[X] Plan Don't Mess With Divinity
-[X] Get some distance between yourself and the barrier, then taunt White Soul into using Soul Rend against you
-[X] The moment she does, charge at her and call out [PEACE] in the Conceptual Language from as close as possible to stop her from reacting, then hit her with the Panzer Blade as often as possible
-[X] If she is out of your direct range in that moment or gets away from you, cast Celestial Severance or Starshine, whichever is more likely to hit her
[X] Plan Controlled Panic
-[X] Attempt to follow Red Rose's advice and Starshine White Soul's bodies, as well as the areas near her bodies.
-[X] Next, activate Core Purge, aiming at both White Soul and her Seal, wherever it is. Also try to get your Purge to effect the barrier if it can.
-[X] If Starshine doesn't work, try shooting White Soul. It might help.
[X] Plan Big Booms
-[X] Start blasting with Purifier Beam at your own feet and sweeping towards White Soul. Aim for as much AOE as you can as long as you avoid engulfing the barrier.
-[X] If White Soul backs away and gives a lull try to hit the barrier to weaken it, aim away from where Insight is located.
-[X] If White Soul moves to the barrier curse and fly far enough away that she can't reach you quickly.
[X] Plan Someday This Will Work
-[X] Tell Sega to go through the wall or the ceiling.
-[X] Fly about halfway down the hall and activate Core Purge along the way. Make sure to watch both bodies.
-[X] If she avoids it by going through a wall, carve a hole and follow. If she goes into the central structure, follow at max speed. Stay in the middle of passages/rooms in order to prevent her from using corners. Return quickly in case she's circling around to go for the others.
