(The post-game Enah that is part of the strengthen event.)
I've defeated her on Easy, (Normal, Hard and finally, Chaos. Even with stats maxed, it was a near thing. Obviously, I don't have a strategic mind. Brute force is my only tactic. Lol
So, if you beaten her on higher difficulties, please share your winning wisdom.
EDIT:. So my lame brute-force "strategy" does work, even on Chaos difficulty. Stats and weapons were maxed. And you need to be patient. It's going to take some time.
She summons pet turtles. If you have an empty spot in your formation, she'll put one there. Summon your own 3 pets to fill them first.
The first turtle isn't so bad. The green turtle is a real pain. It's an anti-healing pet. You can't regain HP, MP, or AP. Well, if you're KO'd and revived, you will be revived with HP.
When she has just a bit of her HP bar left, you'll be hit with an attack that leaves you with 1 HP, 1 MP, 1 AP. So if you haven't killed the green turtle, hope at least one of your characters survives to resurrect the others.
I hadn't killed it. She was down to just a hair's breadth of HP, and all my characters were in the 1's. Figured we're doomed anyway...screw it...hit auto.....and beat her. Hey, so I suck at this. Still won the platinum medal.

I only beat it on hard right now, but my guess is:
spam a toooon of the flinching item, she takes 2 turns in one sometimes (maybe always?) so it'll only stop one of those
farm out guild coins for maxed out muscle/magic passive items
farm enah for glowstones (auto easy -> spend them in the secret shop for the dmg multipliers and I can auto normal now), spend it on secret shop stuff and roll for pets and stuff
Hey, so I suck at this. Still won the platinum medal.
