This series has scored a hit with every issue. One of the most useful features is the modularity of the content. You could play an entire game in the Dolmenwood or use various aspects of it to enhance pretty much any fantasty setting, from gritty low-magic to the highest of high fantasies.
This issue is the best of the lot, an encouraging sign that these are getting better and better. A particular highlight of this issue and the previous is the Abbey of St. Clewd. This location gets creepier and creepier the more it is explored and embodies the history of the setting in a way that allows for excellent player engagement.
The Attacorn is also a great monster. It and its siblings could provide the basis for an entire campaign.
