Path of the Scorching Inferno

You can channel your very anger into pure heat and energy.

Boiling Blood

At 3rd level: When you enter your rage by using a bonus action you can cause your body to heat up making your skin burn to the touch dealing 1d4 fire damage per turn that they are touching them (2d4 at 5th level, 3d4 at 7th level, 4d4 at 10th level)

(Also as part of your rage) You also emit 15 feet of a dim light making dim areas bright and dark areas dim.

Spreading Fire

Also at 3rd level: when you add your rage damage modifier to a damage roll, you can change this additional damage type to fire damage. If you score a critical hit then you may change all of your weapon damage to fire damage.

Flaming Grandure

At 6th level: You can engulf any handheld item you touch with flames as a bonus action. You may do this a number of times per short rest equal to your rage damage modifier. (This causes weapons to do an additional 1d6 fire damage upon a hit) if anyone other than you touches or picks up the weapon or item then they take the 1d6 fire damage

Engulfed

At 10th level: As you rage your body becomes engulfed in flames as you become immune to fire damage as long as you are raging

Chaos Inferno

At 14th level: you can explode into a ball which is the equivalent of casting fireball on yourself, you may do this a number of times per short rest equal to half of your Rage damage modifier. This catches the floor in the radius of the explosion on fire.
