Ah..a dark aeon..I have heard that term before actually..so.. if I defeated this aeon would I get it to use for myself? Or not?

Is it possible to get HP above 9999? Do I need a special armour or weapon for that? (Sorry if that's offtopic)

I'm not sure if I will bother to challenge it again, unless I get a LOT more HP....may just avoid it. I am such a wimp
