Mate you are doing the enchant trick wrong. You need to log a female human dagger(race/gender can't be changed) preferably on 2nd class. Then go to gludio castle messenger, stay behind him for 10 seconds. Equip a dagger that you like. Drop the weapon that you want to enchant 2/4/6/8 times(number of times must be even, not odd). Pick it up again and again. Then go to his face and backstab him 4 times in the face. Those facestabs trigger the ncsoft newbie assistance algorithm and it improves your random number generator rolls. Right after the 4th facestab you need to write "I love Koll and innova sucks" on All chat(IT HAS TO BE ON ALL CHAT, OTHER CHATS AREN'T RECOGNIZED BY THE ALGORITHM) then equip the weapon you want to enchant, right click the enchant scroll, drag the weapon to the open slot and press enchant.
It's kinda tricky but you have to do it to achieve 99% enchant rate. Good luck.
