Way of Many Minds.

The way of Many Minds focuses on unlocking latent parts of our consciousness, excavating the power to turn thoughts and willpower into material forces and illusions. The Monasteries of the Way of Many Minds focus on mysticism and striving into one's own mind, as well as others'. A monastery of the Way of Many Minds might only induct those they found to have profound psionic potential, they might try to "uplift" those without any. Some monasteries only accept those that seek them out, while others prefer to find their potential members first. 

Egregor

You have learned the technique of turning imagination and force of will into a psionic force.

As an action, you can cast the following spells by spending 3 Ki points: Shadow Blade, Phantasmal Force, Mirror Image. Furthermore, you learn the Minor Illusion cantrip. When cast this way, these spells are cast without material components. These spells are always cast at second level, these spells use your Ki save DC, Wisdom is your spellcasting ability for these spells.

Physical Egregor

Your focus, imagination, and willpower have grown so strong that what had previously been illusions now have a physical form.

Your illusions from your Egregor spells above 1st level now have a physical form, taking the shape of the created illusion. These physical forms have a strength and dexterity score equal to your wisdom modifier (minimum of 1) and a number of hit points equal to your monk level. The physical forms of the illusions last until the spell cast to make it ends.

The Many Minds

You can see through the senses of all of your Egregor spells' illusions (if they have senses).

Additionally, if you're concentrating on an illusion spell above first level and your hit points drop to zero, make a DC 15 Wisdom saving throw, on a failure, proceed as normal when hit points drop to 0. If the saving throw is successful, your body disappears and your illusion morphs into a perfect replica of you, with your own mind in it. Mechanically, you teleport to the space of your illusion and concentration on the spell is ended. Your hit points equal that of the illusion's physical form before dropping to 0 hit points.

Awakened Egregor

When one of your Egregors drops to 0 hit points, you can choose to spend your reaction siphoning your being into it. Spend any number of your hit dice that you choose and roll them, add your wisdom modifier the sum of the roll, this total number becomes the Egregor's current hit points.

When you do this, roll a Wisdom saving throw against your Ki save DC, upon a success, you keep concentration on the Egregor. Upon a failure, your concentration on the Egregor ends, but it still remains. The newly rejuvenated Egregor gains a will of its own and will act in self-preservation, it has all of your memories and the same Intelligence, Wisdom, and Charisma scores as you do, but lacks a sense of empathy or humanity.
