I remember a port exploit, you could basically dupe items or give them mental stats.
I can't remember it 100%, but you would basically run a server on your local machine, the DBServer (Maybe?) would point to the IP of the live server, create an item using GM Commands - Lets say Wooden Sword dc+255 luck+10
It would then somehow transfer that item over to the live server.
God knows how, but I'm sure I did not makethis up!
That is an interesting one. I know there are methods of duplication but I cannot recall knowing any way to do it. If that way worked then that is hilarious and also concerning.
