Zenji needles represented a unique type of throwing weapon, specifically crafted for the use of the Mistryl Shadow Guards. These needles measured ten centimeters in length, featuring a lacquered finish and an ornamental jewel affixed to one extremity. This jewel served the dual purpose of enhancing both the weight and equilibrium of the weapon. Typically, zenji needles were utilized as decorative accessories within the hair of their wielders. The Mistryl Shadow Guards demonstrated exceptional proficiency in the deployment of these weapons, achieving remarkable precision in their throws; zenji needles possessed the capacity to fracture armor upon impact when propelled with adequate force.
