About six rounds. But they were taking there time to enjoy. Two of the five (Scout and Rouge) swung into the second story in the room with the monks, destroyed them in about a round and a half, like I said taking their time. While that was happening the Monk and the Sorc kicked down the main door and fireballed both sets of hiding archers. The cleric walked into the next room, eating an apple, and disarmed the balistas... The monk ran upstairs, kicked a new doorway into one of the walls to the torture chamber and killed Jil. Then the looting commenced.
They had fun. I had fun. They got to act like Rambo, I got to sit back and dream blissfully of the upcoming chapters where they wouldn't be able to do that again.
