robertsconley said:For sentient beings I use the natural social to organize my levels. A dungeon is low level because it is a guard outpost in a cavern with only regular warriors, sergeants and maybe a captain. A high level dungeon is high level because it is the primary seat of the Great Evil Lord Divolic.
For animals/monster I use a basic ecology layout where the top predators are fewer in number and more scattered than their prey. And each regions has a unique mix of creatures from low to high CR.
This is pretty much exactly the type of thing I've been trying to describe.
