So, I have enough Thunder Regalia that I could nab a Soul Weapon, but I'm not 100% on which Soul. Joan of Arc is my Primary Soul, though I also have D'Artagnan and Andromeda Mastered. I'm working towards Morgan and Hercules at the moment, but with 100/600 Holy Soul P towards Morgan and 10/900 Soul P towards Hercules (I still have to unlock Achilles), those are a long way off.
Thunder seems to be very offense oriented with no party healers at all, so I'm tempted to use Andromeda to shore up their survivabilty, or I can use Joan's defensive abilities. Or I can chuck caution to the wind and go for all out offensive with D'Art.
Pictured above are my available Thunder Kamihime (Not a lot to choose from). What am I better off focusing on with Thunder Souls? Defenses, Healing, or Offense?
