Hello every1, i try to explain one bug. I don't know but i think this is enchant bug. Ok first you need wepon what u want enchant and some ewx , also u need two chars. With one char u have wepon and enchants , another char will be clear. Now press on enchant double click and chose your wepon , then target your second char and /trade . Add your wepon to trade and press ok but with another char don't press ok just leave it. Now press ok in enchant table , if your wepon broke press ok with another char and your char will get the item don't broken. Ofcourse ewx will disapeared but u will not broke the wepon.
I think u will get the idea.
I try in some l2j servers and works.
Sorry 4 bad english.
