Help with Felicia

+Atk/-Def is possibly the best IV, her Attack is so low. +Spd is somewhat if you give up on trying to get any damage aside from special activation.

A Ploy C skill (aside from Panic Ploy) can work very well on her. She also appreciates a relatively wide range of Chill skills thanks to her speed and universal adaptive damage, but those are rare skills, and most players should exercise caution before foddering those.

A can be Fury, Life and Death, Swift Sparrow, or Death Blow, possibly Mirror Strike, Attack/Speed Bond, or Brazen Atk/Spd. B can be Renewal (which I like to pair with Fury), Guard, a Breaker skill - the B is very flexible. Desperation is an obvious possible choice, especially if you make a Brazen Attack Speed/Ardent Sacrifice sweeper.

Hi there, I have Felicia+6 and I definitely recommend +atk supported with a hone. I can't count how many times I was short 6 damage or less.

What do you want her to accomplish? Just check enemy mages? Kill stuff by initiating into them?
