The path pretty straight forward. But before you proceed, I recommend add one more paradigm "MED/COM" and whenever you want to heal you can switch to "MED/COM" instead of "RAV/MED". The reason is that COM role will keep stagger meter from depleting faster so that you can continue accumulating stagger after you healed.

Save the game at Save Point. From there, you can see an open area but it is separated by an electric fence, inside is a Feral Behemoth. It's a fake wall because you can access from both side at the end of the fence.

Before you go any further, it's time to use our Crystarium Points again before we fight a boss. For Lightning, max out Commando, then Ravager, and Medic last. For Hope, max out Synergist, then Ravager, and Medic last. You should have unlocked one more accessory slot for both Lightning and Hope so equip Iron Bangle on Lightning and Silver Bangle on Hope.

Paradigms (Lightning/Hope):

• COM/RAV (default)
• COM/SYN
• RAV/RAV
• COM/MED
   
• BOSS (B-01): Aster Protoflorian (x1)
  Strategy:
  • Cast 1 Libra.
  • Start with COM/SYN until both of you have Protect and Shell.
  • Switch to RAV/RAV when your heal is green and switch back to COM/MED when yellow or below.
  • When the boss is stagger switch to COM/RAV.
  • Repeat.

Before you go, remove all accessories from Lightning and Hope because we are gonna need them for Sazh and Vanille.

Now save your game and go to the yellow mark.
