This guide explains how to dupe items with the world save and the character save.
How to Dupe Items
World Save Method
1. Copying the world file
To start, you first have to make a copy of the world file in which the itens that you want to dupe are.
World files are located in your appdata directory on the Worlds folder inside Valheim:
Tip: to go to the Appdata folder, Press your Windows key + R and type %appdata% on the box.
Your world saves will be listed as Data Base Files, like this:
Make an external folder and copy the world file you want to use to this new folder.
2. Grabbing the items
After saving the world file with the items inside it, open the world and grab the items that you want to dupe.
Log off the world with the items in your inventory. Then proceed to the external folder created and copy the old world file (the one with the items inside) from there to the worlds directory, overwriting the save (the one with no items)
When you go back to the world, the items that you took will be there again, completing the dupe.
Character Save Method
1. Grabbing the items and storing in your inventory
Grab the items that you want to dupe, store them in your inventory and log off.
2. Copying the character
With the items inside your inventory, create an external folder to store the character save.
Then go to the characters directory:
Copy the character save and paste it in the external folder.
With the equipped character save copyed, go back into your world and store the items back into a chest.
After storing the items into the world, log off, go to your external folder ang copy the old character save from there. After copying, go to the characters folder inside appdata and paste the old save there, ovewriting the one with no items.
After ovewriting the character save, log into your world and the items should be both in the chest and in your inventory.
