This cavern generator creates organic cave complexes for tabletop roleplaying games. It forms connected chambers and passages, identifies notable areas, and can populate them with encounters.
How to generate a cavern
- Open Configuration to choose the cavern type, size, passage character, natural details, challenge, encounter mix, and grid.
- Keep the defaults for a quick random cave, or create a lair, main passage, labyrinth, or crawling complex.
- Select Generate Cavern. Choose a numbered area to inspect it, or open the complete encounter list.
- Save the cavern and its encounters, or transfer it into an Adventure on the Legendary Players Guild virtual tabletop.
Designed for natural exploration
Use open chambers for a creature lair or increase twisting passages and roughness for a longer underground expedition. Regenerate to create a new layout without changing your selected style.
