I am afraid I must be the lone dissenter in the review of this particular adventure. First, on the good side. The traps and challenges presented in this module are very creative. They would challenge even some of the most experienced and paranoid players out there. As with the classic Tomb of Horrors, there are a myriad number of ways to die if the party is not constantly on its toes.
The problem comes when the adventure is over. IN MY OPINION, the characters do not have much to show for things when all is said and done. On a risk-reward type of basis, the risks for outstrip the rewards the characters receive, especially when dealing with the lowest level of the dungeon.
With some retooling, the adventure could work, but as it stands, it was a bit disappointing.
