Creature Sense. Princess Hilda is aware of the presence of creatures within 5 miles that has an Intelligence score of 4 or higher. She knows the distance and direction to each creature, as well as each one's Intelligence score, but can't sense anything else about it. A creature protected by a mind blank spell, a non detection spell, or similar magic can't be perceived in this manner

Magic Resistance. Princess Hilda has advantage on saving throws against spells and other magical effects.

Stolen Triforce of Wisdom. When a creature gets with 5 feet of Hilda or starts their turn there, they must make a Wisdom Save DC 10 or take 2d10 necrotic damage.

Psychic Link. Princess Hilda targets one incapacitated creature she can perceive with her Creature Sense trait and establishes a psychic link with that creature. Until the psychic link ends, Princess Hilda can perceive everything the target senses. The target becomes aware that something is linked to its mind once it is no longer incapacitated, and Princess Hilda can terminate the link at any time (no action required). The target can, use an action on its turn to attempt to break the psychic link, doing so with a successful DC 18 Charisma saving throw. On a successful save, the target takes 10 (3d6) psychic damage. The psychic link also ends if the target and Princess Hilda are more than 5 miles apart, with no consequences to the target. Princess Hilda can form psychic links with up to ten creatures at a time.
