I have played this module 4 times and DMed it twice. Lots of RP in the first half, and lots of combat in the second half. My experience is tha players tend to burn through resources (i.e. spell slots) WAY too fast, and this module teaches them to pace themselves. I had a total blast RPing the NPCs as a DM, and as a player, it was great to RP the module different ways without giving things away (player knowledge versus character knowledge). If your party is cruising along, just upscale the final fight and make them sweat!!! Probably my most favorite Season 1 adventure. Many other DMs fall back on this adventure when call to duty suddenly.
