Elves do not sleep. Instead, they meditate deeply, remaining semi-conscious, for 4 hours a day. The Common word for this meditation is “trance.”
While meditating, you dream after a fashion; such dreams are actually mental exercises that have become reflexive after years of practice. After resting in this way, you gain the same benefit a human would from 8 hours of sleep.
The below is for Shadar-kai ONLY:
Whenever you finish this trance, you can gain two proficiencies that you don’t have, each one with a weapon or a tool of your choice selected from the Player’s Handbook. You mystically acquire these proficiencies by drawing them from shared elven memory, and you retain them until you finish your next long rest.
