Hm, it appears that dmg cut, like 40% from Joan's "Voice of god" is less potent if you have atk debuffs stacked on enemy... Speaking of Joan, how does her Def bonuses apply to this formula? Is that a direct -23% to DMG modifier? +23 to DEF up? (Im trying to figure out who is more potent at keeping your party alive at high dmg bosses, like blue raids? Andromeda with a flat 1600 heal or Joan with all def bonuses, dmg cut and regen...)
