Gunsmith

Gunsmith is a Empire military recruitment building in Total War: Warhammer. One who is well-versed in the secrets of shaping ores into gun and artillery barrels. It is a skill set in much demand.

Background
While any blacksmith can hammer out a horse shoe, there are only a few that have been taught at the Gunnery Skull of Nuln to fashion gun and artillery barrels. To keep their prices high, the Gunsmith's Guild jealously guards its secrets, such as how to cool the barrels upright and rifling inside them so shots fire straight!
