I can understand having Holy at that point, but Auto-Life? That's excessive.

This playthrough, I have probably overleveled severely. I just beat Flux, and Auron is currently doing anywhere from 5800-6200 with every attack. Which is probably excessive, but it will balance. Also, at this point Yuna will probably have Holy by Yunalesca.

On the topic of Yunalesca, element eater armor is your friend. It allows you to heal yourself without removing Zombie.
