Oh, you don't have to do that quest. It's optional now, I completely skipped it, because it lacked a good amount of exp and it was extremely hard, because the bosses cheats. Besides i'm a solo player. :3
hey can someone help me with this task its rly hard and the boss cheats
Did you know that quest is no longer "required"?
