Illicit Blocks

by cargocat · on Modrinth

Adds in missing block items for blocks, and block states for said blocks. Free Minecraft Java mod for 24w09a, 24w10a, 24w11a.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21.5–1.21.8Newest
Minecraft 1.20.1–1.20.4

⬇ Download for 1.21.5–1.21.8 ⬇ Download for 1.20.1–1.20.4

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.
