Playing Final Fantasy XIII-2 on PlayStation 3, I fought the Long Gui, and lost. I selected "retry", but chose not to fight him, again.
In my next battle, with a weaker enemy, Noel only had a critical level of HP.
Every battle since has started with the same critical level.
He can be cured with wound potion, but once the next battle begins, he is back to critical. I even tried letting him die, to use a phoenix down, but that didn't work either.
What should I do?
