oSzoukaua's: Book o' Experience
This mod offers a unique solution for storing and managing experience in Minecraft. It adds a special book to the game that can be crafted and used to save accumulated experience levels with subsequent retrieval.
Main Features
The key feature of the modification is the experience book, capable of storing from 0 to 30 levels. This allows players to safely save their progress without worrying about losing valuable experience while exploring dangerous areas or participating in challenging battles.

Technical Features
The mod works exclusively on the server side, meaning it needs to be installed either in a singleplayer world or directly on the server.
Important Notes
Due to calculation specifics in the game's code, there's a minimal chance of losing an insignificant amount of experience points during save and retrieve operations from the book. However, this margin of error is so small that it practically doesn't affect gameplay.
Compatibility and Usage
The modification can be freely used in modpacks, YouTube videos, and other content distribution formats.
