Alex's Caves rad fork

Fork of Alex's Caves to allow tags for radiation and acid protection.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Mod loader Forge1 build
Mod loader NeoForge1 build

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This is a fork of Alex's Caves with the radiation and acid protection set to use tags instead of item ids. This item will be archived once the capability is added to upstream Alex's Caves. Please support the original creators instead of me.

Currently adds:

Radiaction protection item tag, "rad_protective_armor".
Acid protection item tag, "acid_protective_armor".
Radioactive items with the following item tags:
- weak_radioactive_items
- radioactive_items
- strong_radioactive_items

All of these use the ModID "alexscaves".
