I've enjoyed running it. I think one of the hardest parts for the groups was making them think outside of the box on how to actually figure out where to go. People were making checks to learn about the Cauldron and had fun with that. I had a player that has high checks in things like history and seemed to shine with being able to explore that aspect. They did take the social side to things and the had a lot of fun. When they finally realized what the Cauldron was... they were pretty blown away. It was a pleasure to run.

An interesting module that features a new creature from Mordenkainen's, it is another great addition to the series. The [SPOILERS] mutation pool part seems a bit unfair with some awards, such as the result of getting 1 on that roll, but otherwise I have no qualms with the module.
