The shadow is not a flashy creature by its nature. Flashy means, its position would be determined, and there was a chance that the opponent could escape using only their vision. So, it never does anything flashy.
The outcome is important, not how flashy one is.
Especially now when it can attract unwanted attention to it from someone. So, it used one skill that no one has ever seen before, none that is alive anyway.
The debuff skill used was a bit different. It is a unique skill.
Unique skills are something that no one in the world would have as long as the one bestowed with them is still alive. As there was no way one could snatch skills from their kills, there was no hunt for Unique Skill holders, or else everyone would have become a target for someone.
The shadow got a Unique skill called, Stack Power Loss skill.
It was a weird name, but with how it works, that name is very apt.
