I just bought the module and plan to run it as PbP soon. However, reading through it, has this actually been playtested using the PFRPG rules? It seems many of the quests in the first Act are overly difficult for a party of four 1st level characters. For example, the quest "Jack of the Weirwood" has the players battling one CR 4, one CR 3 monster and eleven (!) CR 1 monsters. Sure, the 11 fauns will scatter if the PCs manage to defeat the Satyr, but given the fact the Satyr has 44 hit points, AC 18 and DR 5 that is a pretty big "if".
Looks like a pretty sure TPK to me, but maybe I'm missing something?
