P. S. In general, I started all this in the hope of learning how to predict morale and luck, but it seems that due to their pseudo-random nature, you can't do it with just your brain...

By the way, thanks to this mini-research, I finally saw the animation of bad luck (a thundercloud and lightning) :)
