Part of the problem with trying to imitate someone else, regardless of whether you look, sound, smell and feel like them, is that you can still give yourself away by not acting like them. Shape Shift Persona lets you change your personality so even slight, subtle mannerisms can be imitated. There are dangers to Shape Shifting Persona. If you attempt to Shape Shift into the personality of a particularly powerful mind, you run the risk of it overwhelming you. In essence, you actually become that person, and may totally lose control over your character. Usually this ends with sleep or unconsciousness, when your own natural Persona will come back into existence.
