This is the plugin I'm using https://perang-cemen.itch.io/rpg-maker-mz-petrify-system

In the video on the plugin page, when someone gets petrified they stay standing up. When I set <Petrify> in the notes and apply the Petrify state to a skill, when that skill hits a character, they go into the death sprite (laying on the ground face down). How do I keep them standing up? Also, I want to make greyscale versions of each character's standing sprite for when they are petrified. How do I set it to use this greyscale sprite for petrification on a per character basis? Or if there's another way to do it, I am open to suggestions.

EDIT: Okay, maybe I don't need the plugin. I'm still a n00b to RPG Maker (first project ever with any of its versions), didn't know you could make custom states. So I would just like petrification to have them as a greyscaled version of their standing sprite. I have learned how to use Asesprite a bit so I can color the one version of the battle sprite for each of my 4 characters there, so I just need to know how to make it use that sprite of each character when the Petrify state is on them.
