Description
It is a highly advanced Magic that generate massive vibrations, or shock waves, which can travel though virtually any medium, including the ground, the seafloor, or even in the air. This Magic can easily devastate an entire town with ease, although its limitations are noticeable: It took repeated usages to come close to destroying a Large Dark Guild base; the shock waves were blocked by the siege wall (albeit it was made from an especially strong metal superior to ordinary steel).
