Outcome

As the battle passed, Squire Heviluo began exerting himself tremendously in his attempts to prevent Kane from entering.

Eventually, it appeared he could no longer keep up.

THUD

He fell to one knee, sweating profusely. His exertion had also strained his healing factor. Even if he attempted to simply wait and recuperate, Kane would not let him. Every time he stopped using the technique, Kane would rush in and employ the Phantom Step technique, or he would attack for real, forcing the man to once again use a taxing technique.

Both sides were exerting themselves, however, Kane's Fulminata technique was fueled by the esoteric substances in his tattoos, while only his Godspeed technique consumed a lot of energy, however, it consumed it over time as opposed to an instantaneous consumption like the man's hurricane technique.

The Phantom Technique was a very light technique and did not require much energy, either mental or physical, to function.
