Haunted Crypt Generator

There's nothing new under the sun, but that's just fine. Nothing I've posted below is really that original, you could come up with all of these ideas yourself, arrange them in a roughly applicable format, and away you go.

However, I've been inspired by a particular style that fully generates a tiny dungeon. And honestly? This one works pretty damn well. I've cribbed and mangled diseases and curses to add a bit of sting, and the wandering monster tables are short, pithy, potentially lethal.

I've been stuck on a boat with a handful of dice and scraps of paper for quite a few days, and I've been throwing piles of random characters down the maws of these insta-dungeons. It's basically solitaire with more rules, with a bit of Dungeon Robber thrown in for good measure. I thoroughly recommend it for a bored afternoon. Combine it with a GM Emulator (1d6: 1- No and, 2- No but, 3- No, 4- Yes, 5- Yes but, 6- Yes and) for those pesky hard-to-resolve questions, and go for your life. Or death. Whatever.

You might be tempted to bring nothing but Clerics down here, but each one immediately summons one Grue. You’ll be fine. Don’t turn out the light.


This crypt has 1d4+1 floors, each with 1d4+2 rooms

If no stairs are rolled on this floor, then the next random encounter emerges from a hidden set that you missed.


Roll a Wandering Monster check every 3 hallways you move down, once during lunch and twice overnight. On a 1, it’s a fight. On a 2, you see a Glint. Take the turn and roll d6. 1/2- Monster, 3- Trap, 4/5- Nothing, 6- Treasure (roll 1d12 over both tables)
