And the REAL key to defeating him is Aeris's aultimate limit.
That would be trying MUCH harder than necessary. It took me 2 tries to beat this thing, it isn't THAT hard. I didn't even have the nail bat, or any Enemy Skills.

One other word so he won't hit as fast.

HASTE!!!!!
Exactly what I did. Congrats!!! *gives Halenite 3 cookies*
