Thunder ragnarok is out

With 45% attack down:
Raging overdrive is ~3000 party-wide damage and small chance to paralyze for 2 turns, as well as buffing herself with attack+double attack. I got hit with it 4 times and paralyze landed on one hime each time, but due to having 2 charge turns she fires it every other turn. I'd bring Propaganda over cleanse for this.
2 normal overdrives: one is a 3 hit attack, it went too fast so I didn't see the damage vv but it was large.
The other is a party-wide attack that does low damage and -20 burst.

My choices for Soul here would be Shingen if you can kill her quickly or Joan otherwise. Zephyrus helps as always.
