I picked up a couple of games (ok... alot) over the holidays for my family and I to play.
One of these games was Cave Troll. We tried our first game of it last night, and we had some confusion about when/how to play heroes and monsters.
1) Do you play them as part of your four actions and place them out on the entrance? Say I wanted to play a dwarf, I could place him out on my turn OR
2) Do use play them only when you have one of their cards?
We played a combination of the two for the time being.
