the easiest way im doing this quest is i have a lvl 70 archer and since i go to map 1 of Holloween quest its so easy to kill the DarkLord

, this way iv gotten prety much 70+ mets with him alone and i still concider my archer a noob

and for useing the hide function its d/c but heres a tip u might wana try.
1) Stay still where u are when useing the hide function and wait till u see the players pop back to ur screene
2) move somewhere else and wait til u see monsters or other things pop up and go back to ur original position happy hunting
