I actually took Thetis as my physical duelist for valkyrie's superior utility as secondary UP generator, and paralysis immunity being pretty unique additional utility just too good to pass up) And while Knight Princess's AW ability was one thing I also wanted to include, Claudia's true damage without a need for Awakening or Skill Awakening fits the limitations given better IMO. Minimax also helps)
Well, that 3 UP can be pretty big, and soldiers are not supposed to face anything too dangerous anyway. But, with AW Jerome, Katie is equally good.
