You have resistance to necrotic damage and radiant damage.

You can see in dim light within 60 feet of you as if it were bright light and in darkness as if it were dim light. You discern colors in that darkness only as shades of gray.

As an action, you can touch a creature and roll a number of d4s equal to your proficiency bonus. The creature regains a number of hit points equal to the total rolled. Once you use this trait, you can’t use it again until you finish a long rest.

You know the light cantrip. Charisma is your spellcasting ability for it.

When you reach 3rd level, choose one of the revelation options below. Thereafter, you can use a bonus action to unleash the celestial energy within yourself, gaining the benefits of that revelation. Your transformation lasts for 1 minute or until you end it as a bonus action. Once you transform using your revelation below, you can’t use it again until you finish a long rest:

Necrotic Shroud. Your eyes briefly become pools of darkness, and ghostly, flightless wings sprout from your back temporarily. Creatures other than your allies within 10 feet of you that can see you must succeed on a Charisma saving throw (DC 8 + your proficiency bonus + your Charisma modifier) or become frightened of you until the end of your next turn. Until the transformation ends, once on each of your turns, you can deal extra necrotic damage to one target when you deal damage to it with an attack or a spell. The extra damage equals your proficiency bonus.

Radiant Consumption. Searing light temporarily radiates from your eyes and mouth. For the duration, you shed bright light in a 10-foot radius and dim light for an additional 10 feet, and at the end of each of your turns, each creature within 10 feet of you takes radiant damage equal to your proficiency bonus. Until the transformation ends, once on each of your turns, you can deal extra radiant damage to one target when you deal damage to it with an attack or a spell. The extra damage equals your proficiency bonus.

Radiant Soul. Two luminous, spectral wings sprout from your back temporarily. Until the transformation ends, you have a flying speed equal to your walking speed, and once on each of your turns, you can deal extra radiant damage to one target when you deal damage to it with an attack or a spell. The extra damage equals your proficiency bonus.

You can use your action to exhale destructive energy. Your draconic ancestry determines the size, shape, and damage type of the exhalation. When you use your breath weapon, each creature in the area of the exhalation must make a saving throw, the type of which is determined by your draconic ancestry. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. A creature takes 2d6 damage on a failed save, and half as much damage on a successful one. The damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. After you use your breath weapon, you can’t use it again until you complete a short or long rest.

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

You can speak, read, and write Common, Celestial, 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.

Draconic Seraphim Children mature at the same rate as humans, but they can live up to 160 years
