I went into this scenario expecting to have some fun with my character. Unfortunately, that did not happen.
The scenario uses mass combat mechanics for at least half the game. You take control of an army and have a nice game of checkers. In our party, a player got his army decimated real quickly and was out for most of the game. For myself, I also lost my army fairly quickly (terrible rolls) and ended twiddling my thumbs.
Once we finally got to play our characters in another part of the scenario, we encountered a special swarm of Tieflings guarding an entrance. The swarm sent volleys of arrows which did "auto" damage to players with no way to avoid. Unfortunately our party was low level and we had no way to deal with swarm type monsters (very unfortunate for us).
I was disappointed with the scenario. If I had the chance to replay with another character, I would avoid this one.
