Sword Sisters are elite female mercenary cavalry. Despite slowly evolving from initially vulnerable and unarmed women, Sword Sisters are extremely powerful fighters on par with Mercenary Cavalry. Sword Sisters demand significantly lower wages compared to their male counterparts, therefore procuring them can be very worthwhile from a financial point of view. The most reliable way to acquire Sword Sisters is by upgrading Refugees and Peasant Women. These units are difficult to acquire as they can only be hired from a defeated party's prisoners or captured by attacking traveling villagers, so for most players, this troop line will be very rare.
