Raranium
by monokrane
Raranium adds a rare ore that generates only inside veins found beneath hot biomes, along with a few related materials for tools and building.
What it does
The mod introduces new ores and several custom biomes while leaving the vanilla world largely intact. Raranium is the central addition: a rare ore that spawns exclusively in Raranium veins under hot biomes, and the tools and armor crafted from it are described as offering superior performance. Darkstone is a more common ore found in large veins, and smelting it produces Lightstone, a versatile building material.
Lightstone can be turned into many decorative and functional blocks, including doors, bricks, trapdoors and fences, and it also serves as a crafting material for Lightstone tools and armor. Steel is a separate material made by combining iron and charcoal, and it is used to make reinforced tools that last considerably longer than standard ones. The mod also adds custom biomes for players to explore, including the eerie Dead Forest and the chilling Ice Caves.
Raranium is published for NeoForge only, for 1.21.4 – 1.21.8, and the latest file is 1.0.2 for 1.21.8. Every player and the server need a copy of the mod. The mod is released under All rights reserved and is not open source.
