Level 2 Watchers Keep - HELP!!!

[robo donkey]

I am stuck on level 2 of Watchers keep. I have completely ransacked the 4 libraries and entered the air lab. Each time I turn the wheel 4 air elementals (2 lesser and 2 greater) turn up along with some guardian of air. I am at about 3000000 EXP and I defeat the elementals but when I leave the lab through the fire library 3 fire giants are waiting to kill my flagging party and if I stay in the air lab what look like chain lightenings wipe me out. Please help me.

Perhaps an Invisibility 10' radius spell might help you sneak past the giants. Armor of Faith will reduce the damage your priests suffer from physical attacks. You say your party has 3000000xp? Are you soloing; if so, which class? Area effect damage spells versus the giants? Summon some help, maybe?

simple first you kill the air elementals get wand crank up power on fan open other door go to the south end library grab key unlock lower slime room door the the upper. poison cloud leaves room and slime stuff easier to kill. then open door to ice golem room from right side. poison cloud now makes the ice guys vulnerable.kill them grab staff and youll be able to open upper ice room door. the go to the south end fire room. there are 4 greater fire elementals to kill. if you kill them by weapons they keep coming back in the pit. you have to lure them away 1 at a time to the now open ice room.the elementals freeze in tracks and die instantly thus they stop coming back do that 2 all 4 of them then you can finally kill the fire giant. thats the easy part of level 2. now you gotta kill the chromatic demon. hope you got lots of +4 or 5 weapons to kill him with. (most effective way to beat the chromatic demon) get 2 tanks with lots of greater whirlwind attacks and and ALOT of healing potions your gonna need them unless you got a good cleric in your party. after along lengthy battle he will finally fall.
