Hellstone

Overview
Hellstone is the sixth layer in Elemental Mines. It is a secret layer, only accessible through a very complicated process.

To access this layer, the player must first dig to the very bottom of the Obsidian layer. They must then strip mine in the Obsidian, occasionally clearing out the Obsidian below them. If they spot an Obsidian block where Bedrock should be, they must mine it to enter Hellstone.

Physical description
Hellstone appears as a pink Stone block. In Studio, it has material "Slate" and color "Persimmon."

Badge description
The badge description reads: "You have discovered the secret of the Elemental Mines. Go reap the rewards of your adventure," referencing the fact that this is a secret layer and that this is a perpetually infinite money farm.
