whenever i buff them up all the stuff gets dispelled as soon as they enter the chamber and as my rogue has no spells i cannot buff him in the chamber itself. as for my paladin, by the time i have cast all the buffing spells i am already being beaten to a pulp. and my cleric mage gets down to less than half hit points before she can cast any decent spells. i have just tried my rogue using darts but they only do 2 or 3 hp damage each time and this is just no where near enough to get through it before kill him by having lucky hits as i'm running around the place and there are only 20 darts which is not even enough to kill one of the monks.
edit: managed it now, although largely thanks to what i think was a bug. i tried my rogue and she got one of them down to almost dead before dying on me, then instead of reloading i decided to just continue with my paladin. when i entered, it still dispelled everything but this time, for whatever reason, there were no flame strikes so defensive harmony and divine power plus a longsword destroyed the bronze monks in no time at all as i didn't have to worry about running around avoiding the annoying flames. it must have been a bug but i'm not going to complain as i was getting fed up with it
thanks for the help.
