Barbarian: Path of Flame

Your rage is a violent inferno of infinite flames, brought forth directly from the only source of such power that could sate you: The Elemental Plane of Fire. You may have gained this power from time spent upon the plane, or from your heritage as a fire genasi, or even from being burned and absorbing the flame into yourself by sheer force of will. Whatever the case, your rage manifests as a vulgar and unstoppable force of nature, to be feared and respected by allies and enemies alike.

Fiery Rage At 3rd level, when you choose this path, your rage appears as a visible, fiery aura around you. While you are raging, you have resistance to fire damage and you can add double your proficiency bonus to Charisma (Intimidation) checks made against creatures that can see you.

Burning Blade Even when left naked and unprepared, you have the power of your fiery spirit as your weapon. When you choose this path at 3rd level, you can summon forth a single fiery weapon in your free hand as a bonus action. The weapon can take the shape of any melee weapon you designate, and has the same properties of that weapon. If you let go of the weapon, it disappears, but you can bring forth the blade again as a bonus action. The weapon deals fire damage, instead of its normal damage type, and sheds light in a 10-foot radius and dim light for an additional 10 feet.
