If you frequently use Frederica in story battles, getting the Clear Skies, Damage Up passive skill is a great way to improve her offensive potential. Most battles in the story will have clear weather, so you can use this to your advantage.
The upgrades available for Frederica's second weapon rank boosts her offensive capabilities. K.O. TP+ allows Frederica to have self-sustain her own TP, as long as she can keep defeating enemies. You can improve this by getting Scorch Damage Up to make the ability stronger and take down enemies faster.
