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

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 15-foot Cone or a 30-foot Line that is 5 feet wide (your choice each time). Each creature in that area must make a Dexterity saving throw (DC 8 + your Constitution modifier + your Proficiency Bonus). On a failed save, a creature takes 1d10 damage of the type determined by your Draconic Ancestry. On a successful save, a creature takes half as much damage. This damage increases by 1d10 when you reach character levels 5 (2d10), 11 (3d10), and 17 (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.
