About this Mod

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.

Frequently Asked Questions

Aetherium server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.21). You can switch loaders with one click in the panel.

Is Aetherium compatible with fabric?

Aetherium officially supports fabric for Minecraft 1.21, 1.20.2, 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Aetherium – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Aetherium consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
