Path of the Hellsworn

Some of those born into this world are marked by a darker power, selected by a fiend of the Nine Hells to release their unbridled rage through them. These chosen are called Hellsworn, channeling the rage from the deepest pits of the Nine Hells to scorch their enemies to darkened crispy husks of their former selves. Hellsworn use their ability to bend hellfire to their will to bolster their allies as well as themselves. The most powerful Hellsworn are able to even use their flames to pierce through even the mightiest creatures of the pit.

Hellfire Storm

3rd-level Path of the Hellsworn feature

Starting at 3rd level, you enrage into a swarm of green hellfire. Whenever you begin your rage, all creatures of your choice within a 10 ft. radius centered on you must succeed a Dexterity saving throw, the DC equals 8 + your proficiency bonus + your Constitution modifier. On a failed save, the creature receives 1d6 + half your barbarian level rounded down in fire damage. On a successful save, the creature takes half damage, and if a creature ends their turn within the radius, they must repeat the saving throw.

Infernal Engine

6th-level Path of the Hellsworn feature

At 6th level, your hellfury channels generations of power, allowing you to bend outer fire to fuel your own inner flame. As a reaction to an allied creature within your Hellfire Storm receiving fire damage, you can reduce the damage by 1d4 + your Constitution modifier. You can then gain a number of temporary hit points equal to the damage reduced. Additionally, as an action, you can touch a flammable object that isn’t being worn or carried by anyone else and set it on fire.

You can use this feature a number of times equal to your Constitution modifier (a minimum of once). You regain all expended uses when you finish a long rest.

Fiendish Rally

10th-level Path of the Hellsworn feature

At 10th level, you've learned to weave your hellfire to empower your allies. As a bonus action, you release Hellfire around you to empower your allies. Up to ten other creatures of your choice within 60 feet of you that you can see, can gain a number of temporary hit points equal to 2d8 + your Constitution modifier, and they can move their speed as a reaction without provoking attacks of opportunity.

Once you use this feature, you can’t use it again until you finish a long rest.

Dark Legacy

14th-level Path of the Hellsworn feature

At 14th level the power of your infernal communion connects to your soul, causing your flames to wreathe black, and thus becoming too intense for even the mightiest of the pit. Whenever you roll fire damage, you can treat any 1 on a damage die as a 2, and fire damage you deal ignores fire resistance and immunity. Additionally, you gain immunity to fire damage.
