Not so much a "new" idea, but with your Breath Effects plugin, I actually split it into two as I only wanted the effect in combat for now. I was getting a weird line glitch on the event/tilemap version, but I'll just blame VisuStella for that lol.
That line glitch problem happends with your use a Plugin that Zooms the camera, you need to test changing values on that plugin until the line dissapear
