I guess the proper way to tier 3 or advancing to another tier of magic is slowly learning magics and theory of that tier one step at a time but desir method is cramming all of his knowledge and observation of what makes a tier 3 magician into a single theory without learning tier 3 magic and theory then, making a training method that forces a person to learn it by intuition... it's like being able to do it but don't know and can't explain how you do it....
