Ok his protections change with his colors. When he isa fire demon (red use Ice cold weapons. When he is air use acid poison, when he is ICE use fire and when he is in slime form lighting. The best way is to keep summon monsters between you and him and use range with appropriate arrows/bolts and spells and wands. AS for the slime door. you need to go to the room striaght north to get key for Air room then do air rooms and liabray to get key for slime then go to the slim library then open door between air room and library then slime doors (both this wil blow slime poison into slime library) then kill slimes and the giant snake then open door to ice rom the slime poison will be blowen into the ice room and work against the ice guys. (weaken them but not kil lthem. then open doors to fir room and try to get the elementals to follow you into ice room (which kills them) then kill the fire giant he is immune to everythign till the elmentals are dead. Hope this helps. All of this is written in the notes laying around the rooms.

Search the libraries for a key to the door - turn the fan up to max - the gasses from the slime lab will now be blown into the ice lab - the icegolem will then be vunrable

like Ar-Cunin said, but remember to open all the doors. Once the gas cloud is in the Ice Room, you can beat up the golem. The fire giant (next) is also tough, since you have to get his elementals to follow you into the ice room (they freeze). otherwise he regenerates. That Ice Golem thing made me really angry too, until i read some of the Library Notes...
