Dahlia-Sin'Felle weilding Kozah's Needle
Kozah's Needle was a retractable magic staff that could turn into a triple bar with chains (a dire threshing flail). It was the primary weapon used by Dahlia Sin'felle, one of many users of the staff and seemingly the most proficient.
Kozah's Needle built up an electric charge as it was used, and it could unleash electricity, even channeling it through an opponent's metal weapon. In addition, if Dahlia charged the staff enough, it could burn a hole into an opponent and lay them low with a large blast of lightning.
