EnchantmentSlots
A lightweight, packet-based, and highly configurable enchantment slot framework for modern Minecraft servers.

EnchantmentSlots is an advanced enchantment slot control plugin for Spigot/Paper servers.
It is built for servers that need clean item data, strong compatibility, custom slot logic, and full control over enchanting limits.
