This module was fun and was a nice diversion from the usual enemies. The players figured out that they needed to go into the swamp pretty quickly but there characters were not thrilled with that plan. They were even less thrilled when the two rogues were swallowed by the giant toads and almost died. Still, they managed it and were sufficiently freaked out about the acid melted corpses and items. I linked the end of DDEX1-06 explicitly with why they needed to go into the swamp and it seemed to work out well. Encounters in the swamp were interesting and challenging. Would recommend, especially if you want to scare your characters with drowning by grappling lizardfolk that can hold their breath far longer than most characters.
