To be more precise, an awakened individual possesses a particular type of ability that can be considered a medium or a device which takes Synergy as input and provides output based on the device's function.
To understand it more clearly, one's ability can be considered a tunnel that has a particular shape.
According to that shape, when air passes through it, it provides output in that particular direction.
In the case of an awakened individual, that tunnel can be made only once, so further reconstructions are generally impossible, though there are definitely exceptions in most cases.
So, the tunnel, which represents an awakened ability, takes the air—here referred to as Synergy—and produces an output.
However, that output is the same as the functioning of the tunnel, without having anything extra attached to it.
Although the amount of Synergy can decide the concentration of the output, it doesn't change the result.
