So anyone else beat Penance and the Dark Aeons?

[Doc Holliday]

Give you a hint, don't rely on your Aeons! It will take time but you need to raise all you character attributes (well at least 3 of them, preferably Wakka, Auron and Tidus, best combination) to 255 and then you need to get their celetrial weapons and some aromor that has +20% defence, counter, auto potion, and something else I forget =\

That's some pretty bad advice, Aeons are really useful for sacrificial lambs. And you don't need full stats for Dark Valefor, either.
