Aetherium

Dependencies above are only for v0.5.0_beta and later

A Fabric mod inspired by the idea of Equivalent Exchange, built with its own progression, balance, and economy.

Overview

Aetherium is am alternative to ProjectE, designed for Minecraft 26.2 and future releases as development continues.

Rather than recreating ProjectE, Aetherium introduces its own interpretation of item transmutation. Every item has an Aetherium Value, allowing it to be converted into a universal resource and back again. Unlike ProjectE, Aetherium focuses on a steeper progression.

⚠️ Disclaimer

Aetherium is still in active development.

Not every vanilla item and block currently has an assigned Aetherium Value. More values will be added over time, with the eventual goal of supporting every vanilla item that seems to make sense.

❓ How It Works

Items can be converted into Aetherium, which can then be used to recreate other learned items.

Items → Aetherium

Aetherium → Items

Currency Crystals (Some are not yet obtainable)

• 1 Aetherium Dust = 0.001 Aetherium
• 1 Aetherium Crystal = 1 Aetherium
• 1 Aetherium Ingot = 1000 Aetherium
• 1 Aetherium Block = 1 Million Aetherium
• 1 Compressed Aetherium Block = 1 Billion Aetherium
• 1 Double Compressed Aetherium Block = 1 Trillion Aetherium
• 1 Triple Compressed Aetherium Block = 1 Quadrillion Aetherium
• 1 Quadruple Compressed Aetherium Block = 1 Quintillion Aetherium
• 1 Quintuple Compressed Aetherium Block = 1 Sextillion Aetherium
• 1 Sextuple Compressed Aetherium Block = 1 Septillion Aetherium
• 1 Septuple Compressed Aetherium Block = 1 Octillion Aetherium
• 1 Octuple Compressed Aetherium Block = 1 Nonillion Aetherium

Also the Max Stack size for Currency Crystals are 1000

💡 Inspiration

Aetherium draws inspiration from ProjectE (Equivalent Exchange 2) while taking the concept in a different direction.

It is not a direct copy, but its own system.
