Overleveled

Overleveled is a Fabric server-side mod that opens up new possibilities for working with enchanted books. With it, you can apply enchantments to tools and weapons that exceed Minecraft's standard limits.

Imagine this scenario: you have an Efficiency VI enchanted book and a regular pickaxe. Thanks to this mod, you can combine them on an anvil and get a pickaxe with Efficiency VI, which is impossible in the vanilla version of the game.

It's important to note that the mod doesn't remove the basic limitations of the enchantment system. If you try to combine a pickaxe with Efficiency V and a book with the same enchantment, the result will remain the same - a pickaxe with Efficiency V.

This solution is particularly useful for servers and modpacks where players can obtain books with enhanced enchantments that go beyond the standard system. The mod has been tested on versions 1.18.2 and 1.20.4, but should work in any edition of Minecraft.
