How to do an EF....hmm really hard to explain. Get yourself alot of people, make sure there is one leader, and then u must go to the specifc zone they send you to to find the beastmen's banner. DO NOT CLICK IT UNTIL EVERYONE IS READY! When u click it, NM's will come out and simply u must fight them. Going with good stragegy is a plus ^^. After the fight touch the banner again and your lvl cap will be lifted. I only did the one for Zulkhem, A.K.A Valkrum Dunes and LVL cap was 30. Thats all i got ^^
