yunalesca

I already beat her, but what is the best strategy for beating Yunlesca.

Umm...ain't there like two or three other topics for this?

Just don't change all of your party members out of being zombified. Unless they got Regen on them, leave them as a zombie. When I did it, after I had everybody come up and take a shot so they could get the AP, I had Tidus, Wakka, and Auron (my physically strongest set) fighting her, and Tidus had Auto Med on his armor, so every time he was Zombified, he healed himself.

I had Yuna leveled up to get Holy, that was very useful.

And I remember Shiva being my MVP of this battle. Even though she didn't have break damage limit, she was agile enough to avoid a lot of Yunalesca's attacks and get like three overdrives in.

use whatever strategy you want ( using holy is the better one ), just make sure you're zombified or you got an aeon on field before Yunalesca changes to her third form, otherwise you're dead meat.

She is pretty simple to me
Just keep your characters zombified unless you want to cure them
use the strongest attacks possible
I found only one purpose to Yuna and that was to use her Aeons

Here is a link to one of our many Yunalesca threads.
