Aetherium
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.


Adds a resource slightly stronger than Netherite called Aetherium.
- Aetherium Shard Ore generates in a very small portion of the Overworld, only between Y -16 and Y 16. It does spawn in all biomes.
- The ore can only be mined with a diamond pickaxe or higher.
- Each ore only drops one shard, with or without fortune.
- Put four shards and four diamonds together in a crafting table, shapelessly, to create an Aetherium Ingot.
- Then combine the ingot with an Aetherium Smithing Upgrade and any Netherite tool to make an Aetherium tool.
- Crafting recipes shown in gallery.
