You are exceptionally cunning in mentally distinguishing the natural from the supernatural, and you gain the following benefits:

Gain proficiency in Intelligence saving throws, or in another saving throw if you're already proficient.
You can't be charmed, and spells can't put you to sleep.
You can Search as a bonus action, but only to locate something you suspect to be invisible, to determine the true nature of a potential illusion, or to determine if something is magically transformed.
You have advantage on any Intelligence, Wisdom, or Charisma check imposed on you by any spell, including any Search action taken in regards to a spell.
