Actually, I've noted that even with normal attacks, Flan's pretty powerful.
Then again, NG+ file, so I don't have to mess with recruiting her. I got tired of the grind, and skipped straight to the experimenting.
And so far, despite not having a lot of gear, I have more than enough SKP to make up for it. (Again, thanks for the help Ikari! Can't say it enough.)
...Fridge Logic moment! If she's this beefy without equips....Oh shit. Blue Sabers are really gonna make things beastly.
Incidentally, on my main runthrough, the Flying Squirrel never dropped. But on the experimental run, it's droppin' like there's no tomorrow.
As for the active-bar busters, enough SPD can compensate for that. Either by SKP grinding(which takes ages.), or Equips.
