20k feathers... save or spend?

I'd keep Axura as not only will she enable Ayra to move again, but she will also get a stat boost. 63 Attack...51 Speed....God help us all...XD

I would not suggest running Life and Death 3, she has enough speed and has decent defense that she shouldn't need that skill other than her native Swift Sparrow 2, which is already really good out of the box. You'd be overkilling your speed for nothing at the cost of defenses, and if it's to have an easier time with her Innate Dancing blade from her sword you can just run Phantom Spd 3 as it's affected by it.

It seems like you've made up your mind on Ayra already. If I were you I'd just look over what each hero could do more for me and decide from there. It looks like Arvis' most useful build is as a utility debuffer mage with ardent sac+recovery ring and valflame+ploy skill, whereas Ayra is a super strong player phase sword.
