The Thorium Mod adds 8 new ores to the game, as well as two vanilla ore variants, which generate in the world and are used to craft a variety of tools, weapons and armor. Thorium Ore, Smooth Coal, Life Quartz, Magma Ore, Aquaite, Mossy Gold Ore and Mossy Platinum Ore generate naturally, while Lodestone, Valadium and Illumite generate after certain conditions are met.
- Spawning Lodestone and Valadium requires defeating Coznix, The Fallen Beholder. Upon his death, there is a 50% chance that each generates in the world. Each ore can generate a total of 3 times, requiring the Fallen Beholder to be defeated 6 times to fully generate all the ore possible.
- Spawning Illumite requires defeating Plantera. Upon her death, your world will automatically generate Illumite in Mud Blocks all through the underground. Illumite can generate a total of two times, requiring you to beat her twice to fully generate all the ore possible.
- Mossy Ores drop their vanilla variant when broken, and cannot be obtained legitimately.
- 22.214.171.124: Medicite no longer generates into the world.
