There is a simple way to beat this quest......The only things you need are:1) Must be lv105 n
2) A mage or Paladin
This is how you finish the quest fast.
You have to kill 3 or 4 skeletons then wait or you can just focus on one skeleton.....this will not allow the maze guardian to spawn(The big Blue Mob).

If you guys got any questions feel free to ask.
