Well, i gave it a try in an l2j int server... Firstly i changed the row of the packets so...
1) use item
2) enchant item 3) deposit item
4) deposit item
But... If it fails i get the crystals and a fake item in my wh, so i keep on enchanting that way(fake item).finaly i get on an x enchant...if i want to trade it , i just cant and if i rr the fake item disappears
Any clue?
