ITEM UPGRADER

Item Upgrader brings a CS-style item upgrading system directly into Minecraft. Risk your existing blocks and items for a chance to receive a more valuable reward through a polished, animated interface.

No real money, external websites, accounts, or purchases are involved. Everything happens entirely inside Minecraft.

Features

• Place up to 64 items in a single bet.

• Combine different item types across nine bet slots.

• Quickly select a target using the x1–x10 multiplier buttons.

• Search the full supported item catalog without an x10 limit.

• View the exact bet value, target value, multiplier, and success chance.

• Watch a circular CS-style roulette animation for every upgrade.

• Choose from 16 interface color themes using Minecraft dyes.

• Dyes placed in the theme slot are not consumed.

• English and Russian language support.

• Works in both singleplayer and multiplayer.

How It Works

Open the upgrader with:

/upgrader

Place your items into the bet slots and choose the item you want to receive. The success chance is calculated from the value of your bet compared to the value of the selected target.

For example:

• A 2V bet for a 3V target gives approximately a 66.67% chance.

• An x2 upgrade gives approximately a 50% chance.

• An x5 upgrade gives approximately a 20% chance.

• An x10 upgrade gives approximately a 10% chance.

If the upgrade succeeds, you receive the selected target item. If it fails, the entire bet is lost.

Supported Items

The built-in catalog supports 1,388 safe vanilla blocks and items in their default state. Technical items, operator-only blocks, spawn eggs, and items requiring unique stored data are excluded to protect gameplay balance and prevent exploits.

Security

All important calculations and upgrade rolls are verified by the server. The client cannot change item values, success chances, targets, or roll results.

Requirements

• Minecraft Java Edition 1.21.11

• Fabric Loader 0.19.3 or newer

• Fabric API

• Java 21

The mod and Fabric API must be installed on both the server and the client when playing multiplayer.
