Path of the Lesser Dragon.

All Dragonborn have inherited traits from their draconic ancestors. A brave few, who are willing to delve into the more bestial elements of their nature, find they are much closer to their ancestors they first thought. These wild Dragonborn choose to walk what is known as the Path of the Lesser Dragon.

Following your heritage...

Prerequisites: Dragonborn.

At 3rd level, a Dragonborn Barbarian can choose to embark upon the path of their ancestors. This Path will lead you closer to your true draconic nature. It will make a strong warrior stronger, but it will not make them many friends. Most sane mortals fear those who walk the Path of the Lesser Dragon.

Heavy Breathing.

Starting when you choose this path at 3rd level, your heavy breathing collects in a cloud around you. When you rage, you become cloaked in a 5 foot cloud of draconic breath until the rage ends. At the end of each of your turns for that duration, each creature within 5 feet of you takes damage equal to 1d4 + half your barbarian level. The damage is the same type as your breath weapon.

Scaly Hide.

When you choose this path at 3rd level, your scales become tougher and react to your emotional state. Rage strengthens your draconic resiliance far beyond its normal capabilities. Your scales bristle and stand on edge, helping you shrug off even more of what the world throws at you. While raging, you have resistance to all damage except psychic, radiant, and necrotic damage, provided you are not wearing any armor.

Furious Torrent.

Beginning at 6th level, if you use your Draconic breath while raging, the range of the breath weapon is doubled and you add 1d6 + your Rage damage to the total damage dice for the attack.

Terrifying Roar.

Starting at 10th level, you can summon the fury of the true dragons by letting out a terrifying roar. Once per long rest, when you start to rage, you can let out a bestial war cry that shakes your enemies to their core. All hostile creatures within 60 feet that can hear you must make a wisdom save, and on a failed save they become frightened of you for one minute(on a successful save nothing happens). The DC for this save is determined by the following calculation: 10+ your Strength Modifier + your Constitution modifier.

True Draconic Resilience.

Starting at 14th level, when you are raging, you are immune to the type of damage assoicated with your Draconic resilience, and any ally within 5 feet of you gains resistance to that type of damage.
