The Ren Concussive War Club is a sinister, hodgepodge club featuring a kinetite charged striking head with concussion vector vanes. Studs line the entire handle of the club for added grip. It had the ability to build up a concussion charge in a kinetite generator that could be released in a sudden shockwave upon striking something, with a charge level indicator on the upper portion of the weapon. One such weapon was used by Ushar, one of the Knights of Ren.
