My friend Sam, who I game with every week, pointed me to this saucy little minx (thanks, Sam!): The Dungeonomicon, a lengthy thread on the WotC forums that attempts to justify, explain and tweak dungeons, along with a variety of other fantasy RPG staples.

It’s broken down into sections, but the original thread has no direct links to each section. Let’s remedy that by linking to the foundation posts individually here.

There’s a lot of interesting food for thought in this thread — hopefully you’ll get some good mileage out of it!
