Raranium
A mod that introduces new ores, biomes, and features while remaining vanilla-friendly.
About this Mod
New Ores and Materials
This mod introduces significant new content to enhance gameplay. A key addition is Raranium, a very powerful and rare ore that generates exclusively within Raranium veins found beneath hot biomes. This ore can be used to craft tools and armor that offer superior performance.
Another new material is Darkstone, a common ore found widely in large veins. When smelted, Darkstone yields Lightstone, an incredibly versatile material for building. Lightstone can be transformed into various decorative and functional items such as doors, bricks, trapdoors, and fences. It also serves as a material for crafting Lightstone tools and armor.
Furthermore, Steel is introduced as a new material, created by combining iron and charcoal. Steel is essential for making reinforced tools that are considerably more durable than standard ones.
The mod also expands the game world with several new custom biomes for players to explore. These include the eerie Dead Forest, the chilling Ice Caves, and The Reg, each offering unique environments.
