I've killed at least fifteen of these guys and still no mask. Though I have friends that got them on the first kill. I'm always hopeful to get a mask, but I never do. It makes me mad. I recently found one on my Hunter when doing the Stillpine Grain quest, and it was by the water. I've only seen them on the paths. Anyway, does anyone have any tips for me to help me get a mask, or will anyone give one to me? :P
