Path of the Blunderbuss

This expansion introduces the Path of the Blunderbuss, a Primal Path option available to barbarian characters at 3rd level.

Members of the Path of the Blunderbuss often claim that it represents some great spiritual journey, but for many, deep down, they just can't escape the love of things that go BOOM! Filled with the stench of gunpowder and slightly smouldering from the latest explosion, a barbarian of this primal path masters the use of heavy-duty firearms in close-quarters violence.

Flint and Steel

Starting when you choose this path at 3rd level, you can use Strength instead of Dexterity for attack and damage rolls made with muskets, shotguns, and any firearm with the heavy property.
While raging, when you make a ranged weapon attack using Strength with a firearm, you gain the same bonus to the damage roll as if you had made a melee weapon attack. You can only gain this benefit if you are within 10 feet of your target.

Point Blank Shot

Also starting at 3rd level, while you are raging you do not suffer disadvantage on ranged weapon attack rolls if a hostile creature is within 5 feet of you.

Innured to Gunpowder

Beginning at 6th level, you are innured to the explosive volatility of gunpowder. You cannot be deafened. While you are raging, you have resistance to fire damage.When you reach 14th level, you have immunity to fire damage while raging, instead of resistance.

Thundering Blast

Beginning at 10th level, you can cause an explosion of gunpowder in the barrel to unleash an especially destructive shot with your firearms. As an action while wielding a musket, shotgun, or any firearm with the heavy property, you can release an explosion in a 15-foot cone centred on yourself. Each creature in that area must make a Dexterity saving throw (DC equal to 8 + your proficiency bonus + your Strength modifier), taking 2d8 fire damage and 2d8 thunder damage on a failed save, or half as much damage on a success. The explosion releases a boom audible out to 300 feet.
You can use this feature a number of times equal to your Constitution modifier (a minimum of once).

When you reach 18th level, the damage for this feature increases to 3d8 fire damage and 3d8 thunder damage.

Vicious Shot

Starting at 14th level, when you hit with a ranged weapon attack with a musket, shotgun, or any firearm with the heavy property, you can deal 1 additional die of damage.
