Set gives maximum defense shred, allowing Rosetta to both support the main DPS and also come on-field to sub-DPS
Great performance in all possible content
Placement Note: Placing Catherine on the bottom row is optimal as she has higher ATK, but putting her on top allows you to more easily swap her out with Darwin if you Hypertune 4/5/6 Leeuwenhoek; you may want to do this if you care about scoring high in Phantom Pain Cage
