Curtain of Light

The Devastated Banshee's spell was just about to reach completion and it was preparing to throw the mass of black substance on the ground when Will struck! A blade light hundreds of meters long extended from the tip of Will's blade and snaked upwards towards the Banshee. 

The blade light turned into a curtain of light that coiled around the banshee going upwards towards its outstretched arm. Eventually, the curtain of light coalesced around the ball and a slicing noise emanated from the point of contact. The sound echoed like a piano string that had been flicked in a hollow cave. The curtain of light that had formed dissipated into nothingness, disappearing as quickly as it had formed.

Soon after, the large supermatrix that had formed above the black mass also started to disappear, until all that was left was a seemingly unstable ball of black mass. The black orb of mist like substance imploded, while its remnants rained down on the Agonised Banshee. 

This resulted in explosion of yin type death energy that kicked up intense winds capable of easily uprooting trees. The Frozen Asgard maidens watched on stunned as the Agonised Banshee writhed in agony. Its already bony and ancient appearance became even more wretched as it was visibly breaking down. 

Pieces of its cloth broke of and withered away as if they had been eaten by the sands of time, while hundreds of cracks appeared on its skull like forehead. It looked like a lich that had been battered and bruised by thousands of blunt objects after having been dipped in concentrated acid.

Alison covered her mouth in shock as she said, "These effects, the banshee is being affected by its own spell?"

Before Lisa could get a response, another action quickly took the girl's attentions. 

The Metalos Blades that Lyra had used to encircle Will shrunk to a normal size and disappeared one by one until only one was left. The girls noticed an oddity once only one blade was left. Its engravings and design were a bit more affluent and pronounced than the others. The sword also had a presence far above the others, such that it could be felt even from a distance. 

Unfortunately none of them knew what this signified. Will however knew exactly what was happening. Metalos Blades were unique. The more were summoned, the lower the quality of each blade present, while the less blades were summoned, the greater the quality of the blades. Lyra had not relinquished every blade except two, resulting in each of these blades containing 50% of Lyra's power. The greater the quality and might of the blades, the more their designs changed to match.

Lyra quickly took action and flung the blade telepathically. But to the girl's shock, he did not aim at the Devastated Banshees and had instead aimed at Will!

Will rotated his body with blinding speed and adjusted his timing such that he was able to grip the blade midflight without reducing its momentum. Within that moment of contact, Will applied all the concepts he could and applied one more skill he had never used since he entered the dungeon. 

This was one of the skill books Will had gotten in the dungeons he had explored just after entering earth. A common skill that certain metal element users could use. 

"Magnetic Repulsion!"

After speaking the chant, the blade bolted forth like a projectile released from a rail gun, headed straight for the Agonised Banshee! 

The blinding speed in which the blade left Will's hand left the ladies without a chance to process anything, but one thing was visible despite the horrendous speed the blade moved at. The moment it left Will's hand; it enlarged into the largest size the girls had ever seen a Metalos Blade become and became as large as a small hill. Yet despite this sudden enlargement, it did not drop in terms of acceleration and bolted straight at the writhing Agonised Banshee.

Contagion Distillation Blast was a spell that was meant to cause large amounts of horrendous damage to a wide area, but the spell had imploded and fell back onto its caster with its power still concentrated. 

To make matters worse, the Agonised Banshee was suffering from damaged spiritual pathways after having a large scale spell disturbed. It was being destroyed inside and out while it barely had any awareness or control of its mental faculties. All three of its vessels were under attack; such was the consequence of losing control of a super large scale spell that had been fuelled by the world. Sometimes, if one was not careful, the world would turn back on them.

The Agonised Banshee was in so much pain that it failed to notice a Metalos Blade the size of a small hill heading straight for it with an alarming velocity.

Bam!

The blade, filled with the sharpness, armament and momentum concepts along with Truth, Swordforce, Yin, Death and Solitude lodged into the creature and forced it backwards. The creature resisted the pushback as the blade deeply embedded itself into the banshee while the many energies within added to the creature's suffering. 

Never had the Agonised Banshee faced such a threat. It was like a human being asked to defend themselves after being spun around and being beaten to a pulp. The banshee was disorientated, in pain and it could barely access any of its energies!

Because its spiritual pathways were in a berserk state, it could not use most of its abilities. To counter this, the creature tried to absorb the lingering death energy and poison around it to strengthen itself, which is when it noticed a crucial detail.

'I can't connect to any energy outside my own body. I have lost my spiritual connection to the environment!'

Unfortunately the creature did not have the time and mental faculties to ponder more on this as it could also detect that it had landed into a barrier of momentum filled Truth, left behind by Achilles as he trailed around. The creature used the rebound from colliding with this wall of Truth to stop its backward momentum while it tried to reach for the sword embedded into it. That's when it felt a powerful killing intent lock onto it from the side. 

The creature was already in Achilles trajectory, thus it was inevitable that they would clash. When Achilles saw the creature land on his path, he laughed with glee as he burst forth with all the energy he could muster. He quickly switched back to using the Metalos Blade and gripped it with both hands as he readied his concepts. Sharpness and Hardness coursed through Achilles as he called forth all the momentum he had built up during his entire charge. 

Achilles' spiritual pathways were already close to bursting as the young warrior was approaching his limits. There was a limit to how much energy and momentum he could carry in his body with Macedonian Charge. This was further enhanced by Lyra's Buffs and the power he was drawing from the Metalos Blade, allowing Achilles to become a great threat in the Banshee's eyes. 

The creature tried to pull the sword embedded in its chest out but to no avail. The sword was covered by a protective film of solitude that isolated the blade from any contact with a foreign object. All the banshee could feel was its grip sliding off the blade every time it tried to touch it. 

The blade kept releasing energies that tormented the creature while Achilles' dangerous figure loomed closer and closer with each second. 

Strengthening its resolve, the Agonised Banshee decided to sacrifice a portion of its Life-force to release an uncontrolled blast of death aura. This would leave irreparable damage; but at least the creature would survive to battle another day. Life-force was the only energy it had access to as its own World Energy was acting berserk while it had been isolated from the World Energy outside. Yet before the creature could attempt this, its figure froze.

For some reason, it was locked in place and could not move an inch. It failed to understand what was happening as Will's loud voice entered its ears. 

"I am the arrow that strikes the heavens and yet knows no redemption!"
