At 3rd level, when you take damage from an area attack, each ally you can see who was also a target of that attack gains a +1 bonus to attack rolls against the creature that attacked you until the end of your next turn. If the attacker is a dragon, it is advantage.

At 6th level, when an ally you can see uses their action to make an attack and misses, the ally gains temporary hit points equal to your level and can make a saving throw. If the ally's attack missed a dragon, the ally regains hit points equal to your level instead of gaining temporary hit points.

At 14th level, on a successful hit, you deal damage as normal, and an ally adjacent to the target can make a melee attack against the target as a reaction. You then move 5ft and make a bonus attack. If the target is a dragon, you can instead move 15ft. On a successful hit, you deal damage as normal, and an ally adjacent to the target can shift 5ft and make another attack. If the target is a dragon, the ally can instead move 15ft.

You and an ally skim along the enemy's flank, stabbing as you go.

At 14th level, when an ally within 25ft attacks an enemy, the attack scores a critical on a natural roll of 19 or 20. If the target is a dragon, it scores a critical on a natural roll of 18, 19, or 20.

With a shout, you direct your ally's blow where it will inflict the most harm.

If the target is a dragon, it takes a –1 penalty to the triggering attack for each such melee attack that hits.

At 20th level, once per short rest, when using your action to attack, on a successful hit, you multiply your damage by 3. Until you end your turn in a square not adjacent to the target, when the target makes an area attack, you and each ally adjacent to it can make a bonus melee attack against the target as a reaction.

You and your allies are ready to strike at the first sign of the dragon's breath.

Flamebrow Commander

A dragon driven to wrath is a terrifying foe. It stops at nothing to quench its fury in the blood of those who wronged it. Only the desire to protect its young can drive a dragon to even greater heights of recklessness. A dragonborn warrior is little different, and a dragonborn officer displays parental loyalty to those alongside whom he fights. Such is the dragonborn warrior ideal.

An exemplar of this standard was Dhuryan Flamebrow, an audacious but beloved dragonborn mercenary from the fringes of the empire of Arkhosia. Dhuryan was noble born, but upon him fell the consequences of his father's dark deeds. Without title or property in the empire, and living under the shadow of family history, he made his way as a soldier and leader. He made a habit of leading from the front with a brashness born of being indifferent to death. Glory and the erasing of the past was his overriding aim, yet he was unwilling to sacrifice his fellow fighters for his own gain.

Dhuryan succeeded in reshaping the armies of a border province known for its barbarism and monster problems. Eventually, that province and its dragon lord became the most prominent in Arkhosia, although only Dhuryan's name is widely remembered to this day. At long last, Dhuryan had cleansed his family name. He rose then to prominence as a military advisor and became a general in the wars that eventually destroyed Arkhosia.

During this time, he penned the military manifesto titled Flamebrow, in honor of his clan. Myths from many cultures say that Dhuryan fought in numerous wars in this world and beyond, and that he fell but returned to life more than once. Tales say that he stands now beyond the touch of time, alongside other legendary generals, awaiting the world's need.

Flamebrow still exists, copied into many languages. It is a treatise for the commander who wishes to defeat enemies head-on. Although it speaks of deceptive planning and long-term strategies, it also talks of brutal efficiency and courageous leadership when battle is joined.

Whether through influence, reading and practice, or direct training, your path has been influenced by Flamebrow. Boldness of action fails to fully describe your methods. You act decisively, willing to lay your own survival on the line to get the job done and protect your allies.

Flamebrow Revival At 3rd level, when you are dying, you add your Charisma modifier to any hit points you regain, and you gain a bonus to death saving throws equal to your Charisma modifier.

Relentless Action At 3rd level, when you spend an action to attack, you can use your Bravura Presence class feature as if you were your own ally.

Roaring Recovery At 6th level, each time you regain hit points when you are below half health, you gain advantage to attack rolls until the end of your next turn.

Flamebrow Assault On your cue, your comrade attacks. You build on his or her success to land your own strike. At 14th level, before attacking, one ally below half health within 25ft of you can make an attack using a reaction, with a bonus to the attack roll equal to your Charisma modifier. If that attack hits, you gain advantage to your attack roll; if it misses, you take disadvantage to your attack roll. On your successful hit, you multiply your damage by 3.

Rallying Lure Paying more attention to the welfare of your flagging friends than to your own safety, you shout heartening words. At 14th level, you take a martial stance. Until the stance ends, you grant advantage to all enemies. At the start of your turn, each ally below half health within 25ft of you regains hit points equal to your Charisma modifier. If no allies below half health are within 25ft of you at the start of your turn, the stance ends.
