What powers would a maid of Mind have?

Coming up with great ideas and strategies I could definitely see. Boosting their IQ perhaps to solve advanced problems or to be able to watch Rick and Morty, making facets of themselves to infiltrate a group or simply appear something different than they are… Improving and Healing someone’s psychological state, making their own Choices to overcome fate perhaps?

Also a curious detail- A Maid of Mind, if we take the wordplay of ‘Made of X’, you could have a Maid of Mind technically be like an Imaginary Friend of sorts, a Tulpa, a Brain Projection like Brain Ghost Dirk, someone not physical and in someone’s mind. Literally Made of Mind, a Thoughtform.
