Assassination-Style: Soul Cutter

Soul Cutter is a technique derived from the Assassination Technique that allows its user to combine Fūinjutsu with Kenjutsu to inflict a wound that cannot be healed by normal methods. It got its name from how the effect mirrors the effects caused by a damaged soul and how that kind of wound cannot be healed by normal methods.

Description
The technique forms a thin layer of chakra around one's blade. When the user attacks their target with a swift slash the chakra is applied to the wound and bind it with a seal that can block out Medical Ninjutsu. The name "God Slayer" comes from the wide range of Medical Ninjutsu that it can block out it can go so far as to block out the Regeneration Ability, which makes it seem as if the wound cannot be healed. The only known way of healing the wounds inflicted by the technique is destroying the seal before using Medical Ninjutsu and how difficult that will be various from user to user.
