+Res -Atk Ninian

If just support, giving her spd 3 and wom is good enough.
If you wanna give her a lot of inheritance,
Light breath with spd refine
Sing
Moonbow
Fury/TA/Atk spd bond
Wom
Fortify dragons

you should really fodder that camilla for brave axe+ on a Cherche though

Sorry, i don’t see this working

She is a dancer so her attack stat doesn't really count that much
