Your God Mode option needs to be readdressed. It only affect health which is not true God Mode.
If your party leads are killed by Status Ailments like, Curse. You will literally be stuck in the battle for hours on end if you're fighting a high leveled mob because the extra units around you are using basic attacks or not attacking at all due to the "Botched" mode Square Enix uses in the game.
If you can look into a way to increasing Status Ailment Protection or nullifying it altogether, that'd be awesome and a great help.
Other than that slight issue I've come across twice now, all of the trainers options work as designed.
