I ran it this past Saturday. It went quite well, we all had a good time. The only moments where there was tension, were:
1- the bar fight with Ionovicus (sp), unless you have a character who is very specialized in unarmed combat, or mid level +(my group was level 2), Ionovicus is likely to make short work of his opponent. Fortunately, the thief with the questionable morals was quick to sneak attack the brute once the brawling PC dropped.
2- my group has played D&D for over 20 years, and it's been a struggle to make them understand that Conan RPG is not D&D, (they tend to refuse to flee) so once the battle at the bowl began, I had a dificult time convincing the party to flee into the tunnel, resulting in the thief and scholar being mowed down by missile fire. (they learned their lesson, you can bet your ass they're going to be running and screaming like little girls next time). The remaining character fled quickly into the tunnels. After watching his friends go down, it didn't take him long to run away once the stones came alive. He and Bogdan manage to cause a cave-in which stopped the stones.
Other than these two instances, the rest of the adventure went pretty much according to plan, except that Oleska fled back to Arenjun in the end. Now the party has decided to return to the Maul, and come up with a plan for sneaking into Oleska's Palace and killing him.
One other thing, we discovered that armor is wonderful thing. Just asked the noble, who barely had a scratch while the rest of the party was damn near chopped to bits or pincushioned.
