Shiva Momento

[Pumpkin]

So apparently to get this I need to unlock a level 55 coliseum battle, but it's not appearing. I've done all of the battles up to level 62 and I did the level 40 fight with Shiva and Ifrit. I'd rather not have to imprism the level 40 Shiva because I just want to transfigure my Mishiva instead. I'm at Chapter 21. Anyone know how to do this?

I thought you get it for defeating Shiva? Or is it capturing her? Either way, just do the L40 one again and try doing both of those two things. She's pretty easy to capture, thankfully.

I don't remember having any issues with this at all. Have you finished the game? It might be in the end-game that you can do it.

EDIT: As I typed that, the more confident I became that it is in the end-game.
