Technically, all she needs to do is gain a firm resolve in order to injure and defeat opponents. As proven in the Fullbringer arc, she's steeled up considerably over the timeskip, having developed a "sadistic" attack like Shiten Kōshun that attacks while defending, so I can see her finally defeating a Sternritter or somesuch in this arc - after all, Kōten Zanshun can basically kill anyone if Orihime has enough resolve.
