Which creature do you have to fight in adventure quest worlds to get the unidentified weapon

Easy, you need to beat the 12 Lord Of Caos, after 4 or 5 times then you will probably get it. I don't garanty that you will have the weapon that you want because their are a lot of them (weaponsand other stuff). Some of them are for member but those who arent, are still good. So... you should beat all Lords Of Caos until you get to number 12! if you want that weapon!
