Few ways to dupe.. : KO Submissions

1) teleport bug
u need 2 chars for duping...best is colony zone..
u /save ur char and trade item what u want dupe to ur other char
after then go to tp to moradon..if u are lucky..u can get lag..in lag u use all..mirror healing..pots..swift..wolf..etc..all if u are lucky u can get rollback

2) Spam town bug
stay next to entrace to arena../save char and trade items to ur 2nd char
after then greately spam town in command ...u get dc and if u are lucky u get rollback

3) very easy tactic..and 100%
when admins close colony zone or elmorad castle..give your items to bank
after /save and go to portal..game say u failled logging to curently zone
and u quit ko..run again ko and log other char in blocked acc
after then put items from bank and give to other char..every relog u have again items in ur bank..u can dupe 999999x all
~thanks for your time

Spam Bug and TP bug doesn't work

There is a confirmed trade dupe mthod, but its a little different,
and its not 100%.

all duped better be done in laggy times, like wars for better success rate.
