Battle Hall

The Battle Hall lets you 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, so it's important to let your strongest member lead the rally.

War Tomes can be obtained in chests from monsters, as a possible guild fest reward, or gift packs bought. They can also be purchased in the gem shop. It is recommended that you only buy the 1,000 stacks until your Battle Hall is level 24, at which point you can buy the lower ones for the remainder.

Total number of required War Tomes: 20,000.

War Tome Costs: 1 for 15 gems, 10 for 120 gems, 100 for 1,100 gems and 1,000 for 10,000 gems.

Tip: you need this building maxed for academy level 25 same with the altar and prison so spend gems on these buildings as much as possible so you can unlock t4 faster
