The Blinding Staff is a weapon used by Lloyd Garmadon. It is a black and gray staff with a yellow disc on one end. The latter emits light that can illuminate areas or blind opponents, and the staff's light output can be adjusted for short and long-range use. It is found exclusively in the Lloyd Garmadon spinner set.
Even the darkest lord in training sometimes needs a light. In Lloyd's case, this Blinding Staff is perfect for, well, blinding his enemies. Adjustable for close or long range use.
