Minecraft Java 1.16.5 Multiplayer Any Item Dupe Glitch (Working on Realms)

Storyline / Context

This video demonstrates a new item duplication glitch (dupe) in Minecraft Java Edition 1.16.5 that works on vanilla multiplayer servers, including Realms. The glitch requires no server modifications such as Paper or Spigot and was discovered by a YouTuber named Veternato.

Gameplay Highlights & Glitch Explanation

The glitch revolves around using an Elytra combined with special firework rockets that deal damage upon use (approximately 3.5 hearts). Key points include:

The player must have less than 3.5 hearts of health before activating the firework rocket.
When the firework rocket is ignited while gliding with the Elytra, the player takes damage as part of a scripted event.
The crucial step is to disconnect from the server immediately after igniting the firework but before the damage is registered and the player dies.
Upon disconnecting, the player’s inventory remains intact even though the game registers the player as dead and drops their items on the ground.
Logging back in shows the player retaining all original items plus the dropped items still on the ground, effectively duplicating the items.
This method can be repeated indefinitely to multiply any items, including shulker boxes filled with valuable blocks like diamond blocks.

Step-by-Step Guide to the Dupe

Ensure you are in a generated chunk area (no need for a friend to generate chunks).
Use an alternate account equipped with Elytra and firework rockets that deal damage.
Reduce your health below 3.5 hearts (self-punching works).
Equip shulker boxes filled with the items you want to duplicate.
Fly using Elytra and ignite the damaging firework rocket.
Immediately disconnect from the server before the damage kills you.
Log back in to find your inventory intact and the dropped items still on the ground.
Collect the duplicated items.
Repeat as desired.

Key Tips

The glitch works on vanilla servers and Realms.
Firework rockets must be the damaging type, not normal ones.
Timing the disconnect is crucial—disconnect before the damage event kills the player.
No need for a friend to generate chunks; any already generated chunk area suffices.
The glitch is reliable and can be repeated multiple times.
