Your elf character has the following hereditary traits.
Age. Although elves reach physical maturity around age 20, mental and emotional faculties reach full maturity around the age of 100. Elves can live to be 750 years old.
Size. Your size is Medium. Elves range from under 5 feet to over 6 feet tall and tend toward slender builds, averaging around 110 pounds.
Speed. Your base walking speed is 30 feet.
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.
