About DupeChest (Duplication Chest/Dupe Chest)
From ModrinthThis mod adds a chest that duplicates/mirror the contents of your inventory. Infinite resources await, but only for those who conquer the end-game.
📦 DupeChest
DupeChest is a high-tier expansion that introduces the ultimate reality-bending utility to your Minecraft world. Rewriting the laws of the matrix, this mod allows you to duplicate your most precious items—at a legendary cost.
🌌 What's in the Mod
The mod centers around the Dupe Chest, a custom block entity designed for end-game progression:
- The Dupe Chest: A unique storage block that duplicates items placed within it.
- Short on resources? Missing that one piece of Redstone for a torch? Just dupe it!
- Left your stash behind? Forgot your 67 stacks of Emerald Blocks at home? Don't worry, just dupe 'em!
- NBT Support: It copies everything, including items with NBT data—meaning you can clone fully Enchanted Books and even entire Shulker Boxes!
🛠️ Crafting & Progression
To prevent world-breaking imbalances, the Dupe Chest requires a massive 9-item shapeless recipe consisting of the rarest artifacts in the game:
- Ingredients: Dragon Egg, Dragon Head, Mace, Silence Armor Trim, Music Disc (Pigstep), Conduit, Creeper Head, Piglin Head, and an Enchanted Golden Apple.
- Recipe Book: As soon as you obtain a Dragon Egg, the recipe will automatically unlock in your green recipe book.
🚀 Getting Started
To begin your journey into the matrix, you must defeat the strongest bosses and raid the deepest structures to gather the 9 required components. Once crafted, place the chest and witness the laws of reality rewrite themselves.
