I’m leaving this here to put stuff that author probably forgot to give general explanation of some common knowledge from “She is Not a Witch”
Talent/Ability/Item/Pathway Grading system:
In general, Sequence 1 = Mundane Stone, Sequence 2 = Black Iron, Sequence 3 = Bronze, Sequence 4 = Silver, Sequence 5 = Gold, Sequence 6 = Pearl, Sequence 7 = Coral, Sequence 8 = Crystal, Sequence 9 = Epic, Sequence 10 = Divine.
Based on average strength of sequence number. Which means pathway with lower sequence number could still be graded as that of higher sequence if they offer similar performance output.
Then, there is quality classification. Starting from: Flawed, Normal, Excellent, Outstanding, Rare, Perfect, Legendary and lastly Mythical.
