About the Mod
This mod adds a heavy endgame Uranium ore tier sitting above Netherite. Instead of just being a standard green toolset, Uranium is dense, unstable, and takes a ton of Iron to stabilize before you can safely forge it into gear.
How Progression Works
- Mining: Find Uranium Ore deep underground and smelt it down.
- Stabilizing: Craft a Stabilizer using Iron to turn it into Uranium.
- Forging: Once stabilized, you can craft your Uranium Pickaxe, Axe, and Sword.
Tool Stats & Trade-Offs
Uranium gear is meant to feel powerful but heavy and unstable:
- Heavy Weapons: High damage output, but a slow 0.5 attack speed—every swing hits hard, so don't miss.
- Durability: 1100 durability across the set.
- No Anvil Repairs: You can't hammer radioactive metal on an anvil to fix it.
- High Enchantability (92): Super easy to roll top-tier enchants at an enchanting table, though Mending is weakened on Uranium gear so you can't just infinitely farm XP to keep it alive forever.
Planned Updates
- v1.0.1: Adding actual radiation hazards when handling unstabilized Uranium or hanging around blocks too long.
