Maiden of Orleans for healing and mage of flowers NP generation

For farming, usually nothing. Besides, we will use her NP rather than her face card at farming, so no CC for farming. For CQ, well, it's better to adjust it according to the fight itself. For example, if the enemy spam charm or stun, you can use anti-immobilize CC. If the enemy often use debuff, use debuff clear CC.

Buster 1: Da Vinci-chan

Quick: Holy Night's Aurora/Improbable Phantasmal Horse

P.S. Since she's a Berserker and they naturally have the lowest star weight in the game, so if you want to go with the crit built, you may probably wanna tag her with someone who can provide her stream of stars per turn like Andersen or any other Arts support with 2030 CE like Tama, Castoria, Cas Gil, Paracelsus
