Crystal Cavern is a zone added in the Crystal update on September 21, 2018. It requires 20 Rebirths to unlock.


Layers are made from Cave Stone. Cave Stone is the most common block, and Crystal Stone currently gives the most coins per 1 block in the game. The NPC (non-playable character) quest giver is ObscureEntity. His quests are currently the most difficult.


Crystal Cavern is the only zone based inside a cave. It is decorated with pillars and glowing crystals of various colors. The portal is also made of pillars. Crystal Cavern's shop is shaped like a pickaxe and its sell area is a crashed minecart filled with gems. The path consists of brown planks/bricks and is lit by stone braziers.

The Mine



  • The music used at the surface of Crystal Caverns is the music you hear when mining at layers 4-5 in any world prior to the Sir Minesalot Event.
    • The name of the music is called "The Broken", and was composed by BSlick.
