Your Charisma score increases by 2, and your Intelligence increases by 1.

Celestial hybrids age as the same rate as humans but live to be about 120 years old.

Celestial hybrids can choose any alignment easily. It's hard to say whether their celestial or infernal parent will influence them more.

Celestial hybrids are about the same size and build as humans. Your size is Medium.

Your base walking speed is 30 feet.

Blessed with a radiant soul, your vision can easily cut through darkness. 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 can’t discern color in darkness, only shades of gray.

You have resistance to necrotic damage and fire damage.

As an action, you can touch a creature and cause it to regain a number of hit points equal to your level. Once you use this trait, you can’t use it again until you finish a long rest.

Starting at 3rd level, you can use your action to unleash the divine energy within yourself, causing your eyes to turn into pools of darkness and two skeletal, ghostly, flightless wings to sprout from your back. The instant you transform, other creatures within 10 feet of you that can see you must each 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.

Your transformation lasts for 1 minute or until you end it as a bonus action. During it, 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 necrotic damage equals your level.

Once you use this trait, you can’t use it again until you finish a long rest.

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

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