Forum:How do you dupe a weapon or shield???

Have been following this wiki for many months. Keep seeing "will dupe" this or that. How is this done? I play on PS3 but not online. Saw a post about duping a weapon in Madd Moxie's. How do you dupe a weapon? Thanks for help (in advance). You WILL die....I know...I did. 14:38, December 7, 2010 (UTC)
