I too have been searching for one, my friend I believe was the one to put the generators up! However he and myself have been unable to find any and I believe to closest to getting to the would to use the ID auto-fighter on AQ-Elite. Monsters such as these are very useful
796 - Vince's Gold = Quite a bit of Gold
919 - NightBane = Lot's of EXP
2960 - Dark Madder = Insane amount of Gold and EXP (I would advise using on an X-Guardian as the AQ team are hesitant to ban they're paying players)
