Darkvision. You can see in dim light within 120 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 blue.
Spider Climb. You have a climbing speed equal to your walking speed. In addition, at 3rd level, you can move up, down, and across vertical surfaces and upside down along ceilings, while leaving your hands free.
Powerful Build. You count as one size larger when determining your carrying capacity and the weight you can push or drag.
Fey Ancestry. You have advantage on saving throws against being charmed, and magic cannot 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.
Languages. You can speak, read, and write Common, Elvish, and Undercommon.
