Nervendruck

Nervendruck (脈所の網羅意志の強迫服従 (ネルヴェンドラック) Neruvu~endorakku; German for "Nerve Pressure", Japanese for "An Encompassing Will's Compulsive Submission of the Vital Points") is considered to be one of the most gruesome forms of the Black Arts, as it literally breaks the opponent — inflicting as much pain as humanly possible.

A form of Caster Magic, it's unknown when it was created or by whom. However, it's rumored that a single use from it was able to destroy a vast army in a mere instant; their cries of agony heard all throughout the land, frightening those who've heard it. Upon discovery of this potent & cruel art form, the Magic Council placed a ban on this magic — carrying out heavy & severe sanctions on those who dare use it. The power of this form matches that of Crash & Destruction Magic — both known to extremely powerful magics in their own right.

Currently, there are a few users of this art form — all of whom are masters, thus considered to be highly dangerous.

Description
"Like a doll, I will break you in so many ways. I will twist and bend you to the point that you won't be able to function properly. And trust me, the pain from it will be exquisite to see — showing on every inch of your pathetic face. You... will be my puppet!"

- A common quote said by users of this art form.

Trivia

 * This power is based on Pernida Parnkgjas's Schrift power, "C" — "The Compulsory" & Yhwach's use of Blut from the anime manga series, Bleach.
