Editing Nalua Valley (section)

==== Upgrade system ====
In Nalua Valley, tools and armor from wood to deepslate are freely craftable. But you don't have crafting recipies for copper, iron and diamond tools, weapons and armor. In fact, you have to earn minegeld and ores to be able to buy an upgrade gem to create a raw tool, weapon or armor piece of the next level. Starting with copper, then iron and finally diamonds, these upgrade gems increases in price. Having an upgrade gem, you can craft a raw tool, weapon or armor piece. To use it, you will have to forge it in the upgrade forge.
