Create natural cave complexes with connected chambers, encounters, and configurable layouts.
The type of complex, how it is entered, and how the map looks.
The shape of the rock itself, each from 1 to 12.
There is a 1 in 6 chance an area is empty before these apply; a further 1 in 12 chance it combines two of them.
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.
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.
