I know of the MOB you are speaking of. Off the top of my head I want to say it is Numa 2, I know you take a left & it is a somewhat open field full of bad guys next to there little encampments, the Mob mentioned is 2nd or 3rd in on the Right if I remember correctly. It has been a couple weeks since I have ran Numa but that 1 bad guy has always had an extremely high amount of Hit Points for as long as I can remember. And he is just a regular mob, I always run past him to save time.
