BEST Felicia build?

i'm running a mixed phase felicia which works really well with +Spd/-Def

Plate+Eff
Glacies (she also has aether and thats actually kinda decent on her but i prefer glacies every now and then)
Darting Blow
Windsweep
Speed Smoke
Quick Riposte seal

you can probably go with fury and that would work a bit better but darting blow lets you use windsweep more effectively and has no recoil so you can use quick riposte longer

Best Felicia build? Can't really say, but I can give a Felicia build that works really well, although it's a bit common.

Felicia (Neutral)
Felicia's Plate (+Eff)
Reposition
Glacies
Fury 3
Desperation
Atk Ploy 3
Distant Def 3

Neutral was the best IVs I had out of all of the Felicia's I had, so I'm gonna try to get one that's +Spd (or +Atk) and possibly get her to +10. Glacies can demolish units, even if they're on defense tiles, it's quite hilarious.

I'm also on my way to +10 her and my build is still a work in progress, because I'm slowly getting a hang of what she can and can't afford to do. In the picture, you can se how I'm planning on building her.

Weapon refine is kind of unclear. I will not go for the effect refine myself, because it seems to me like a less significant bonus than a stat increase refine, because you will be fighting mages most of the time, which you can easily kill without your special. This leads me to either go for res refine or spd, which give you added sustain thanks to a couple of extra hp as well.

The A slot choice is pretty straight forward. You get fury for an overall stat boost (which she can use so well), which goes towards a more offense oriented build. The other big option is distant defense purely for enemy phase tanking, which is nice, but can be done by archers with guard bow more effectively.

B slot seems like easy desperation if you choose fury, but you might go for quick reposte for baiting speedy mages (like the newly released Ishtar). There is also guard, which makes sense, but it's not really my personally favorite skill.

C is always flexible, but felicia is an exceptionally good ploy user.
