About
The War of Emperium is a game feature that allows guilds to fight in order to conquer a Castle to be the headquarters for the guild, and get benefits and special advantages.
Owning a Castle gives your guild several benefits. First off, there is a special Guild Dungeon accessible to everyone in the guild. These dungeons have several strong monsters that in some cases do not spawn in the normal world. Secondly, every night, 4 or more (depending on the economy of the castle) Treasure Chest will appear in the castle giving useful items and equipments.
Mechanics
The character to deal the last hit against the Emperium claims the castle. All characters with a different guild, will be warped out at that point. Only normal attacks can damage the emperium, as all active skills miss. After a castle is claimed, other guilds can immediately re-enter and attempt to break the emperium. The last owner before the emperium disappears at the end of the WoE period holds it until the next period.
The owning guild of a castle has several advantages. Guardians are summoned upon the request of the castle owner's guild leader. They will automatically attack all non-allied characters. Guild members can also click on Flags outside of the castle to be instantly teleported to a specific location inside the castle.
