Overall, this was a fun module. The beginning of the adventure, which involves infiltrating a Red Plumes base with Felratha's Merry Minstrels was a lot of fun for the PCs to create costumed personas for their characters and also show off their character's talents. At the same time, this part of the adventure allowed the PCs to engage in a lot of roleplay, subterfuge through the halls, and swashbucklery combat in the Red Plumes' dining hall. The encounters for navigating the Waydown River seemed to go on longer than it needed to, especially if the party has no multi-target spells (which is still tricky since there is the risk of nuking your own boats in this part). The final part with the kuo-toa shrine gets things exciting again, with some memorable combat encounters amongst Underdark occult ambience. If the PCs like to RP more, they might even get an unlikely "friend" to help them in the final encounter.
