Path of the Dragon

Barbarians who walk the Path of the Dragon draw on the destructive potential of dragons when they rage.

Such a barbarian might have a dragon ancestor or have been exposed to a dragons influence for a prolonged period.

Dragon's Might

3rd-level Path of the Dragon feature

When you enter your rage, you can channel a small part of the draconic influence within you. When you rage, your AC increases by 1 as scales form and harden over your body. While raging, each of your hands transforms into a claw, which you can use as a weapon if it’s empty. It deals 1d6 slashing damage on a hit. Once on each of your turns when you attack with a claw using the Attack action, you can make one additional claw attack as part of the same action.

Dragon's Spirit

6th-level Path of the Dragon feature

Starting at 6th level, the Draconic Influence within you grants you a measure of protection. If you fail a saving throw while you’re raging, you can reroll it, and you must use the new roll. You can use this ability only once per rage.
The claws of your Dragon's Might feature now count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Dragon's Mass

10th-level Path of the Dragon feature

When you rage, your body swells as your draconic nature seeks to break through. Your size increases to Large, and your melee attacks deal an extra 1d4 damage.

Your scales harden further providing an additional 1 AC, for a total bonus of 2 to AC.

Dragon's Freedom

14th-level Path of the Dragon feature

Wings grow from your back, granting you a flying speed of 30ft. When you rage these wings expand and increase your flying speed to 50ft.
