The Battle Hall lets players start or join Rallies. The rally leader's Battle Hall level determines the maximum number of Soldiers in the Rally. Every troop involved in the Rally uses the stats of the rally leader, and not the stats of the player who owns the troops.
Players can also edit their Battalions in the Battle Hall.
War Tomes are required to upgrade the Battle Hall. Total number of required War Tomes: 20,000. The Battle Hall is a permanent building, meaning that once it has been built in a player's Turf, it cannot be demolished.
