THEME:
Well...that was unexpected...
The Narrian continued to observe his opponent's movement, forced to rely upon his other senses to keep track of the creature as once again the alien matter surrounding his barrier was obscuring his unique red eyes. It was both equally as confusing and concerning that this stranger was seemingly disregarding the danger posed by the invisible aura, rushing right into it with reckless abandon.
Then again, everything about this Final Boss was an enigma. Managing to somehow survive a direct hit from his previous attack and still being able to move without issue as it was. How the cloud of alien particles filling the arena could originally be destroyed by said blast and could physically be interacted with, yet somehow apparently was not physical matter in any way, shape or form so as to be entirely immune to the freezing effects of his projected aura.
Regardless, no attempts were ever made to try and prevent the spread of the creeping ice, encasing the arena interior as it swiftly covered the walls, ceiling and floor. Virtually anything that it could latch onto. But the ice itself wasn't the true threat, merely a byproduct. Something Xavier would find out far too late...
Upon making contact with the creature's head, it would have been subjected to the crippling effects of the aforementioned aura. Assuming this thing had a brain of some sort, the physical matter within the body would suffer being flash frozen in an instant long before any ice crystals would begin to form. If the organic tissue wasn't outright killed in the process, at the very least it would be trapped in a state of suspended animation, halting any and all thought process including, one would imagine, the ability to conjure up its Dreadful Flames. Why the stranger waited so long to put up some sort of defense before the aura touched it was just...confusing to say the least, like everything else.
Perhaps it was just a simple mistake. But in a battle of this caliber, a simple mistake can prove fatal. Even had the flames managed to still manifest after the fact, it seems rather unlikely they would have been able to somehow cure the internal condition of being instantly frozen from the inside out.
In the event his adversary didn't just simply drop to the floor like a frozen popsicle at that point and could have somehow, miraculously still to pull off launching itself like Super Man at the Force Barrier, this had also been taken into account.
Using Xavier as an indicator mark for positioning, Dias' senses registered the Ether present within the thick layer of ice all along the ground in front of his enemy, stretching across the distance between them. The aura being projected from the Force Barrier was allowing for maintained physical connection by extension from himself and the rapidly spreading ice. At the precise instant the creature would have launched off the wall, the Ether turned unstable and went critical, triggering a chain reaction of massive explosions directly beneath Xavier after having fully committed its body to the act and leaving itself entirely exposed and vulnerable.
However, considering the disintegration blast had failed to kill the monster previously, the Narrian's strategy was to use the detonation as a means to kick the beast up through the open air ceiling, the explosion delivering more than enough force to interrupt Super Man mid-flight and viciously hurl him straight upward with brutal intensity. It was a good thing the arena was indestructible, unscathed by the devastating blast which no doubt would have left a rather sizable crater where the structure once stood. Whether or not it could have been capable of also killing the assumed invincible creature would have just been an added bonus.
Of course, Dias remained safe from the destruction behind his Force Barrier the entire time. As witnessed earlier in the fight, the shield worked on a very simple mechanic; whenever an outside force pushed against it, the barrier was designed to reflect any kinetic energy back which made it highly effective against heavy artillery fire or ballistic weaponry. Or someone looking to consistently heave a wrecking ball at it over and over and expecting different results.
Even if his opponent had been able to make it across the distance, the impact alone would have been reversed and all that applied strength being pressed against it would have either sent Xavier violently flying backwards in the same way the saw discs were and or the monster's own body would have been horrifically damaged if it was unable to withstand getting hit by an equal amount of force that was being exerted upon the barrier.
Granted, this was all merely academic as odds were that the stranger had likely just turned into a popsicle now laying on the floor, no longer able to continue fighting.
Meanwhile, the five Diamond Greatswords which had been sacrificed earlier had now reformed in the same manner they had been created earlier, now joining the other large, hovering weapons which had continued to remain in a defensive stance and poised to react to any threats in the event his opponent had magically shrugged off every single counter posed against it, despite how unlikely that scenario may have seemed.
