AdvancedDupe is a feature-rich item duplication plugin for Minecraft servers. Players can duplicate items in their hand using the /dupe command with customizable permission-based limits. The plugin includes a comprehensive blacklist system that blocks items by material type, display name, or lore. It features intelligent container checking that scans shulker boxes and bundles recursively to prevent duplication of restricted items. Additional features include a cooldown system to prevent spam, world-based restrictions, and full message customization. Perfect for creative servers, testing environments, or special game modes requiring item duplication.
