despite high evasion and high defenses, seeing my mages with less than 2500 HP really makes me worry. And thats their DEFAULT max hp (you could always continue with the sphere grid). Yeah, and since critical status gives you nil, I always worry. In FF8, critical status increases so many stats and chances.

I didn't like Yunalesca's status attacks, so I figured it best to dish out your overdrives in her first form and end it as soon as possible. Aeons can come later in the battle, and note that if you have your characters almost at the end of their default sphere grid, having a zombie effect won't hurt you too bad because Regen only hits one person, and her mag. attack is low.
