Before the stairs leading to the Boss Are some cracks in the wall which you can ram through. Use the whirlwind, and then the next one, to reach the high tower. From here, look ahead and you will see a tall platform in the distance, outside and to the left of the outer wall of the main yard. Glide to it and get the Orb.

Another description to get this Orb is as follows: climb up all the ladders next to Moneybags. Turn left at the portal to Scorch. Go down the hallway until you find a cracked wall on your left. Break the wall by charging into it. Go up the whirlwind. At the top of it, you will find a few gems. Then, go up the other whirlwind. Glide from the platform to the long green platform. There should be an Orb at that location.

From the tall platform (above), glide the outer wall and make your way to the left. At the end you should see another cracked wall. The Orb is inside.
