By the way guys, I started running my group through CD1: Terror and Blasphemy. So far, they did rooms 1, 2, and 9. It was a blast. They also had an encounter with Vlask, here's how it went:
SPOILERS:
They had to bash the southern room 2 door, being deprived of a rogue. Of course, they got zapped by the lightning trap on the door. It took them a while, so I decided that Vlask had plenty of time to ready himself (Invisibility, Blinking). They are 3, and the sorceror always come last in the marching order. So I ran Vlask as described in the adventure. He sneaked on the sorceror, bashed him for 47 damage, the sorceror barely got time to glance at him before Vlask blinked away. They were quite frightened by the encounter. Now they are oh-so paranoid walking in those corridors.
CD1, my friends, is quite an achievement, of the highest quality. The depth of room 2 really set the mood for the adventure. They're hooked. Next game session is in 2 weeks. I could smell their fear when I told them that a dozen or so Rat Bastards DM's worked in cooperation to bring this little gem to life. I have never seen so many listen, spot, search, and whathaveyou checks requested by the players.
And every time they go in a room, I say "Oh, and this one is brought to you by [insert collaborator's name]". Very funny.
