I really liked even prepping for this. This is a great way to end the parnast series. My players really by the end of the series felt for the people and were really interested in coming up with solutions. They really worked together and actually split up alot of duties based on their strengths. I really had to limit time and gave them 2.5 hours to prep and about 2 hours for the second part. This really crunched the players to work fast. They were actually panicking a little about getting it done. This created the urgency to prep, collect their allies, prep the town and come together. The fights, as everyone said, are no joking matter. They are tough. I took what someone said and since my players were almost apathetic about letting Chandra leave and die, and they went to extra effort to get her back, I gave them some healing services from her. The last two waves are rough on the players if they are range low, but since my players convinced Thornacious to help, it made it a little easier. (7 players and 4 of them have high charisma, they were able to easily sway allies, and townsfolk).
Summary: Great Adventure, great finish but be prepared and know your players. No laughing joke for levels 3-4.
