Draconic Ancestry

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 Prismatic Nature 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.

You have resistance to the damage type associated with your draconic ancestry.

You have the ability dig deep into your draconic nature, allowing you to turn into a more Draconic form, fit with wings, horns and a tail. As a bonus action you can switch forms. Soar and Breath Weapon place you in Draconic Form upon use, and using a bonus action to revert to humanoid form ends Soar early. 

Starting at 5th level, you can use a bonus action to transform into a winged draconic form. This lasts 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.
