to be attacked, for they would certainly defeat any moderately tough adventurer party specified by the author if they all tried a massed and well-coordinated attack." He also wondered about the placement of the kuo-toan shrine: "There is great hostility between the Kuo Toa and the Drow, so it is surprising to find the main Kuo Toa stronghold in the middle of a thoroughfare used by the Drow as a main route. It is also surprising to find the Kuo Toa still in business, given the seeming superior military power of the Drow, but who knows?" Anders felt that the adventures contained a great deal of imaginative material, "but while the writing style is by no means poor, the combination of florid prose and new ideas makes a text which is relatively difficult to read. Gygax does not make a regular practice of organizing his text to help the poor GM pick out the important information quickly." However, Swenson concluded that this is overall a worthwhile adventure. "The plot is interesting, and everything is well detailed. Aside from the problems I have already noted, the adventures are interesting and generally of superior quality."
