How do you dupe?

[Haku]

Was always confused about that...
What even is duping?
Saw it in a thread for furniture?

Duping is an online exploit where you can create copies of items. But don't do that. It's not just cheating, but it's also breaking the game.

It's okay to dupe, but duped items cannot be traded here. The site frowns upon that.
