So Atziri attractiveness confirmed 6/10?

When I was exploring the dialogue of someone that was close to her, he seemed to just go "meh... she wasn't insanely pretty. Just like 6/10. She had some aura in addition to a charm that made people go insane." So what was it that made people go insane over her? Just the fact that she never really turned people down but never explicitly answered the Vaal gooners going crazy for her? An only-vaals profile? Blood magic? What was it?
