I wanna assume that's where Soul Resonance would come in, depending on the Semblance of course. If it was some sort of power booster type deal, Resonance fits best. If it were along the lines of creating glyphs, that'd probably be more of a field for witches only, but might be plausible simply through resonance as well... that is a good question.
