That's a good point. In my current game with a big group they are adventuring on Tarterus, these characters' first experience of the outer planes. They are seriously powerful people, but here they have to adjust their thinking and everything is a whole league more dangerous. That keeps it viable and interesting, as any complacency they might have had going in to the adventure has quickly been replaced with genuine fear.
