I think I would like cards where when drawn, the player get to choose to get some small reward (fate, spell etc) or add power to the inner region, portal of power, Lord of darkness and such. Meaning that the door need more craft or strength to open, the wherewolf is more powerful, more pit monsters etc etc. Ofcourse the player would choose to increase the challenge on the craft-way if he is planning to use strength himself, unless another player are more powerful in strength and need to be stopped, while the player tries to get ahead of him.
It would be a bit like Cerberus, adding obstacles or increasing the obstacles that already are there.
