Zonne's Duplication

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 NeoForge only.

Minecraft 26.1–26.1.2Newest
Minecraft 1.21.4–1.21.8

⬇ Download for 26.1–26.1.2 ⬇ Download for 1.21.4–1.21.8

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.

Zonne's Duplication Mod

This mod adds a simple highly configurable duplication command working with cheats disabled.

Features:

/dupe (amount*dupeamount)
/megadupe (amount^dupeamount)
/d and /md (Shortened variants of the commands above)

The configuration file allows setting a duplication limit to both commands individually, setting command error messages, and allows disabling any of the 4 added commands.

There is also an option to have duplicating cost XP levels or points, and one to disable bottle of enchanting duplication.

The mod also includes a helpful unstackable item fix making megadupe function like normal dupe with unstackable items (can be disabled in config)

Zonnes Duplication was tested on 1.21.4 and 1.21.8, but works on any version inbetween. Also works on 26.1.X
