Well, I found the body and all that, made a lot of wyvern potions and the histachii potion and poisoned 3 of the " pure, fresh water" basins on the lowest floor, plus got past Sseth's Eye, across the drawbirdge, and killed all the Effeets(annoying, those). There is a locked door "with no obvious means of unlocking it" in the bottom right-hand corner of the lowest floor, and the other door im convinced is linked to poisoning the basins, but I only found three, and the forth illudes me. ALL I WOULD LIKE is the way to find the forth basin(or the means of unlocking that door) THANKS!!!
