I just recently, started to play FF 12: Revenant Wings. And I'm hooked. I don't get enough rest now because I keep on playing it. But I just got Ramuh as 1 of my espers and yet I can't use him. How do you get to use rank 3 espers? I'm having a hard time fighting stronger yahri, I need 1 rank 3 esper. Is there a special ring or something within the game's story that gets me to use rank 3 espers? Thanks guys!
