1. find a noob with d grade ~
2.lets say he has d gr bow.and say to him do u want to have 2 bows?he says yes.
3.then invite him to a party(it has to be random) say to him to drop his bow o the ground and when he picks it up to do a restart :)
4.when he piks up the bow u may get or he but if u get it dont return it to him :D
It worked on l2 beyond long time ago... but u have to find a noob becouse if u ask a gr~ to do it he wont. lots of people know this trick
