Terraria – How to Duplicate Any Item (Journey’s End / Update 1.4)

This guide will tell you how to duplicate any item of your choosing in Terraria 1.4+. I recommend not doing this excessively as it can ruin the Terraria experience.

Simple Duplication Item Guide


Make sure to turn Off the AutoSave feature in settings.


  1. Get items you want to duplicate and leave them in your inventory.
  2. Save and Exit out of your world.
  3. Click Multiplayer.
  4. Click Host & Play.
  5. Start up a local server.
  6. Once in the world put the items you want duplicated in a chest and close out of the chest menu.
  7. Press ALT + F4.
  8. Load up your world in Singleplayer.
  9. Your items have been duplicated.

Video Guide

Here is a video guide on how to do this as well:


  1. i accidentaly did this with the arkhalis on xbox and the arkhalis is the rarest item in the game,1 in 40 million chance of acquiring

  2. This glitch has been around for ages, also there’s Journey with changing game style to any other like master mode, Journey mode was implemented so you didn’t have to do this kind of thing XD

  3. Doesn’t the item frame + workbench dupe trick work? It also only works on a hosted multiplayer game.

  4. i have 100+ hours and i find this really helpfull,
    mainly for the new update i was stuck becuse all the charecters left
    before i could do anything
