Yeah, the Keeper was a pain in the ass too. But I don't think either of 'em were nearly as bad as Seymour was, on Gagazet.

I beat her, by the way. I think it was on my third try, just because I kept un-zombifying everybody, and when I made this thread and realized I shouldn't do that, she wasn't too hard at all. I just had everybody take a couple shots, do their thing (cycle through Yuna's Summon Overdrives, if I had any left), then my three physically strongest (Auron, Wakka, Tidus, in that order at the time) just whacked away at her. Tidus had Auto-Med on his armor, so he would always use a Holy Water when she turned him into a zombie, but the only time either of the other two weren't zombies was when they needed to be healed, so they'd use a Holy Water, then Yuna would come in and use Curaga and leave again. I didn't have to use too much magic...I can't remember if Lulu knew Flare by then, and I don't think Yuna knew Holy, so prettymuch all I needed was some curative spells and Haste/Hastaga.
