So, let me say I REALLY like this module. I have not run it yet but plan to this weekend. Really good mix of roleplay and combat and certainly plenty of room to modify as a DM. I love the Battle Stat Tracker in the PDF. However, this review is mostly for the fantasy grounds module.
I really like the variability of the monsters and the utilization of some cool monsters that aren't all that common such as the Flesh Golem, Bone Giant and Bone Naga. Speaking of which, the final battle I have a feeling could easily be a TPK for a party of four, 6th level characters. It will certainly be extremely challenging!
All in all, I would absolutely rate this as a 5-star. I did find a handful of module issues with encounters, maps and parcels which I submitted to the author and hope he corrects them. I considered rating the module 4-star because of those issues, but ultimately rated it 5-star as the value I feel like I received for the price is awesome.
I highly recommend this module.
[5 of 5 Stars!]
