While nothing created by the Ash Cult could be considered mass-produced, this +1 striking ruinous hand cannon is by far their most popular design. The sleek body and intricate carving work make it a favorite accessory of certain aristocrats. The carving isn't merely decorative, however. Rather than a traditional maker's mark, Ornmarr etches excerpts of unreadable text onto each creation, hoping that one day his weapons will sing to another as the silver crystal once sang to him.
