Shadar-Kai

As a bonus action, you can magically teleport up to 30 feet to an unoccupied space you can see. You can use this trait a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

At 3rd level, you also gain resistance to all damage when you teleport using this trait. The resistance lasts until the start of your next turn. During that time, you appear ghostly and translucent.

Thanks to your heritage, 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.

You have proficiency in the Perception skill.

You have resistance to necrotic damage.

You don’t need to sleep, and magic can’t put you to sleep. You can finish a long rest in 4 hours if you spend those hours in a trancelike meditation, during which you retain consciousness.

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.
