Crimson
The Crimson modification for Fabric 1.15 introduces players to unique crimson biomes that can be discovered in various corners of the world. These mysterious zones are connected to a special system of crystal magic.
Crimson biomes are characterized by dense red fog and blood-red water. There are four varieties of such zones: Crimson Forest, Crimson Marshland, Crimson Brushland, and Crimson River. The type of biome that forms depends on the original landscape of the area.
The mod adds new ores that serve as the foundation for the system of enchanted crystals. To create magical devices, you need to combine crimson essence with gemstones to imbue them with magical properties, and then use a special crafting table to create magical instruments.
Each type of gemstone gives the device unique characteristics and functional capabilities. Additionally, up to two modifying crystals can be added to each main gemstone to enhance effects.
Crafting recipes can be studied using mods like REI, but here are some key schematics for reference:
