Bonus Proficiency: When you choose this path at 3rd level, you gain proficiency in the Intimidation skill if you don't already have it. Additionally, you gain the Control Flames cantrip if you don't already know it, and it doesn't count against your number of cantrips known.

Ignited Rage: Starting at 3rd level, when you enter a rage, flames erupt around you, covering your body in a fiery aura. While raging, your melee attacks deal an additional 1d4 fire damage. Additionally, any creature that hits you with a melee attack while you are raging takes fire damage equal to your Constitution modifier.

Fire's Fury: At 6th level, you can channel your rage into a torrent of searing flames. As an bonus action while raging, you can unleash a wave of fire in a 15-foot cone. Each creature in that area must make a Dexterity saving throw (save DC = 8 + your proficiency bonus + your Constitution modifier), taking 2d6 fire damage on a failed save, or half as much damage on a successful one. The damage increases to 3d6 at 10th level and 4d6 at 14th level. Once you use this feature, you can't use it again until you finish a short or long rest.

Resilience of Flames: Beginning at 10th level, you gain resistance to fire damage, and immunity while raging. Additionally, you gain advantage on saving throws against effects that would cause you to catch on fire or take ongoing fire damage. 

Inferno Avatar: At 14th level, you can transform into a being of pure flame. As a bonus action, while raging, you can assume the form of an Inferno Avatar for 1 minute. During this time, you gain the following benefits:

• Your size increases by one category, and you gain a fly speed equal to your current speed.
• Inferno Aura - Any creature that starts its turn within 10 feet of you takes 1d6 fire damage.
• Inferno Burst - You can use your action to unleash a devastating explosion of flames. Each creature within 30 feet of you must make a Dexterity saving throw (save DC = 8 + your proficiency bonus + your Constitution modifier), taking 5d10 fire damage on a failed save, or half as much damage on a successful one. Once you use this explosion, you can't use it again until you finish a short or long rest.
