Four identical attribute markings can condense into a Mysterious Chapter.
However, Mysterious Chapters also have their own structures.
A Mysterious Chapter condensed from four different markings of the same attribute is called a Fourth Rank Mysterious Chapter.
A Mysterious Chapter condensed from three identical markings and one of the same attribute is referred to as a Third Rank Mysterious Chapter.
And so it goes on.
A First-class Mysterious Chapter is condensed from four identical markings of the same attribute.
In terms of amplification effects, a Fourth Rank Mysterious Chapter can only reach a quarter of a First-class Mysterious Chapter.
A Third Rank Mysterious Chapter can only reach a third of a First-class Mysterious Chapter.
The same applies to the Second Rank Mysterious Chapter.
