Path of Flame

Rage is a fire within the soul of a barbarian. Some barbarians take this literally. They embraces the inner flame until it erupts out of their bodies as a firestorm. These barbarians heat their weapons, blast you with flames, and even erupt in flames themselves while in their berserker rage all the while being immune to the very fires they control. Barbarians are dangerous enough let alone when they can drown you in flame.

Hot Tongue

Starting when you choose this path at 3rd level, you gain the ability to speak Ignan, the language of fire elementals.

Dragon's Flame

Starting when you choose this path at 3rd level, you can blast fire out of your mouth in a 15 foot cone in front of you as an action. Each creature in the area must make a dexterity saving throw. Creatures take 2d6 fire damage on a failed saving throw or half damage on a successful one. This damage is increased by 1d6 each time you gain a path feature at 6th, 10th, and 14th levels.

This ability can't be used again until the end of a short or long rest.

Hot Iron

Beginning at 6th level, you heat your weapon to be searing hot. Whenever you strike an enemy, they take a bonus 2d6 fire damage. While you remain immune to your weapon's heat, if an ally touches the hot weapon, they too will suffer the 2d6 fire damage.

No Sweat

Beginning at 10th level, your adherence to your primal path, gives you immunity to all fire damage.

Avatar of Flame

Starting at 14th level, when you rage, you burst into flames for the duration of the rage. Each creature you choose within 5 feet of you must make a dexterity saving throw. Enemies take 1d6 fire damage on a failed save or half as much on a successful one from the eruption of flames. Enemies within 5 feet of you beginning their turn must now make a constitution saving throw. Enemies take 1d6 fire damage on a failed save or half as much on a successful one. You can end the Avatar of Flame by ending your rage with a bonus action.
