Ghoul lord area is found by doing the "cult of the unseeing eye" quest. When you manage to descend into the pit of feeding you'll notice two doorways on the other side of the bridges. Trough that doorway is the ghoul lord area. The bracers are found in one of the heaps of rubbish in undead "party zone".
First time through I encountered a Greater Mummy as toughest foe ... so I thought it would be a cakewalk on my second time, until some joker cast a time stop. At that point I noticed the Lich among the enemies ... I reloaded and used a different tactic. Still, the Mummies, Skeleton Warriors and the Lich made for a somewhat tough fight.
The lich and greater mummies only appear if you are high enough in level. It is reffered to as monster scailing (something like that), it's so the game can never be a walk through
I'd have to get drunk every night and talk about virility...And those Pink elephants I'd see.
It just depends on the level of your party. Just start turning undead with your cleric and you should be alright: if you encounter a lich, your cleric should by then be powerful enough to turn him as well; and with Viconia....yeah,fun to have a lich under your control!
