DatapacksJava
Iron Upgrade
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This Datapck adds a simple recipe to upgrate your Iron Equipment to Diamond Equipment in the Smithing Table. You only need an Item Frame as Smithing Template the Iron Tool you want to upgrade and one Diamond. It works for all Armour parts and all Tools.
