Alex's Caves rad fork

The fork is based on Alex's Caves and changes radiation and acid protection so it is defined through a tag. Cave biomes are rare compared with ordinary biomes, yet each one carries its own variety of blocks, items, mobs and mechanics, which makes them considerable underground destinations. The six biomes are Magnetic Caves, Primordial Caves, Toxic Caves, Abyssal Chasm, Forlorn Hollows and Candy Cavity. Players find them by locating cave biomes, and an Underground Cabin can be found anywhere in the overworld to start that search.

Cave tablets and a Cave Compendium guide book are found in loot barrels and explain what is needed to find and explore each biome. Every biome has its own ambient particles, fog, brightness and light color. The author recommends playing without shaders, since many shaders alter the unique appearance of several biomes. The mod has built-in compatibility with Enough Items.

The fork is open source under the GNU Lesser General Public License v3.0 only. It is published for Forge and NeoForge, with files for 1.20.1 dated 2025-01-29, and it runs on client and server. Citadel is required, and Alex's Caves is listed as incompatible, so the two cannot be installed together. The fork is a separate project from the original mod.
