As the title implied, this is the chapter where I will explain how the [System] works. Sorry for the confusion for those who don't understand how it works.
—————————————————————————
---[Level Cap]---
What is [Level Cap]? The simple answer is the maximum attainable [Level] of the User, but it works somewhat differently in this story.
It works more like a Rank only for the User...
—————————————————————————
[Level 1 - 10] are in the same rank. Can a [Level 7] beat a [Level 10]? The answer is yes.
[Level Cap] for the [System] is...
[Level 1 - 10] = Need one SS-Grade to ascend to Level 11
[Level 11 - 20] = Need one SS-Grade to ascend to Level 21
[Level 21 - 40] = Need two SS-Grade to ascend to level 41
[Level 41 - 80] = Need one SSS-Grade and one SS-Grade to ascend to level 81
[Level 81 - 160] = Need two SSS-Grade and one S-Grade to ascend to level 161
[Level 161 - 320] = Need one EX-Grade and two S-Grade to ascend to level 321
[Level 321 - 600] = Highest level is 600
The stats except for [Luck] will be reduced by 5-Grades after the User ascended from the [Level Cap]. It doesn't make the character weaker; but for example, the SS-Grade for [Level 1-10] is the peak for that [Level Cap], but it doesn't mean the SS-Grade of [Level 1-10] is the peak for [Level 11-20].
—————————————————————————
The Highest [Level] in this is [Level 600]. But what are other characters [Level]?
---[Common Characters]---
East Blue = [Level 5 - 8]
South Blue = [Level 6 - 9]
West Blue = [Level 10 - 14]
North Blue = [Level 8 - 17]
Grand Line = [Level 9 - 20]
New World = [Level 30 - 60]
The No-name characters in One Piece aren't worth attention, but it is what it is.
—————————————————————————
---[Straw Hats Pirate]---
East Blue Saga = [Level 5 - 20]
Alabasta Saga = [Level 12 - 69]
Enies Lobbies Saga= [Level 46 - 104]
Post - Timeskip = [Level 85 - 270]
Post - Wano Arc = [Level 96 - 504]
How do you determine the character's [Level] for the [Straw Hats]? Easy weakest Usopp, Strongest Lucy. Zoro is slightly behind Lucy with a [5 - 10 Level] difference. Sanji and Jinbei are [10 - 20 Levels] behind Lucy. Nami is [3 - 10 Level] while Chopper is [7 - 10 Level] ahead of Usopp. Robin, Brook, and Franky are in the middle of the list.
—————————————————————————
---[Criminal Class]---
Should I really do something like this? Telling the [Level] of criminal? Oh well, let's move on. Considering the Shichibukai System has already got demolished, I included them in this list.
The Baroque Works = [Level 17 - 74]
The Seven Warlords = [Level 40 - Level 450]
The Yonko Crews = [Level 80 - 340]
The Four Emperor = [Level 20 - 550+]
Those who read Manga know who is the [Level 40] Yonko.
—————————————————————————
---[World Government]---
Hmmmmm....This is harder than the criminal one because we don't see much about the Navy, but here is my speculation for the [Average Level] for Marines in Grand Line. This doesn't count for Garp, Koby, Smoker, etc.
The Ensign = [Level 4 - 7]
Lieutenant Junior Grade = [Level 5 - 8]
The Lieutenant = [Level 6 - 8]
The Lieutenant Commander = [Level 6 - 10]
The Commander = [Level 7 - 10]
The Captain = [Level 7 - 20]
The Commodore = [Level 12 - 30]
The Rear Admirals = [Level 30 - 80]
The Vice Admirals = [Level 40 - 100]
The Three Admirals = [Level 500 - 520]
The Fleet Admiral = [Level 520] (Akainu)
The story [System] mentions that the Admirals are around [Level 300 - 500], but in reality, Admirals are considered equal. Akainu is probably slightly stronger than the others.
—————————————————————————
---[Grade System]---
How does the Grade work? The lowest Grade is [J-Grade], and the highest is [EX-Grade]. [EX-Grade] only was needed once you reached the [Level 161 - 320] cap.
[EX-Grade]
[SSS-Grade]
[SS-Grade]
[S-Grade]
[A-Grade]
[B-Grade]
[C-Grade]
[D-Grade]
[E-Grade]
[F-Grade]
[G-Grade]
[H-Grade]
[I-Grade]
[J-Grade]
Just like some of [System] Novel, the [Grade] determines the [Stats] of the main protagonist. The [Grade System] was actually inspired by [Danmachi].
—————————————————————————
I know some of you are still confused about this, but this is how the [System] works in my brain. Gacha Order is easy to explain because it is just a Gacha with a bunch of multiverse weapons and characters.
Will there be a Character or Weapon rate up? Like during a Special Event? The answer is yes, but it only will start once Luke and his crew enter the Grand Line.
This is how it works in my brain.
