Dragonborn

Draconic Ancestry. Choose a dragon ancestor. It determines the damage type used by your Breath Weapon and Damage Resistance, and it influences your appearance.

Breath Weapon. When you take the Attack action, you can replace one attack with magical breath in a 15-foot cone or a 30-foot line (5 feet wide). Targets make a Dexterity save (DC 8 + CON mod + Proficiency Bonus), taking 1d10 damage on a failed save or half on a success. Damage scales to 2d10 at level 5, 3d10 at 11, and 4d10 at 17. Uses equal to your Proficiency Bonus, regained on a Long Rest.

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

Darkvision. You have Darkvision out to 60 feet.

Draconic Flight. Starting at level 5, as a Bonus Action you can manifest spectral wings for 10 minutes, gaining a Fly Speed equal to your Speed. Ends early if you retract the wings or become Incapacitated. Recharges on a Long Rest.
