First of all, If your a paladin, go away, its too easy for you.
Mount, fly, jump, bubble.
Annnnyway back to the point,
this is how to do the Going Down achivement, 65 yards without dying.
Just go to the Scryer lift and follow these pictures.

Now, once your at the edge of the platform, press forward and jump,
this should get the achivement and JUST stop you dying.
