"Total War Warhammer 3's 4.0 Update Overhauls the Empire"
Total War Warhammer 3 update 4.0 brings significant changes to the Grand Cathay faction, including reworks to the Harmony, Ivory Road, and Wu-Xing Compass systems. The Harmony system now becomes province-based, encouraging specialized settlements favoring Yin or Yang. Loot gained from plundering caravans is limited, and the Wu-Xing Compass affects all regions controlled by Cathayan factions. The Magistrates skill tree is overhauled to improve benefits for leaders who provide buffs and modifiers to the army. These changes are part of the free update accompanying the TWW3 Shadows of Change DLC.
