PHYSIQUE AND BLOODLINES
There are infinite physiques, bloodlines and races in this world. They are also ranked in the universe:
From
F - SSS → EX → TRANSCENDENT → PROMODIAL → CHAOS → ORIGIN →TABOO.
These are all the levels of PHYSIQUES and Bloodlines.
*Spoiler
The highest bloodline in Orion's universe is of EX rank, and the highest ever recorded in the world is of Origin rank.
Different bloodlines and Physiques provide different abilities, skills, power ups and rights.
The bloodlines and physique are only shown on the status if you have any.
TITLES
Titles are special privileges, not granted, but earned by certain people if they complete a set of requirements. They have no Ranks, but can be unique. They are special in the way that they are the records of major defining parts of a person's life. They can give access to certain abilities, skills or power to people. Some major abilities and items are also accompanied by Titles, their existence, potential and power being so immense that just owning them makes one eligible to get a title. Like the holders of the Authorities of sins.
CLASS
Classes are the paths that different people walk on (unique to Orion's universe, or to any other universe with a class system created by the universes will)
They are a record of a summary of a person's life and how they lived it.
There are three types of classes,
Ordinary:
A path many people have walked on.
Rare:
A path few have walked on.
Unique:
A path no one has walked on.
Ordinally the more rare a class is, the stronger power it grants its user, because a path to greater power is more difficult and thus less traveled. But that is not absolutely the case.
These types just indicate how many people have walked this path and not its strength.
There can be certain unique paths that no one has walked on, but are even weaker than ordinary paths.
Moreover Unique classes have never been recorded before so one has to discover and explore it on one's own.
People can also pass down classes in the form of inheritance, and when other people walk on the unique path discovered by a person, that path no longer remains unique and becomes rare.
Different classes grant different skills, titles and power boosts.
