People saying they got it working on Official Leaked Files too - i dont know!
You simply need a GM Shop, double click ANY stackable item - as SoulShots/Arrows, do NOT click anything else now. a window will pop up with the amount to enter.
now, click the GM shop again, click on the desired weapon category (i.e. Swords - Sowrd of Miracles * Acumen).
click ONCE on the sword you want. BE CAREFUL TO NOT CLICK ANOTHER WEAPON NOW!
enter the amount of swords in the window that popped up before as you clicked on the arrows.
enter 20 and click buy.
done.
you got 1 weapon in your inventory, but in fact you bought 20.
now get enough enchant scrolls and start enchanting.
as soon as a weapon brakes, you will still haev the other 19 in your inventory on the LAST enchant level that succeeded.
so, if you enchant 1,2,3,4,5,6 brake - the other 19 weapons will still be at +6 enchant.
if you figure any problems, feel free to ask
edit: it also works with L2Walker, just tho with walker you have a chance to get directly banned if you dont have to correct protocol ID and so on
