Hmm...I've gotten all the armors in the game (the ones you can obtain without cheating, that is
) I've checked them all, and very few of them give any Psycho Defense increase (they all increase Defense, obviously, and some do increase Psycho Evasion as well, but, aside from the Psycho Boots for Heath and the Buddhist Turban for Basil, I don't think there's many that increase Psycho Defense). I don't think that "NA" armor is available in-game...at least, I never found it (though there WAS that one chest at Chichen Itza you can't get...)If you check melonseller's post, he discusses some interesting things in the game, including armors and weapons which might not be available in-game (though you probably already read it).
