Dissidia Ghost Battle - Emperor vs Zidane (Steiner)
Emperor vs the Steiner Ghost card. Emperor and Zidane are both level 100. I haven't used Emperor that much so I'm not that skilled with him. If the Emperor fights I've seen here are an indication, fighting the AI with Emperor is very different from fighting a human.
The arena was chosen randomly but I got Pandaemonium, it worked out pretty well I think. I had to unlock Zidane so the camera would give me a better view sometimes, but I managed once I figured out the layout of the place. And no, don't ask me how I avoided that Grand Lethal, I don't know either.
