easy....
edit your server side and client side
edit your item_DB and then make your items
EX.for item_db
8000 busterblade,busterblade o 10909 9299 4498 398 09 98289 {**,{** ;
(dont use this its only an example)
then for client side
idnum2itemdesctable
idnum2itemresnametable
idnum2itemdisplaynametable
num2itemdesctable
num2itemdisplaynametable
num2itemresnametable
and itemslotcount
edit these to amke your item in client side
to make an items description you need to encrypt the text in code to make it apeear in english not jiberish
have fun... im not telling you how to edit
