yanfly's force advantage plugin can force player/enemy advantage or no advantage for the next battle using common events.
combine with yanfly utility common events so the common event will play after every battle win/escape.
I really get the feeling I should be doing regular YouTube videos whenever I make something cool in my game, instead of waiting for massive changes. But not going to lie... I always feel like it's never quite enough to merit an update, until it's a drastic change.
