Minecraft is, at its core, a survival game. This makes getting items and materials the most important part of the game for players. However, multiple methods still exist in the game as of 1.191.1 allow players to duplicate their items, cutting down on the grind in single-player and multiplayer settings.
While Mojang has patched dozens, if not more, methods for duplicating items over the decade that the game has been out, the community has been incredible at figuring out new methods to dupe items.
Minecraft 1.19.1 has a number of duplication glitches
Disclaimer
These bugs and glitches rely on faults within the game’s code to operate. This means they can be patched out at any time, with little notice from Mojang. Additionally, there can be strange occurrences or even game-breaking results, so players should continue at their own risk.
Additionally, the duplication glitches found below are only tested on the Java edition of 1.19.1 and are therefore not guaranteed to work for Bedrock.
5) String duplication
This dupe is another dupe that requires a second person. Unlike the previous dupe, however, it will require a second person instead of an alternate account.
The first player must enter the chest boat and get ready to quit Minecraft. The second person needs to enter the chest interface and begin rapidly placing and removing the chest.
Then the boat player needs to exit Minecraft. This will sometimes result in duplicating the item, ending up in the chest and the player’s inventory.
1) Shulker duplication
This is a difficult method to pull off outside of mods. However, it is also straightforward. If a player removes an item from a shulker box on the same in-game tick that they close the shulker’s interface or the shulker is broken, the server cannot register that the shulker has lost the item. However, it can register that the player has gained the item.
Players can use mods to guarantee this effect or try and time it with a friend on a server to duplicate all of the items within the shulker box.
