Invisible wall. When you are above the place where you drop down to the hole for the last fight. just hug the wall to the left. Climp up the the edge. Now pretend that the wall continues where it ends at and take a jumping leap of faith. You will land on a place in the air. Continue jumping forward and you can keep climbing INVISIBLE steps. Be careful it only goes up 10 or so steps and the fall is quite painful. Thought someone could have some fun with this..
