Rankings/Grades are to help evaluate herbs in easy separate categories and to avoid clashing.
THE RANKINGS/GRADES MENTIONED ARE TO HELP CATEGORIZE HERBS CHANGE IT YOURSELF IF YOU WANT!
Sub categories are to further evaluate herbs split can be split into stars out of 10 or just low, medium and high it can be split further into high medium stage or low medium stage.
Eastern Fantasy Grades :
Mortal
Spiritual
Earth
Heaven
Immortal
These are some basic base grades as you can further split it into more categories but I can't think of any solid ubiquitous grades. (Example : Yuan Stage Herb or Golden Core Stage Herb)
basing on Cultivation Levels are a good grading system as well.
Video Games Grades/Tiers :
Trash
Common
Uncommon
Rare
Gold (maybe)
Unique
Epic
Mythic/Mythical
Legendary
Some Video Games novel use a colour based grading system usually going from
Grey
White
Light Green
Green
Dark Green
Light Blue
Blue
Dark Blue
Pink ( have only seen example in real Games)
Gold
Purple/Violet
Red/Orange
(either red or orange as some use red and some orange but one might be higher)
There are also special Tiers :
Quest item
Growth (mostly irrelevant)
Unique
(Depends if it is a special tier herb or not on author as some use it differently)
Sealed (Mostly irrelevant)
Magical Realism :
Magical Realism usually follow the video game ranking or Eastern Fantasy ranking or have their own independent ranking system giving us no commonly found grading system in Magical Realism.
Fantasy :
Like Magical Realism, Fantasy usually have their own ranking system giving us no commonly found grading system or follow Video Game's and Eastern Fantasy's Grading system.
Sci-fi
Sci-fi novels usually don't have one or use their independent system as most sci-fi novel differ from each other or copy the other ranking system giving us no commonly found grading system in Sci-fi Novels.
Seems like I lied to myself and you guys, still auxiliary chapters Haha but gotta get this out of the way for the non-educated readers
Next Chapter is where it really starts
Rankings could be changed but pretty lazy as it's hard to individually find a grading system and a commonly used one beside Eastern fanasty and video games as most don't list it.
Magical Realism, Realistic Realism and Fantasy usually copy Eastern fantasy/video games grades or use a completely different one to each other
