Your creature type is Dragon.

Your Wisdom score increases by 2 and another ability score of your choice increases by 2.

Dragonborn mature at the same rate as humans, but they can live to be a thousand years old if they take care of themselves. Most make it to around 500, adventurers to only about 300 as the adventuring life takes quite the toll.

The average dragonborn towers at 6 and a half feet. But they can stand anywhere from 7 feet tall to just 3 and a half tall, though it is rare to find a dragonborn that short. You choose whether you are Medium or Small.

Your base walking speed is 30 feet.

Choose acid, cold, fire, force, necrotic, lightning, poison, psychic, radiant, or thunder. Your breath weapon deals damage of this element and you have resistance to the chosen element.

Rebirth Cycle

Over the course of a fortnight, a dragonborn's scales start to thin and become pale and skin-like as new scales grow underneath. On the fourteenth night of this cycle, during a long rest, your old scales shed and reveal new scales underneath. If you spend the two downtime hours of the long rest before you sleep meditating on your rebirth, you can change your Draconic Element to different one listed above. The Rebirth Cycle then starts over.

When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy in a 15-foot cone or a 30-foot line that is 5 feet wide. Each creature in that area must make a Dexterity saving throw (DC = 8 + your Constitution modifier + your proficiency bonus). On a failed save, the creature takes 1d10 damage of the type of your Draconic Element. On a successful save, it takes half as much damage. This damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).

You can use your Breath Weapon a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Secondary Effect

You can add a secondary effect to your Breath Weapon. When you use your breath weapon, choose one of the following effects.

Enervating Breath. Each creature in the area of effect must succeed on a Constitution saving throw against your breath weapon's DC or become incapacitated until the start of your next turn.

Repulsion Breath. Each creature in the area of effect must succeed on a Strength saving throw against your breath weapon's DC or be pushed 20 feet away from you and be knocked prone.

Once you add a secondary effect to your Breath Weapon, you can’t do so again until you finish a long rest.

Starting at 5th level, you can use a bonus action to manifest spectral wings on your body. These wings last for 1 minute. For the duration, you gain a flying speed equal to your walking speed and can hover. Once you use this trait, you can’t do so again until you finish a long rest.

You have a large, powerful tail you can use to make unarmed attacks. If you hit with it, you deal bludgeoning damage equal to 1d10 + your Strength modifier. In addition, the target must succeed on a Dexterity saving throw (DC equal to 8 + your proficiency bonus + your Strength modifier) or be knocked prone.

You can speak, read, and write Common, Draconic, Auran, and one other language of your choice.
