The main buildings: city hall, warehouse, shop and blacksmith are all given shield generators which protect the buildings from the Metor Strike attacks of the enemy grand magic generator. It's your duty and that of your guilds to defend your own shields and attack the shields of the enemy.

Once a Crusade begins, an Grand Magic Generator is automatically spawned outside the City Hall of either town. The purpose of a Crusade is to lead your city by building up base in the middle lands around the Mana Stones. There are 3 modes that you can chose from during the crusade Commander, Constructor and Soldier.

• Commanders are Guild Masters by default, Guild Masters can only be Commanders. They have the ability to spawn War units based on the amount of points that they have. You can collect points by killing the enemy players, enemy war units and enemy base structures. Also they set teleportation points in middleland and the construction zone for they guild.
• Constructors are the only ones who are able to build a limited amount of structures for your guild You must also be a part of a guild in order to be given the option of Commander. A combination of defensive, attacking and practical structures are required to create a successful base.
• Soldiers are given bonus attack power.

You can change your status from Constructor to Soldier in the City Hall as many times as you like during the Crusade. If you have no guild, you are only able to become a Soldier.
