[Congratulations! You have killed a shadow mirage of the Deceiver!]
Sebastian fell in love with the Night Rakshasha beast race due to some main reasons, it was because of their stealth and assassination abilities.
And now, in just a few weeks' intervals, this living doppelganger already proved to be living above what he expected to get from it.
Just like a lot of races were associated with specialized sounds and skills that were finetuned to their race, Night Rakshashas were synonymous with their race specialty killer move, assassination.
This was undoubtedly their strongest skill.
This was a skill that fell into the rare category of OP skills that could allow beasts to skip levels to defeat their opponents.
The requirements to use it were steep as it required the Night Rakshasha to sacrifice 70% of his health points, but in the process, he received the ability to deal a horrifying amount of damage in one move.
