now i am no beastlord main or anything but i found that with a temp on me and pet if possible frontier mountians is amazing experience, i can ding 30-32 there on any character in about an hour and a half. for beastlord easiest exp is to go to the giant fort and pull with drowsy, tank it and cast yourself a spirit strike or two and you have yourself a giant down. another good thing about this zone is that your 30th level pet can tank just as well as you can with spirit of the inferno on it sometimes it even takes down a giant before i can.
