XP Bank — Experience Storage for Minecraft
This datapack/mod offers players an innovative solution for storing accumulated experience points in regular glass bottles, transforming them into convenient containers for future use.

How the System Works
Experience Conversion to Bottles: To convert experience into bottles, approach an enchanting table while holding empty glass bottles and use the Shift + click combination. Each filled bottle will contain one full experience level.

Storage and Usage: Created experience bottles can be safely stored in chests and used at any time. To restore the saved experience points, simply right-click the bottle in your inventory.
Balancing and Limitations
Certain restrictions on the amount of stored experience are implemented to prevent potential system abuse. The minimum cost for filling one bottle is one experience level.
This project is perfect for players who value every accumulated level and want to protect their experience from loss due to character death.
