You gain Darkvision out to 60ft

You have gained the intuitive nature to pick up skills and understand things quickly like a kobold allowing you proficiency in one skill

Your Draconic Heritage gifts you with an iron will that withstands even the most fearsome of foes. You have Advantage against the Frightened Condition

You can increase one score by 2, and another score by 1.

Drakebolds reach adulthood at age 8 and can live to about 100 which is longer than most dragonborn and even some kobolds who make it to that age.

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. 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 associated with your Metallic Ancestry. 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.

Drakebolds range in size from slightly larger kobolds to the size of some dwarves.

Your base walking speed is 30 feet.

You gain resistance to the damage type associated with your draconic heritage

You can speak, read, and write Common and Draconic. Draconic is thought to be one of the oldest languages and is often used in the study of magic. The language sounds harsh to most other creatures and includes numerous hard consonants and sibilants.
