Well it was a basic concept from the outset. As for the semblance it coats her bullets much you would do with aura but unlike basic aura it creates a piercing round by forming around the shell itself while the explosive one just coats the shell and explodes inside the target. However I do like your idea. First shot could mark the target by generating the hole while the second one targets the same hole and enters it and explodes.<br/><br/>What I was kind of thinking for her was that she was a survivor of one of those villages they talk about that disappeared overnight. What leads to her attitude being what it is would be this traumatic experience of basically watching her whole family slaughtered before her eyes by Grimm and the only thing that saved her was a lone wandering hunter who wasn't able to do much to save the village but he was able to save her. Since it was also established that Vacuo is one of the more least settled of the kingdoms I thought it made a perfect place for this kind of character. Does this help a bit?
