KoHs Offhand Whitelist
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.
KoHs Offhand Whitelist
KoHs Offhand Whitelist is a client-side Fabric mod that controls which items you can move into the offhand slot.
Instead of allowing every item, the mod uses a whitelist.
If an item is not allowed, the mod blocks offhand insertion/swap actions for that item.
What this mod does
- Blocks non-whitelisted items from being placed in offhand
- Allows editing the whitelist from an in-game GUI
- Shows all Minecraft items (including potion variants) with search
- Lets you quickly add/remove items with
+and- - Supports presets (built-in + custom)
- Auto-saves changes instantly (no manual save needed)
GUI Tabs
- Whitelist: manage allowed and non-allowed items
- Create Preset: build/edit a preset from selected items
- Custom Presets: use, edit, or delete saved presets
- Report Issues: support/help section with Discord button
Why use it
Useful for PvP and utility clients when you want strict offhand control (for example only totem, shield, crystals, specific potions, etc.).
