Heaven-Shaking Slash (動天斬, Dōtenzan) is a Sword Magic spell of considerable destructive power.
The Heaven-Shaking Slash lives up to its name quite clearly; its a slash so powerful everything trembles in its wake. Unlike several Sword Magic spells, it can be utilized with any sword so long as the user is capable of manifesting the required energy to make use of it properly. The Heaven-Shaking Slash works by concentrating an excess of magical power into one's blade, creating surges of magical energy leaking out of the medium which the spell is being used from. From therein, the user makes a slash, generally vertical, against the opponent in question. The slash builds up an extraordinary amount of momentum from the movement that goes behind it, therefore releasing destructive shockwaves of kinetic energy which can slice through inanimate objects such as trees and even steel with some effort. While the spell is very powerful and effective, inappropriate use can easily lead to fatigue and unwanted destruction of the surrounding environment.
