Darkvision. Accustomed to twilit forests and the night sky, 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.
Keen Senses. You have proficiency in the Perception skill.
Fey Ancestry. You have advantage on saving throws against being charmed, and magic can't put you to sleep.
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.
Cunning Intuition. When you make a Charisma (Performance) or Dexterity (Stealth) check, you can roll a d4 and add the number rolled to the ability check.
Shape Shadows. You know the minor illusion cantrip. Starting at 3rd level, you can cast the invisibility spell once with this trait, and you regain the ability to cast it when you finish a long rest. Charisma is your spellcasting ability for these spells.
Spells of the Mark. If you have the Spellcasting or the Pact Magic class feature, the spells on the Mark of Shadow Spells table are added to the spell list of your spellcasting class.
