When the Heroes Awaken update goes live in ArcheAge, new guild functionality will added that will make recruiting and advertising simpler and will add guild levels. Each level will offer members passive bonuses and items to purchase through the guild prestige shop.
Most interestingly, guilds will be able to battle one another in the Guild Dominion system. Two guilds of level 3 or above can declare Dominion on each other 3 times per day. Each Dominion lasts for one hour. During this time guards will not interfere and battles can take place even in peace zones.
During the Dominion, no bloodstains are generated and your Hostile Faction Kills will increase, but you will not be able to earn Honor Points through kills. Guilds will also not be able to accept new members, guild members won’t be able to leave, and kills from members added to participating guilds just prior to the war will not count. These newly added players will also be attacked by guards in safe zones if they start a fight, as normal.
