Killing Mastery

The power to have a mastery and intuitive knowledge of how to kill any living being. Variation of Intuitive Aptitude. Not to be confused with Assassination Mastery, Killing Instinct or Slaying Mastery.
==Also Called ==
*Death Formulation
*Murder Intuition
*Murder Methods
*Great Murder Skills
==Capabilities==
The user has innate knowledge of how to kill any living being regardless of how powerful they are. This ability comes in great significance when dealing with seemingly unstoppable opponents and allows the user to end their lives with expedient efficiency.
They can intuitively kill by any means and in the most effective ways possible, use anything at hand to do so and, have no mental/emotional issues or moral dilemmas either before, during or after the deed. Users can perfectly and without a single flaw or mistake, know how to kill anything, whenever they want with zero effort.
The user has intuitive knowledge on how to kill to the point where they can easily formulate ways to slaughter much more powerful beings without the need for superpowers, utilizing the opponents’ weaknesses to inflict crippling damage. They can even choose whether or not the opponent should be kept alive or killed right away, allowing the user to indulge in much darker methods.
This is the ultimate killing mechanism, since the user will automatically kill with perfect skill, technique and timing. The users full and complete mastery in killing and anything related to killing makes them as the ultimate killer.
Unlike assassin mastery, users of this ability are not bound by the need for a quick and painless kill. They can choose how long they want their opponent to stay alive. Skilled uses of this ability include disabling through non-vital areas, sensing vital weaknesses to use against them, utilize those weaknesses for devastating effects, torture at disturbingly high degrees. With enough skill, the user can utilize their intuition to deal crippling attacks to their opponents. This can be used as a powerful fear tactic against them by utilizing their murderous aura to terrify them, even leaving a horrifying aura to resonate in the air where they had committed their acts. (Ex: A dog walking down the street with their owner before whining as they grow near a spot where a notoriously serial killer had brutally murdered one of their victims despite the victim’s body being disposed of by the police).
