Crystal

Crystal is a mined resource found on crystal tiles in the cave biome. It can also be obtained by cutting down Crystal Trees, making it available both from underground deposits and from cultivated sources.

Because Crystal Trees can be grown in a Large Garden if you bring back seeds, they can serve as a stable renewable income source once established. Crystal can be exported directly, but processing it into Glass Craft raises its selling value and opens up more export options. Since the conversion efficiency into Glass Craft is very high, selling it after processing is usually the better choice.

• Source it from crystal tiles in the cave biome or from Crystal Trees.
• Bring back Crystal Tree seeds to set up renewable production with a Large Garden.
• Direct export is possible, but making Glass Craft is generally more profitable.
• Processing Crystal into Glass Craft is also useful for widening the number of buyers who will accept it.
