01:43 You see a fusion rod.
It can only be wielded properly by druids of level 100 or higher.
It weighs 38.00 oz.
Bought by Magrao [ID:6].





All items purchased at the shop comes with an ID and name of the character, so it's easy to remove cloned items!

Cool, but this description should be hidden.
I'd rather prefer:
http://otland.net/f81/basic-anti-dupe-system-131898/
and simply adding:

doItemSetAttribute(uid, "serial", generateSerial())

to this file.

Anti dupe system is better cuz players can't see ids and there is unique serial code for every item.
