Rock Gas

Rock Gas is an element produced by a Volcano after it has been tuned five times. In practice, it is the gaseous form associated with that heavily tuned Volcano output, and it appears as a special post-tuning product rather than a common naturally occurring material.

Because it is tied directly to Volcano tuning, Rock Gas is primarily a byproduct of endgame or advanced geyser management rather than a resource that players normally mine or refine. Its appearance depends on the Volcano reaching the relevant tuned state; once that threshold is met, the Volcano’s output changes phase into a gas.

• Rock Gas is associated with a Volcano that has been tuned five times.
• It is the gas-phase result of that tuned Volcano output.
• It is not described as a general-purpose refinery product or a standard world element.
