Get this expansion first!
This expansion includes all the main cards plus a helpful health meter and some random extra baddies. This expansion plays on its own. The only thing missing from the original game is that selection of heroes. In this game the bard, the princess, the ninja and the necromancer all have some very nicely balanced abilities.
An excellent, easy to learn, push your luck game where players dare each other to push the hero into the most dangerous dungeons and then watch with baited breath as the most courageous player faces the odds.
