to enhance the volatility of the attack. For each grit point expended, the attack gains a +2 to the firearm's misfire score. If the attack hits, you can roll one additional weapon damage die per grit point spent when determining the damage.
Winging Shot	1	When you make a firearm attack against a creature, you expend one grit point to attempt to topple a moving target. On a hit, the creature suffers normal damage and must make a Strength saving throw or be knocked prone .
