Fallen Aasimar

Fallen aasimar have much more in common with their Tiefling cousins, having roots in fallen celestials. These aasimar rarely bother to differentiate between good and evil, and often follow either the will of their fallen progenitor, or their own chaotic wims. Fallen aasimar despise demons of all kinds and commonly act as spies, informants or emissaries of their diabolic patron. Alternatively, a fallen aasimar can form when a protector aasimar is touched by evil and rejects their divine patron.
Contrary to popular belief, Aasimar are not bound by alignment as heavily as actual angels; Scholars suspect it is because of their half-human nature. Regardless, Aasimar do not gain Fallen attributes as part of falling closer to darkness, but rather have to be directly touched by abyssal or infernal magic, or be born with the Fallen traits from the start.

Darkvision. Thanks to your celestial heritage, you have superior vision in dark and dim conditions. 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.
Celestial Resistance. You have resistance to necrotic damage and radiant damage.
Light Bearer. You know the light cantrip.
Necrotic Shroud. 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 your your turns, you can deal extra necrotic damage to one target when you deal damage 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.

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