XP Tome Add-on 1.21+

Tired of constantly losing your experience levels due to accidental jumps in the Nether in Minecraft? The mod XP Tome allows you to safely store your accumulated levels in a special book and use them at any time without the risk of losing them.

The book supports storing up to 30 levels, which is perfect for enchanting and upgrades, and visual effects make the process simple and clear: the item begins to glow, and the name changes when it is filled.
