The jezzails employed by the Skaven use a distinct "warplock" technology perfected by the Warlock Engineers. The warplock jezzail operates on a principle similar to that of a wheel-lock musket, but small amounts of Warpstone have been worked into both the weapon's metal components and its ammunition. This provides for added barrel strength, allowing a larger measure of Warpstone-fortified powder to be loaded into the weapon.
