I don't want dungeons to be harder. I want dungeons to be more varied and interesting.

For example, small, non-fatal interactions with a dungeon's environment: The binding traps littered throughout Hullbreaker Isle. The tornadoes and waterspouts of Neverreap. The water faucets in Saint Mocianne's Arboretum. The wandering tonberries in Wanderer's Palace. Etc.
