Like barbarians with spirit totems, those that follow the path of the dragonwyld tap into the primal spirit that gave birth to dragons. Dragonwyld barbarians can shrug off elemental damage, summon a breath weapon, project an aura of fear, and even fly for short distances.
Path of the Dragonwyld (Barbarian)
At 3rd level, when you choose this path, select a dragon type from the list of dragon types available to dragonborn. You gain advantage on saving throws against damage of the type associated with your dragon.
At 6th level, you gain a breath weapon similar to that of a dragonborn. While you are raging, you may take an action to make a breath weapon attack of the same area and elemental type of your chosen dragon type. Once you use this ability, you may not use it again until you've take a long rest.
Beginning at 10th level, you can use your action to frighten someone with your menacing presence. When you do so, choose one creature that you can see within 20 feet of you. If the creature can see or hear you, it must succeed on a Wisdom saving throw (DC equal to 8+your proficiency bonus + your Charisma modifier) or be frightened of you until the end of your next turn. On subsequent turns, you can use your action to extend the duration of this effect on the frightened creature until the end of your next turn. This effect ends if the creature ends its turn either out of line of sight, or more than 60 feet away from you.
If the creature succeeds on this saving throw, you can't use this feature on that creature again for 24 hours.
Blessing of Flight
While raging, you have a fly speed equal to your current walking speed. This benefit works only in short bursts; you fall if you end your turn in the air and nothing else is holding you aloft.
