There are all kinds of Skills in the world of Hunters. Some are common, simple enhancements that increase one's strength, boost speed, or grant elemental affinity. But then there are the problematic ones—the Skills that don't follow the norm, Skills that alter perception, twist space, or even rewrite the flow of reality itself.
The difference between these two types is like day and night. And in a fight between Hunters, the outcome isn't always dictated by Stats alone. More often than not, it's the Skills—and how they're used—that decide who walks away breathing.
There have been countless cases where a Hunter with a Unique Class fell at the hands of someone with nothing more than a basic speed enhancement. In a head-on clash, speed often means survival. The faster you are, the quicker you can react, strike, and kill.
However… that rule only applies when your opponent plays by the same logic.
And River never played fair.
