The exceptions to this are your basic skeleton warriors and skeleton spearmen, which are not only free, but uncapped, meaning you can run 20-stack armies right from the start of the game – recruitment time is your only limitation. Instead, their armies and their units have a simple cap, which you must raise through research and building, possibly reflecting the process of awakening from centuries of death and working to restore their former glory. The Tomb Kings are up there with the Skaven for the weirdest faction in Total War as a series to date, for one game-changing reason: they pay no gold to either recruit or maintain their units.
