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.
