• You can use your breath weapon a total amount equal to your constitution modifier.
• Your breath weapon now has a recharge of 5-6. After using your breath weapon once you must roll 1d6 at the beginning of your next turn on a 5 or 6 your breath weapon recharges and is able to be used again.
• Breath weapon’s bonus damage: You add 1d6 damage when using your breath weapon / or 2d6 damage to Draconic Wrath. The bonus damage to Draconic Wrath becomes 3d6 at 19th level.

• The range or your breath weapon is unchanged and you regain all expended uses after a long rest.

Ancestral power

• Draconic Fury: Starting when you choose this path at 6th level, you can channel your draconic power into your weapon strikes. While you’re raging, the first creature you hit on each of your turns with a weapon attack takes extra damage equal to 1d8 + half your barbarian level. The extra damage is the same energy type as your breath weapon 
• Draconic Movement: at 6th level, you gain an additional form of movement depending on your Dragonborn type. The movement speed will be equal your normal speed ( those who gain a swimming speed also gain water breathing) Black-swim, Blue-climb, Brass-burrow, Bronze-swim, Copper-climb, Gold-swim, Green-swim, Red-climb, Silver-burrow, Wite-burrow 

Draconic Presence

Beginning at 10th level, you can use your action (or a bonus action while in rage) to frighten someone with your Draconic presence. When you do so. choose one creature that you can see within 30 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 or Strength 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 out of the line of sight or more than 60 feet away from you.(If the creature succeeds on its saving throw, you can't use this feature on that creature again for 24 hours.)

Draconic Immunity and Flight

• Draconic Immunity: Starting at level 14, you gain immunity to the type of damage you deal with your breath attack. 
• Draconic Flight: At level 14 when you enter a rage, massive dragon wings sprout from your back. If you are not wearing heavy armor, you gain a flying speed equal to your movement speed.
