Macelib
Macelib is a specialized library mod designed for modification developers. Its main function is to provide tools for creating custom spells and enchantments for the mace, which was added in Minecraft version 1.21. Additionally, the library allows developers to add completely new types of maces to the game.
It's important to note that when installed alone, this mod doesn't add any new game content. The only thing it does is allow the standard mace to interact with existing durability and combat characteristic enchantments.
Additional information for developers interested in integrating Macelib into their projects can be found in the documentation.
