How do I install Mob Duplicate?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does Mob Duplicate work with?

The listing gives Minecraft 1.20, 1.20.1, 1.20.2, among others. This is the version stated by the author or source site, not something we verified ourselves.

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 Paper1 build
Mod loader Purpur1 build

Minecraft version

Minecraft 1.20–26.2Newest

Minecraft 1.21–1.21.11Newest

⬇ Download for 1.20–26.2 · Paper ⬇ Download for 1.21–1.21.11 · Purpur

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.
