I looked at the translation dictionary. The shining herb is also supposed to rejuvenate monsters.
By the way, I partially edited the google document that is supposed to be the public translation dictionary.
Any tips on how to notify the game about my changes so that it can update the dictionaries when someone runs the game?
The sheet seems to autosave when you make changes, so I don't think it's a problem of saving.
If you enjoy it, you can write a private message.
