In terms of Bane, I almost always go -Lck since Luck, IMO, seems to be the stat that you can nerf and still get away with without much consequence. Secondary class is usually Cav, for the mov + Yato access and the excellent promotionss, or Ninja due to the usefulness of the class as a whole + Yato access when promoted. Bane is either +Str or +Def; depending on what characters I plan on using in the run, although I will say the endgame boss is much easier to kill when you have a +Str.
