Well, for one the "big fight" Fiends vs Mind Flayers on the Nautiloid is NOT something that you are *supposed* to go through. In fact the game advises you quite strongly against joining the fight.
A lot of people attempt it anyway, because it's not that hard if you know how to leverage a couple of tricks.
