Roll 4 Ruin: Classic Dungeon Generator

By the gods, what is this?! 

•This generator creates quick, easy-to-use dungeons for the fantasy TTRPG of your choice. Use it while prepping, building a sandbox, or even as players or you yourself explore it in real time.

How to use this strange magic?

• Start by rolling a D20 to define the dungeon entrance.

• Each square is 10×10 feet.

• Each opening (marked by arrows) leads to a new room. 

 • To create new rooms at openings , roll 4d6 and use the matching tables for room type, shape, and content (see below).

• Rotate the rooms to fit the map and connect properly. • Use extra rolls if required to add more room details.

 • Tables are labeled A1, D3 to help with cross-referencing.

• Stairs lead to deeper floors with bigger treasures and more dangerous foes !

• Use monster tables that fit the floor level (e.g., D3 for the first two floors of the level)

Where does it all end?! 

• If you want to limit dungeon size, pick the lower combo of the two dice from your layout roll (e.g., 6 & 1 = 16, not 61).

We hit a structural wall?! 

 • If a new room shape overlaps existing rooms, adjust the new rooms shape to fit the space and connect room openings if existent.

Too many monsters, Mr. DM?!
• For more consistent enemies, roll 2D20 and use a monster type already found (or the first roll).

You rolled a what now?!

• Use logic! You can pre-roll the dungeon and of course still adjust elements or tweak them on the fly if it breaks immersion or consistency .

• These tables are just a starting point feel free to change, expand, or trim it as you like. Make it yours.

• And Most of all have fun
