In the update on August 24, a new RB level was added. Also added new maximum levels of buildings in the Personal Fort.
Guild Raid Bosses.
Added a new level of complexity Guild Bosses, from which you can knock out mythical jewelry. The number of visits has not been reset, so those guilds that were scored in their time on the guild RB, now can safely pass all the accumulated.
Added new maximum levels to some buildings in the personal Fort.
They added new costumes. Which give more experience in the collection, increases the collection rate, and also reduces the amount of energy needed for collection.
