I thought this adventure was fine (to run). It wasn't particularly outstanding in any fun or unusual ways, but it also didn't have any errors or awkward patches I had to fix-up while preparing it. It is pretty much just a combat module (with a smidge of opportunity for the party to socialize with an unusual mephit). Difficulty-wise, I don't think my players ever felt like their characters were at significant risk (the final boss managed to corner them all in one of the huts where they'd tried to rest, so they had to stay in range of her abilities, but the saves weren't too bad for them). This is another module where the enemies don't have a lot of good options against archers and ranged spellcasters.
