The Battle for Berimond is an event that players get as an option in Good Game Empire after level 30. Earlier you used to get Decorative items worth 60 Public Order if you were a part of the winning team.
Ideally it has 2 different kings competing against each other and you have to fight for one of them. If your side wins, you get the PO. Now the Battle for Berimond gives you Equipment instead of the 60 PO item. If your alliance does not have a capital, then it is a good way to get KingsGuard also.
Everyday I get questions from various players of the game, where they want to learn how to attack. I visit their castles and OPs to check their development and then wonder, why do people always want to jump to level 10, instead of learning the basics. The most important aspect of this game is to develop your castles and OP correctly. And your focus should be on that. What I am about to suggest is a long term plan. It takes months to achieve it, and there is no shortcuts to it.
With the recent update we got this new Equipment deal. At first glimpse it looks very confusing and scary but if you spend sometime around, you will find it is not that tough as it looks. Yet, I have my basic guide for you, while I will keep upgrading from time to time.
