Sapient targets will have to best the user of either in order to not be torn apart or altered, and the powers are heavily reliant on force-of-mind, making it hard for the user to do anything else while messing with matter. With enough training (we're talking at least three decades worth of study) they will be able to actively participate in combat and use matter/anti-matter. The limitations on sapient beings may only be overcome by gods.
