Anti-Skill

Anti-Skill (能力殺封) is a special constitution that has the ability to nullify almost anything.

Description
Anti-Skill is a Spiritual Body constitution that has the ability to suppress or "seal" all physical and spiritual forces that the user comes into contact with (Although it cannot negate things that have both of these properties at once) and can be turned off and on at will. It can also shut down a majority of skills (including ultimate skills) and completely seal their use for a period of time. However, it can only be transmitted through the users direct touch and not through any mediums such as weapons.

Guy Crimson was able to bypass anti-skill entirely after some exposure.

Although Anti-Skill can negate physical force it does not make the user completely immortal. Diseases and Poisons can still take effect and things needed to live such as food and oxygen are still naturally needed.

Anti-Skill is not permanent. After some time without contact from it, the skills and magics that were shut down can be used once again.
