How to Use the Duplication Menu in Terraria
The duplication menu in Terraria is super easy to use once you get the hang of it! First, you gotta make sure you're playing in Journey mode since that's the only mode where it's available. Then, open your inventory and click on the power menu on the right. You'll find the duplication menu there. Just select the item you want to duplicate, provided you've researched enough of that item (usually 100 of common items or 1 for weapons and armor), and voila! Duplicate away and never run outta resources again.

To use the duplication menu, just play in Journey mode. No research, no dupes. Keep it simple.
Honestly, just gather lots of what you wanna duplicate early on. Makes the whole process a breeze later.
