Gunbreaker

Historically, Gunbreakers were employed as Queen Gunnhildr's personal guard. Known as "Gunnhildr's Blades", these warriors used their signature weapon to wade through to their enemy's back line, as well as subdue archers and gunners.

Today, Gunbreakers are front-liners that wield a gunblade into battle. Unlike the standard models wielded by specialists, a Gunbreaker's gunblade uses magically charged rounds that, when fired, shoots powder that coalesces into into a magical effect that protects the wielder and its allies.

The Gunblade

A gunblade is a sword or other melee weapon with a firing mechanism, much like a pistol or a revolver, that serves as the blade's hilt. Despite its name, a gunblade cannot be used as a firearm - this means it does not fire projectiles, and can only be used in melee combat. Instead, the "firing" of a gunblade consumes an infused Munition, and induces a tremor throughout the blade, causing it to deal additional effects to whatever it strikes. Most Gunbreakers like to name the blades they make, and give them their own personal flair.

 

Arms Smith

You have learned how to modify weaponry to incorporate gunfire into their function. You gain proficiency in Smith's Tools. When you craft something with Smith's Tools, you can create something in half the time it usually takes.

Moreover, you can spend 1 hour to fuse a melee weapon and a non-magical firearm (found within page 268 of the Dungeon Master's Guide) together into a hybrid weapon, hereafter known as a Gunblade. You can maintain up to two Gunblades at a time, and only you are proficient with them.

A Gunblade retains the properties of the melee weapon used in its creation, and cannot be used as a ranged weapon. A Gunblade holds a number of infused Munitions equal to the Reload value of the firearm used in its creation, and requires an Action to reload. Its weight is equal to the combined weight of the two weapons used to create it.

Munitions

Starting at 3rd level, you know how to work your magical expertise into creating Munitions.

While you have your Smith's Tools in hand, you can create a number of Munitions equal to 2d4 + your Wisdom modifier over the course of a short or long rest - you must have firearm ammunition for the total number of Munitions you create. The total number of Munitions you create can be of any combination of known Munition options you have (see below). The size of the dice you roll to create Munitions increases as you gain levels in this class: you roll 2d6 at 7th level, 2d8 at 14th level, 2d10 at 17th level, and 2d12 at 20th level.

Once per turn, you can choose to consume one of your infused munitions through your Gunblade to add a special effect to the next weapon attack you make, determined by the kind of Munition you expend.

You learn three Munitions options of your choice, as detailed below. You gain an additional Munitions option when you reach 7th, 10th, 15th, and 18th level in this class.

Aurora Shell

When you hit with an attack while infused with this Munition, the target must make a Wisdom saving throw, the DC of which is equal to 8 + your Proficiency bonus + your Wisdom modifier.

At 7th level, you can expend one of your Munitions when you are in danger.

Whenever you take damage in combat, you can use your reaction to expend one of your infused Munitions in your Gunblade, and gain resistance to the triggering type of damage until the start of your next turn. If the triggering damage has multiple types, you choose which type of damage you gain resistance to.

Continuous Fire

Starting at 10th level, you can consume up to two infused Munitions per turn before you hit with an attack. You can apply each effect only once, and each different effect must be applied to a different weapon attack.

Whenever you take damage in combat, you can use your reaction to consume two infused Munitions, and gain Immunity to the triggering damage until the end of your next turn. If the triggering damage has more than one type, you decide which damage type you gain immunity to. 

You can use this feature twice, and regain any expended uses when you finish a long rest.
