Crimson is a mod for Fabric 1.15 which adds crimson biome pockets scattered throughout the world which are linked to a system of crystal magic.
These crimson biomes have dense red fog and blood red water, and come in four variants: Crimson Forest, Crimson Marshland, Crimson Brushland, and Crimson River. The choice of biome is based on what biome would otherwise generate there.
The mod also adds new ores, which link to the infused crystal magic system: combine crimson essence with a gemstone to infuse the gemstone, then use a Magic Device Crafter to make a magic device out of the infused gemstones! Each gemstone adds its own unique properties to the device and its function. Each gemstone added to the device also can have up to two modifier gemstones used on it.
Recipes can be found with a mod such as REI, though here are some of the most important recipes for reference:
