Staff of Erasing

The Staffs of Erasing were weapons used by Vahki Vorzakh. They were to temporarily eliminate a target's higher mental functions, leaving only their motor functions intact.

The Staffs of Erasing went out of use after the Great Cataclysm, when all the Vahki were destroyed.

Trivia

 * In BIONICLE 2: Legends of Metru Nui, all Vahki seen held Staffs of Erasing; however, the Vahki seen were exclusively Zadakh and Rorzakh (as opposed to the Vorzakh who held these Staffs in set form), and the Vahki held the Staffs of Erasing backwards compared to how they were held in the set.
