4 out of 5 rating for Council of Thieves Adventure Path
Set in Cheliax, this path has an definite infernal flavor. It is also a city adventure, with only half of one book set outside town. I have played this as a part of another campaign, and cut away about half to do so, but I loved the parts we did play. Lots of role-playing moments and cinematic situations, this is probably one of the most scenic of all adventure paths. It gets a little long, tough. Perhaps more so because I cut away some parts - most all of what I kept was about devils, and my players were wishing for some mundane encounters by the end.
