You have advantage on saving throws you make to avoid or end the Frightened condition.

As an action, you can exhale destructive energy in a 15-foot cone (or a 5-by-30-foot line for lightning ancestries). Each creature in the area makes a Dexterity saving throw (DC 8 + your Constitution modifier + your proficiency bonus), taking 2d10 damage of the associated type on a failed save, half as much on a success. The damage increases at higher levels. You can use this trait a number of times equal to your proficiency bonus, regaining all expended uses when you finish a Long Rest.

You have resistance to necrotic damage and radiant damage.

At 3rd level, you gain a celestial transformation. Once per Long Rest, as a Bonus Action, you can transform for 1 minute, choosing one of three options: Radiant Soul (a flying speed of 30 feet, and your attacks and spells can deal extra radiant damage equal to your proficiency bonus), Radiant Consumption (you shed dim light and deal radiant damage to nearby creatures and your attacks), or Necrotic Shroud (spectral wings and a frightening aura, with your attacks and spells dealing extra necrotic damage).

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 10 minutes or until you retract the wings (no action required) or have the Incapacitated condition. During that time, you have a Fly Speed equal to 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 Long Rest.

Intelligence, Wisdom, or Charisma is your spellcasting ability for these spells (choose the ability when you select the legacy).
