About this Mod

Have you ever noticed how repetitive mining can be? Vanilla only has so much variation before it all starts to blend together. However, with Spelunkery your woes are no more!

REQUIRES MOONLIGHT!
Spelunkery has three main goals:
To tweak material progression to enhance the experience of mining.


To populate the underground with new landmarks, points of interest, and variations on ore generation to strengthen the variety of caves.


To provide novel and useful tools to create exciting experiences when mining or exploring.



Spelunkery has been extensively tested for compatibility with No Man's Land and Create.
