Path of the Pyromaniac

The Path of the Pyromaniac is born through an innate desire for consumption, as the barbarian burns everything in its way until all is but ash. Your rage manifests as an insatiable flame deep inside your being, allowing you to imbue your rage with this primal fire.

Most consider a pyromaniac to be akin to smoke-powder: a great asset in battle, while also being a dangerous tool with a hair-trigger. They are treated with extreme caution, lest their eternal hunger engulf their surroundings.

Inner Fire

Starting when you choose this path at 3rd level, you can wreathe your body in arcane flame when you rage. If you do so, for the duration of your rage you suffer fire damage equal to your Strength modifier at the start of each of your turns, but receive an equal bonus to your attack rolls and damage for melee attacks equal to the damage suffered. This damage ignores resistances and immunities you possess.

Fuel The Fire

Beginning at 6th level, your rage is accompanied by intense wildfire. At the start of your turn, all adjacent creatures to you take fire damage equal to the Strength modifier.

Scorching Inferno

Beginning at 10th level, you can use your action to expand your flames. When you do so, all creatures in a 10-foot-radius must succeed on a Dexterity saving throw (DC equal to 7 + your proficiency bonus + your Constitution modifier). A target takes 4d6 fire damage on a success or half as much on a failure. You instantly succeed on the saving throw, but cannot reduce the damage suffered further beyond this point through any means.

Immolation

Starting at 14th level, when you fall to 0 hit points, you can use your reaction to instantly burn into flames, dealing fire damage equal to 10d10 + your Constitution score + your level to all creatures in a 20-foot-radius around you. After using this ability, you instantly suffer 1 failure to your death saving throw and one level of exhaustion.
