Anti-Skill

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

Abilities
Anti-Skill is a Spiritual Body constitution that has the ability to suppress or "seal" all spiritual/magical forces that the user comes into contact with from aura to magic and then use the negated force to counteract physical energy and can be turned off and on at will. It can also shut down majority of Skills (including Ultimate Skills) and completely seal their use for a period of time. However, it can only be transmitted through the user's direct touch and not through any mediums such as weapons. It also cannot negate things that have two forces at the same time like Mystic-Art.

Although Anti-Skill can counteract physical force under most circumstances, it does not make the user completely invincible, purely physical attacks unenhanced can still damage the user, diseases and poisons also can still take effect. Depending on the user state, things needed to live such as food and oxygen are naturally still 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.

Trivia

 * Guy Crimson was able to bypass Anti-Skill entirely after some exposure.
