Heightened Senses

You have advantage on Perception checks that rely on sight or hearing. You can see through lightly obscured areas normally and areas of dim light as if it were bright light.

Magic Ancestry

You have advantage on saves against being charmed, and magic can’t put you to sleep.

Trance

Elves don’t need to sleep. Instead, they enter a meditative trance state, remaining semiconscious for 4 hours a day. You choose whether or not you can dream while meditating. After resting in this way, you gain the same benefit that other creatures do from 8 hours of sleep.
