Your lineage stems from a dragon progenitor. Choose the kind of dragon from the Draconic Ancestors table. Your choice affects your Breath Weapon and Damage Resistance traits as well as your appearance.

 Choose the second kind of dragon from the Draconic Ancestors table. You cannot pick a Dragon that has the same Damage Type.

When you take the bonus action on your turn, you can replace your bonus action with an exhalation of weaker magical energy. You can use your second Breath Weapon once per Short Rest.

When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy in either a 10-foot Cone or a 25-foot Line that is 5 feet wide (choose the shape each time). Each creature in that area must make a Dexterity saving throw (DC 8 plus your Constitution modifier and Proficiency Bonus). On a failed save, a creature takes 1d8 damage of the type determined by your Draconic Ancestry trait. On a successful save, a creature takes half as much damage. This damage increases by 1d8 when you reach character levels 5 (2d8), 11 (3d8), and 17 (4d8).

You can use this Breath Weapon a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.

You have Resistance to the damage type determined by your Draconic Ancestry trait.

You have more resistances as determined by your secondary Draconic Ancestry trait.

You have Darkvision with a range of 50 feet.

When you reach character level 5, you can channel draconic magic to give yourself temporary flight. As a Bonus Action, you sprout spectral wings on your back that last for 30 minutes or until you retract the wings (no action required) or have the Incapacitated condition. During that time, you have a Fly Speed twice your Speed. Your wings appear to be made of the same energy as your Breath Weapon. Once you use this trait, you can’t use it again until you finish a Short Rest.

When you take an Action on your turn, you can, once per Long Rest, replace your action with an exhalation of dual-powered magical energy in either a 20-foot Cone or a 50-foot Line that is 10 feet wide (choose the shape each time). Each creature in that area must make a Dexterity saving throw (DC 10 plus your Constitution modifier and Proficiency Bonus). On a failed save, a creature takes 2d6 damage of each type determined by your Draconic Ancestry traits. On a successful save, a creature takes half as much damage. This damage increases by 1d6 when you reach character levels 13 (3d6), 16 (4d6), and 19 (5d6). Both damage types are rolled separately.
