Incorporeal Movement. Anya can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if she ends her turn inside an object. She does not take this damage when within Shuri's shadow, and moves as it does with no effort.
Psychic Mind. Anya can read the minds of any being within 100ft without effort. If she chooses to concentrate for a minute she makes an Int check, and adds Int Check - 10 * 100 to that range. This also grants her immunity to any attempt to meddle with her head, this includes being Charmed or Frightened, and Psychic damage.
Psychic Sonar. Because of her innate psychic ability, Anya knows the location of every creature within 100ft, however the more creatures there are the less precise this is.
Psycho Cut. Like the Pokémon move, Anya slashes the air and creates a magical purple slash that hurls towards its target. Range 60ft 1d12 Psychic damage or Range 5ft 2d12 Psychic damage. This attack can benefit from sneak attack that deals an extra 4d6 slashing damage.
Psychic Scream. Anya focuses on a single target for up to a minute using concentration and forces any checks to be made to be done so at disadvantage.
GTFO. Anya can spend her bonus action to enter or leave the ethereal plane.
Can take a reaction to shield an allies mind, adding a d6 to their Int or Wis saves.
