Blessed with a necrotic 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 radiant damage.

As an action, you can touch a creature and cause it to gain a number of hit points equal to your level. Dark Aasimar often use this trait to keep their enemies on the brink of death or save their allies for their own personal gain. 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.

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 ghostly 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.
