Item duplication is a vulnerability present in almost all modpacks. Allowing the use of item duplication to complete a modpack offers a gameplay style distinct from normal playthroughs. However, many item duplication glitches require a large amount of repetitive operations, reducing the game's enjoyment. This data pack provides several easy methods for simulating item duplication glitches:

• Any version: if the player looks down and throws an item, the item count will become 64.
• Minecraft 1.17 and newer: the quantity of items in your off-hand will automatically be the quantity of one stack (e.g., snowballs will become 16).
• Minecraft 1.17 to 1.20.4: When sneaking, the number of items in your off-hand will automatically become 64.

In addition, to balance the game's difficulty, a "killer" system has been added: when you try to open a loot chest, a large number of "killers" will try to stop you. Killing the "killers" will allow you to obtain the loot inside the chest.

The killer is extremely dangerous: the killer can also "duplicate". If you don't confine the killer to a closed space, allowing it to "duplicate" uncontrollably and relentlessly, it will take over the entire world. If there are no weapons of mass destruction, the only solution is to use the /kill @e command.
