Mary Greymalkin

Mary wears Bracers of Defense and a Ring of Protection, and carries a Deck of Several Things

Mary can cause each creature within 10 feet of her to succeed on a DC 12 Wisdom saving throw or become charmed or frightened by her (Mary's choice) until the end of her next turn.

Mary has advantage on saving throws against being charmed, and magic can't put her to sleep.
