haha, i actually looked on the walkthrough straight after i made this thread. I beat the boss with ease and the behemoths and killer mantis' were surprisingly weak and couldn't lay a finger on me until i found a couple of behemoths which were berserk.
Thanks guys, and now i am so not looking forward to going inside Giruvegan. By the way--what level were you lot?
