Accustomed to twilit forests and the night sky, you have superior vision in dark and dim conditions. 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.

You have advantage on saving throws against being charmed, and magic can't put you to sleep.

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.

You have proficiency with the longsword, shortsword, shortbow, and longbow.

You can attempt to hide even when you are only lightly obscured by foliage, heavy rain, falling snow, mist, and other natural phenomena.

You gain a +2 to your initiative rolls.

Whenever you roll radiant damage with a cantrip, you can use Celestial lights to deal maximum damage, instead of rolling. You can do this a number of times equal to your wisdom modifier. You regain all uses of Celestial lights after a long rest.

Starting at 2nd level, you can use your Channel Divinity to harness the power of the stars from within your spells, dealing damage. As an action, while you are concentrating on the spell Arcane Eye, Dancing Lights, Faerie Fire, or Moonbeam, you may present your holy symbol and make your spell burst with starlight. Each hostile creature within 15 ft of the spell's center must make a Constitution save. A creature takes radiant damage equal to 4d6 + your cleric level on a failed saving throw, and half as much damage on a successful one. If there is more than one spell origin, use all of them. Starburst cannot overlap onto its self.

As an action, you present your holy symbol and speak a prayer censuring the undead. Each undead that can see or hear you within 30 feet of you must make a Wisdom saving throw. If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage.

A turned creature must spend its turns trying to move as far away from you as it can, and it can't willingly move to a space within 30 feet of you. It also can't take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there's nowhere to move, the creature can use the Dodge action.
