Hi, Ok, I am not sure if this exploits works, but I've heard of it before, I tried it on L2 revenge, it in fact, half work, but its useless, let me explain :
In a server with a GMSHOP, open the shop that sells for example SS
Now DOUBLE-CLICK on any type of SS
Now the amount window pop-up
Now just let this window open and open the Weapon Shop.
Do a SINGLE-CLICK on the weapon you want to enchant.
* Meanwhile the processus, click on the amount window to keep it "active" so it doesnt close. *
Now that the weapon you want to enchant is selected by one click, it should have a pale blue border on it.
Now.. just enter an amount like 30
The price should appear, the regular price, there is no bug on this, so if you are buying a 20kk weapon, it will be 20kk x 30, so try it at first with cheap gears...
Usually, before you hit buy, you should see only one item in the buy window, i mean, the price will be 20kk x 30, but you should only see one item
Now, crucial time, hit buy, if you find 30 weapons in your inventory, it means it doesnt work, like on revenge, you can still upgrade them one by one and obtain a lucky ++ weapon which you could re-sale.
If the exploit work on your server, you should have only one weapon in your inventory, but that is in fact, 30 weapons stacked one over each other.
If it works, start upgrading it, if the scroll fail and the weapon "break", it means you have lost one of your 30 stacked weapons, but the ++ stays !, so, its like if you had 30 chances to break you weapons, and everytime that the weapon break, you keep the enchant on.
Thats it, to tell the truth, i never go it working, but I've heard that ppl go it to work...
So... thats it, Enjoy
If you guys could tell me if it works on your server, i would be happy, thx !
