Arcane Firearm Proficiency

Starting when you choose this archetype at 3rd level, you gain proficiency with magic firearms, allowing you to add your proficiency bonus to attacks made with magic firearms.

Arcane Gunsmith

Upon choosing this archetype at 3rd level, you gain proficiency with Tinker’s Tools. You may use them to craft ammunition at half the cost, repair damaged firearms, or even draft and create new ones (DM’s discretion). Some extremely experimental and intricate firearms are only available through crafting.

Arcane Firearm Properties

Arcane 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

Arcane firearms differ from traditional firearms in that they use magic in place of ammunition. This still requires an action to "recharge" the weapon before firing again. This action is simply called "Reload".

Firearms

1. Arc Rifle; The signature weapon of the Arc Gunner, the Arc Rifle has the best range and power of the two weapons in the Arc Gunner's arsenal. The Arc Rifle can be fired up to five times before it requires "reloading". Certain actions may consume all ammunition. Reload Score 5
2. Mana Revolver; The Mana Revolver is a more compact counterpart to the Arc Rifle more easily held in hand but has only half the range and accuracy of the Arc Rifle. Reload Score 6

Adept Marksman

When you choose this archetype at 3rd level, you learn to perform powerful trick shots to disable or damage your opponents using your firearms.

Trick Shots. You learn two trick shots of your choice, which are detailed under “Trick Shots” below. Many maneuvers enhance an attack in some way. Each use of a trick shot must be declared before the attack roll is made. You can use only one trick shot per attack.

You learn an additional trick shot of your choice at 7th, 10th, 15th, and 18th level. Each time you learn a new trick shot, you can also replace one trick shot you know with a different one.

Saving Throws. Some of your trick shots require your targets to make a saving throw to resist the trick shot’s effects. The saving throw DC is calculated as follows:

   Trick Shot save DC = 8 + your proficiency bonus + your Dexterity modifier

Quickdraw

When you reach 7th level, you add your proficiency bonus to your initiative. You can also stow a firearm, then draw another firearm as a single object interaction on your turn.

Rapid Repair

Upon reaching 10th level, you learn how to quickly attempt to fix a jammed gun. You can spend a grit point to attempt to repair a misfired (but not broken) firearm as a bonus action.

Lightning Reload

Starting at 15th level, you can reload any firearm as a bonus action.

Vicious Intent

At 18th level, your firearm attacks score a critical hit on a roll of 19-20, and you regain a grit point on a roll of 19 or 20 on a d20 attack roll.

Hemorrhaging Critical

Upon reaching 18th level, whenever you score a critical hit on an attack with a firearm, the target additionally suffers half of the damage from the attack at the end of its next turn.
