THank for your help! Good way!
But you all forget one thing important.
I haven't kill enough Jumbo F to get enough Magic sphere (Yuna's Magic just about 120,flare deal 15000).And I think it is slower than Pain!
OK,since my Anima's magic maximum now,I'll use doublecast Flare for her.I just have to when Jumbo run low on HP and use pain to get overkill.
Thanks again ^_^
