⬇ Download on ModrinthPowerItems is a sophisticated yet lightweight Minecraft plugin designed for 1.21.x servers that allows administrators to bind dynamic potion effects directly to items. By leveraging modern Java 21 architecture and the PersistentDataContainer (PDC) system, this plugin ensures that all custom abilities remain permanently attached to items regardless of name or lore changes. The core feature allows for precise hand-specific activation, meaning you can configure an item to grant Speed when held in the Left Hand, Strength in the Right Hand, or both simultaneously. With a fully customizable config.yml, you have total control over all messages, visual lore, and effect intervals to perfectly match your server’s theme. Whether you are running a competitive Survival world or a complex RPG network, PowerItems offers an optimized and seamless way to introduce unique gameplay mechanics without compromising server performance.
