The intense training of your thoughts have allowed you to bring the strongest of elements of your mind to bear against foreign presences.

When you make an Intelligence, Wisdom, or Charisma saving throw, you may choose to make the saving throw as if it were a different saving throw of your choice from the aforementioned saves. You may substitute this saving throw a number of times equal to your proficiency bonus, and you regain any expended uses when you finish a long rest.
