I played in it and we actually managed to do everything in about the best way. We beat it on the 19th round. First one our group has beaten on the first try.
It is not too original, but it is a good lair assault.
I ran it twice already.
The first time, had a group of five players. They managed to defeat the challenge though it was tough they managed to pull together and finished with a few rounds to spare.
The second time, I only had three players. One of the guys played a second character and another was his first time playing 4e. Surprisingly, only one character died during the challenge. They were unable to defeat the challenge as they ran out of time.
Overall, I enjoyed the Lair Assault and will miss not having any more of them. I hope WotC creates another similar program for this year.
Was there a secret to keeping the party together in going from room 1 to room 2? Ours was scattered all over.
Our group ran out of time at 20 rounds, and I spent most of my time sitting around doing nothing because the priest had me perma-dominated. Teaches me for having a 19 Will Defense, but it still wasn't very fun. Dominate: Touch the pillar. Dominate: Touch the pillar again. Dominate: Listen to the whispers and gain a madness effect. Dominate: Do it again. etc.
