Basically you need to have a partner with you to make it easier. You can just Elusive Jump all the way, but the positioning and angle are pretty strict. You start off on top of that stand where you trade in tomestones. You then sprint and jump off the roof towards the back side and AM
(Aetherial Manipulation) or EJ
(Elusive Jump) onto those thingies that look like a platform(?).
((Sorry, I don't have a better picture.))
After you get there, jump to the platform on the wall behind you and circle it. At the top of the entrance to Rowena's House of Splendor, you can either jump to the top of the gate, or Elusive jump to the other side, or Aetherial Manipulate yourself to the opposite end. Circle around the wall again using the upper platforms. This is the part where you have to do some short bunny hops onto those curved platforms twice. They look like these:
You cannot go through the bottom since there is a wall. Keep going until you reach the platform before the bridge! Then you have no other choice but to use Elusive Jump to reach the bridge. There's an invisible wall there, but if you angle yourself properly, you'll slide along the invisible wall and onto the bridge.
