LOL, i made over 150k fa in 3 days with some bugs, however can't login to l2inc. They say that i didn't get ip banned, but however i can't login to desperion. I made server to lag by using bugs to create FA, and i believe that there are lots of people doing the same, that's why server lags so much.
It sure works on very big servers. But on other hand, it's like normal enchanting, just a chance that u'll be lucky to do this right and get that ,,safe enchant". I'm still trying to master this technique, but it's kinda hard :/
