Minecraft is, at its core, a survival game. This makes obtaining items and materials the most important part of the game for players. However, there are still multiple methods in the game as of 1.191.1 that allow players to duplicate their items, reducing the grind in single and multiplayer setups.
While Mojang has patched dozens, if not more, of item duplication methods over the game’s decade, the community has been amazing at discovering new item duplication methods.
Minecraft 1.19.1 has several duplication bugs
These bugs and glitches rely on flaws within the game code to operate. This means that they can be patched at any time, with little notice from Mojang. Additionally, there may be strange occurrences or even game-breaking outcomes, so players should proceed at their own risk.
Also, the mirroring flaws below are only tested on the Java edition of 1.19.1 and are therefore not guaranteed to work for Bedrock.
5) String duplication
A rope is a pretty basic item. Players can use it to make things like bows, fishing rods, and wool or trade it with villagers for access to emeralds. This means that the duplicate chain can give players unlimited access to emeralds.
This method is also easy. Players must make a small channel of water leading to a perpendicular area five blocks long, with a trap hook at each end and three ropes in the middle. When water is put in, flowing, and breaking the thread, four threads will fall, one more than the one that was put in.
4) Tripwire duplication
Tripwire hooks are in a very similar location to the rope. These are items with limited uses, such as making chests with traps and crossbows and selling them to villagers for emeralds. Like a rope, tripwire hooks are easy to double reliably.
Players must place two trapdoors on the edges of the blocks closest to each other, three blocks apart. Players then have to crouch down and place a hook on each hatch, connecting them with a rope.
When players walk on the rope, the rope and the two trap hooks will drop, although only one of the hooks breaks. This means that players can turn two tripwire hooks into an infinite number of them.
3) Villager Trading Duplication
As powerful as villager trading is as a whole, there is one incredibly frustrating aspect, meant to balance the power of the system: the fact that villagers run out of stock, meaning players can only do so much trade. so many times in a short period.
However, a multiplayer method will allow infinite villager trading. If a player is in a boat with a villager in the second seat, another player can open the villager exchange interface and the player in the boat can log out of the server. This will make the boat and the villager disappear as well. The remaining player can trade until the stock runs out.
Once the stock is depleted, the ship player can rejoin. This will also cause the ship and villager to respawn, with all their trades in stock. Players can do this as much as they like to avoid losing trades.
2) Ship Chest Duplication
This dupe is another dupe that requires a second person. However, unlike the cheat above, it will require a second person instead of an alternate account.
The first player must enter the chest boat and prepare to exit Minecraft. The second person needs to enter the chest interface and start quickly placing and removing the chest.
The boat player must then exit Minecraft. This will sometimes result in the item being duplicated, which will end up in the chest and in the player’s inventory.
1) Shulker Duplication
This is a difficult method to achieve outside of mods. However, it is also simple. If a player removes an item from a shulker box at the same time in the game that they close the shulker interface or if the shulker is broken, the server cannot record that the shulker has lost the item. However, you can record that the player has won the item.
Players can use mods to guarantee this effect or try and time it with a friend on a server to duplicate all the items inside the shulker box.
