Someone sent me an email the other day, requesting strategy tips for Fire and Water, so I'll be playing some games tomorrow as a refresher.
IMHO, it's the most difficult of the expansions available for Dungeon Twister. It's got some really good characters who will see a lot of play in tournaments, but the difficulty of the rooms combined with the uniqueness of the characters makes for an extremely difficult set.
I may also be fairly quiet here over the next few weeks - I'm gearing up for GenCon. I do this by playing games. And studying rules so I can teach people to play games without making any significant mistakes (I'm human, so I do make mistakes - the goal is to make them as small as possible).
I take it very seriously, being a member of a demo team.
