Modded Item Upgrader

Modded Item Upgrader turns spare Minecraft items into a tense, easy-to-understand upgrade game. Choose an item to risk, select the reward you want, set the quantity, and spin the upgrade wheel. Win and the upgraded items are delivered to you; lose and your stake is consumed.

HOW IT WORKS
1. Open the Upgrader screen from your inventory.
2. Pick the item and quantity you want to risk.
3. Choose a reward from the searchable item catalog.
4. Review the calculated success chance and start the upgrade.
5. Receive the reward after the roll succeeds.

KEY FEATURES
• Inventory-based upgrade wheel with a clean visual interface
• Searchable item catalog and detailed item information
• Recipe-aware item values for more sensible risk and reward calculations
• Configurable quantities and a maximum success chance of 95%
• Server-side validation to prevent invalid or manipulated upgrades
• Persistent delayed rewards, so completed rewards survive restarts
• Datapack audit tools for balancing custom recipes and modded items
• Designed for both single-player and multiplayer servers

LANGUAGES IN 0.6.5
The interface follows the language selected in Minecraft.
