Just go to the Giant Pit that is in the middle of the map and go to the higher of the 2 roadblocks. Go into forge mode and look straight ahead. You should see a giant pane that has one bolded line and some little lines to the left and right of it. Look to the right and up and go all the way up to the top and you will find it. The video is easier to watch and listen to and it explains how to grab it once you found it.
