I personally think you should use this camilla as Brave Axe+ Fodder for Cherche, she does the role better than camilla in every part except using ploys :)
I have a + Spd/-Def Camilla and I fun her with carrot axe (speed refined) to minimize the fury penalty. But That is a seasonal weapon and TBH Slaying axe is probably her best weapon so that she can activate her special more often.
