About

A Fabric *.21.11 utility mod that lets players duplicate the item held in their off-hand by typing .dupe in chat. The duplicated item (with full data components: enchantments, durability, custom names, lore, etc.) is placed into an existing matching stack or the first empty inventory slot. Sends color-coded feedback: green on success, yellow if off-hand is empty, red if inventory is full. No server-side interaction required.
