Building - Hall of War

The Hall of War allows you to launch and join rallies with your allies. Upgrade it to increase the number of troops that can march in the rally. Rallies enable you to amass a much larger army than if you attacked by yourself. The size of the rally and the number of participants can also be increased through donations to Alliance Tech. Upgrading your Hall of War requires Books of War which will be used automatically whenever you upgrade.
