make sure you clean out the whole catacombs. there are more levels.
and hit & run tactics aren't cheating <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> except from you enemy's point of view, but who cares about him <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
and about the orcs killing you: boost up your armor with better armor ( <img src="/ubbthreads/images/graemlins/mage.gif" alt="" />), drink potions or scape with your teleporters (and that again is only cheating from your enemy's point of view ^^)
