The end wasnt too hard, I just swarmed it with Hobbits to keep it back so it took forever to get to my castle, infact it didn't even make it to my castle...Also used an almost equal amount of dragons and angels, but angels work better and kill stuff behind it so it rakes in mana for you And -always- had wizards being pumped out...and sometimes a golem or few....Also i made sure all my arrows (including special ones) always came down on it from a high angle......
