In addition to being able to see the weaknesses of a target, the exclusive trait of Fool's Shadow, [Twilight of the Gods], can also predict the target's next action through changes in their nerves, blood flow, breath, and body.
This allows Fang Mu to effectively defend himself.
It led Fang Mu to make a decision. He must choose a Ghost Device that excels in defense to make up for his own shortcomings in that area.
One downside to Twilight of the Gods is that once a particular target is anchored as a divine being, it must be killed before another target can be anchored.
Therefore, in battles where life and death are not on the line, Fang Mu can't casually use the exclusive trait, Twilight of the Gods.
Twilight of the Gods also serves as a lifesaving measure that can be used in critical moments.
It might be decisive in some battles in the future, killing the enemy outright.
