How do I install Tool Scaling?

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 Tool Scaling work with?

The listing gives Minecraft 1.21.1, 1.21.2, 1.21.3, 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 NeoForge1 build
Mod loader Forge1 build

Minecraft version

Minecraft 1.21.1–1.21.11Newest

Minecraft 1.20.1–1.20.6Newest

⬇ Download for 1.21.1–1.21.11 · NeoForge ⬇ Download for 1.20.1–1.20.6 · Forge

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.

Tool Scaling

A Minecraft Forge mod that adds anvil-based tool upgrading with durability and enchantment preservation.

Features

Anvil Tool Upgrades: Upgrade tools in the anvil instead of crafting new ones
Durability Transfer: Preserve tool durability when upgrading (percentage-based by default)
Data Preservation: Keeps enchantments, custom names, lore, and all NBT data
Extensible Recipe System: Other mods and datapacks can easily add their own upgrade recipes

How to Use

Place your tool in the left slot of an anvil
Place the upgrade material in the right slot (e.g., diamond for iron → diamond)
Take your upgraded tool with all enchantments and durability preserved!

Available Upgrades

Normal Tier Progression (1 material, 1 level):

Wooden → Stone (cobblestone, blackstone, etc.)
Stone → Iron (iron ingot)
Iron → Golden (gold ingot)
Golden → Diamond (diamond)

Special Shortcuts (1 material, 3 levels):

Iron → Diamond (diamond)

Note: Diamond → Netherite upgrades use the vanilla smithing table with netherite upgrade template.
