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. 

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.

Drow Weapon Training. You have proficiency with rapiers, shortswords, and hand crossbows.

Faewild Blood. You are naturally attuned to nature. Receive 1 wild shape charge, which can be utilized to change into any creature available to a level 2 Druid. If leveling Druid, this charge adds to your total amount and can be used normally. Optionally, one could instead choose to be proficient in both nature and animal handling.

Destined to Roam. Taking any form of rest with remaining wild shape charges requires a Wisdom saving throw. On a fail, you enter wild shape and “roam” for the duration, only regaining half of the resources normally allocated to that rest. You are conscious and in control of your actions during this time, albeit unable to comfortably rest. If choosing the optional proficiencies, you instead lose those bonuses when you not beneath the sky (DM discretion).
