The process of research and duplication is fairly straightforward in Terraria. To duplicate items in Journey mode you must first gather enough of the item you wish to duplicate so you can complete its research. Both of these options can be found under the Power Menu on the inventory screen. To make the process clearer here’s an example for you:

  • Find/Build 100 Torches.
  • Place Torches in Research (requires 100).
  • Research Torches.
  • Once fully Researched can be duplicated via Duplication.
  • When duplicated you receive full stack of items.

The above process requires collecting the items you wish to duplicate so you can fully research them. This means finding items, harvesting items, etc. When you do research you will lose the stack you submit so be warned. Ideally wait until you have a full stack to submit.
