Capítulo 1992: "Detour" 

For example, a water element ability user could actually sense things through water, but if the surrounding was dark, they also could not see anything. 

There were drawbacks and disadvantages, but elemental ability users had always been more powerful and all-rounded than rare and unique abilities. 

It looked like abilities such as weapon manipulation or various strange abilities were stronger than elemental abilities, but the truth was not like that. 

In most cases, elemental ability users would be surrounded by a lot of natural elements, so even if they could not conjure the element out of thin air, they would still be strong. 

Many solo ability users with unique abilities could not fully exert the potential of their ability because their ability was 'incomplete'. 

It was as if people with only one ability were limited to a certain power fragment while those with more than one ability finally got the complete power fragment.
