Homebrew Cambion Elf Species Details

Cursed with 50% of infernal ancestry, Cambion Elves go beyond just a Tiefling.  They retain elf characteristics so that they are even deadlier for the devils that created them in the first place.  This isn't the result of a curse.  This is the result of a devil and elf having a child for whatever reason.  These tend to be when an archdevil wants a child that has more of their genetics in the child due to one of the parents being an actual archdevil.  It is speculated that they are created from a devil wanting a living weapon with elf fey ancestry to mix with their own infernal legacy.  They are rare but from what few specimens have been observed, these traits have been found.  Cambion elves mostly resemble elves with a few key differences.  Cambion elves don't have normal teeth in favor of devish fangs, similar to tieflings.  They also have horn nubs in differing places on their head.  They seem to exhibit traits from their specific devilish parent.  One was observed to have draconic eyes and blue hair, abnormal for an elf.  Another was discovered with flaming eyes and ash colored skin.  They appear to have a will outside that of their parent so reason for fear is low if even existent.

Languages

You know common, elvish, and infernal.

Trance

Elves don’t need to sleep. Instead, they meditate deeply, remaining semiconscious, for 4 hours a day. (The Common word for such meditation is “trance.”) While meditating, you can dream after a fashion; such dreams are actually mental exercises that have become reflexive through years of practice. After resting in this way, you gain the same benefit that a human does from 8 hours of sleep.

Darkvision

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.

Fey Ancestry

You have advantage on saving throws against being charmed, and magic can't put you to sleep.

Legacy of Stygia

You know the ray of frost cantrip.  At 3rd level, you can cast armor of Agathys once per long rest as a 2nd-level spell.  At 5th level, you can cast darkness once per long rest.  Charisma is your spellcasting ability for these spells.
