Hi all,
Yes exalthim2 you are in the right area.
you have to first clean out the areas which are located to the north,south,east and west of baddies and in each of those areas you will have a pillar on which to activate a switch. Once you have activated all the switches you will then have a new area where there is a big boss and the armor is in the chest there.
Don't forget to pick up the (forget what it is called) after you kill the big guy to bring back with you.
I hope I have remembered this one correctly.
