1 - Here lies a door up to the surface. It is guarded by Drow and shouldn't be used until you return the Dragon Eggs to Adalon. 2 - You'll fight the Kuo-Toa Prince in this room. Grab the Bracers of Blinding Strike and a vial of his blood before leaving. Additionally, if you have the tainted tadpoles from area #4, you can place them in the water here with the healthy tadpoles. 3 - An altar to Demigorgon is at the end of this room. You'll need a sacrifice in order to get any response out of it, tho. Simply conjure up a monster (Spider Spawn doesn't work) and have him stand by the altar. He'll be sacrificed and you'll be fighting five Demon Knights, loaded with awesome equipment. You'll get yourself a Soul Reaver +4, Armor of the Hart +3, and the Girdle of Frost Giant Strength needed for Crom Faeyr. 4 - Within this room is a pool of water that contains some tainted Kuo-Toa tadpoles. Later, in the Kua-Toa prince's room (area #2), the tadpoles can be placed in water with healthy tadpoles. This will make the prince a lot easier to defeat.
