Without encounters, dungeons are just some twisty passages with the occasional bit of loot. It's the monsters that make the whole endeavor interesting. And if you're struggling to come up with new ones for your party, let me introduce you to Endless Encounters: Dungeons, a new RPG supplement up on Kickstarter.
From the campaign:
The old school has returned! Back to the good ol' days of monster hotels and dungeon crawling we go!
