o the dmg i was calculating was from a different save, which i had!
armor protects/mag resist:
Emily - F/B
Fubar - F/F
Hugo - C/F
Joe - B/F
Ayame - F/F
Landis - F/A+
so the testing i was doing was based on a F in Armor Protect (Emily and Landis) and different magic defenses. it may be the Arm. Prot can improve Defend and M. Resist doesn't, but further testing needs to be done.
