Icecrown Citadel (19)

This power and Fel look somewhat similar, which disappointed the Witherer. If this green "evil" was truly related to Fel, at least he could experience how it could change a person's mind.

The "evil" power primarily manifests in control, specifically the control over corpses. Nathanos lacked the strength to withstand Sindragosa's fierce chill. To his surprise, just as the Lich King's Frostmourne could chill him, Sindragosa could as well.

The scattered fragments of young dragon bones were summoned by Shadowmourne, gathering and floating around Nathanos amidst the low-frequency chanting of the runes.

"Now, feel the boundless power of your master and the despair he has bestowed upon you!"

Boom! Sindragosa unleashed a power that covered the entire area. Nathanos's cloak ripped wildly backward, and a gust of cold wind blew through the gaps in his bone shield, catching on his face.

The violent shockwave caused Nathanos to cough up a mouthful of dark purple blood behind his shield, his entire body feeling numb and tingling. Then, blue-white frost condensed on his arms, legs, forehead hair, and even the blade of Sulfuras. His mind was unaffected, but his mobility and speed were restricted.

The Witherer cursed under his breath. 'This magic can actually interfere with my senses.'

The Undead are moving corpses. Each blink, each step, is no longer controlled by the brain's nerves, but by necromancy. The higher the level of necromancy, the more powerful the resurrected person becomes. Instilled with specific ideologies, they execute the tasks conveyed by those ideologies like machines. The connection between the Undead's consciousness and body also depends on its affinity with necromancy magic. Low affinity results in a mindless zombie, like Ghoul; higher affinity results in Death Knight retaining their soul and cognitive abilities.

Therefore, rather than saying that Sindragosa's magic made Nathanos sluggish, a more reasonable explanation is that the souls of the Witherer had a lower affinity with necromancy.

Is this temporary or permanent? Nathanos was extremely worried.

"It seems you are the strongest servant under the Lich King. I have never encountered anything like this before, not even when facing the Lich King himself." Nathanos pushed aside the bone shield that had been frozen into an ice sculpture.

Shadowmourne transforms into a blood form, and the amplification temporarily offsets the negative effects of Sindragosa.

The bad news is that Nathanos can no longer freely use other forms of Shadowmourne; the good news is that Sindragosa's power has been weakened, and unleashing a terrifying skill will consume the caster's own power. The Frost Queen has clearly lost the confidence she initially had in achieving victory.

Seeing that the intruder was still alive, Sindragosa spread her wings to their widest point and soared into the air, breaking free from the platform she had sealed off. Nathanos didn't believe she would escape; instead, he intended to defeat her in the safest way possible.

While in the air, her range of movement was unrestricted, and the Undead below seemed to have no ability to control the air except for the bow and arrows on their backs.

'The gaping hole in her abdomen is no longer protected.' Nathanos was secretly pleased; only when Sindragosa flew could her weakness be completely exposed. Now there were two problems to solve: first, Sindragosa was constantly moving; second, her two front claws might block attacks from the Witherer from below.

'I must get her attention.'

The Witherer dodged the frost bombs hurled from Sindragosa's mouth. In return, he retaliated with his own bow and arrows. The bone bow given to him by the Lich King upon his resurrection was cursed; wounds inflicted by its arrows would not heal, but this only applied to the living. For the fleshless Sindragosa, Nathanos's arrows were merely more powerful than others.

'What should I do?' The Witherer wondered to himself, his attacks having little effect. 'How can I expose Sindragosa?'

He had an idea, but it was extremely risky. If it failed, he would have no chance of killing Sindragosa.

'But... this is the only way.' Nathanos gritted his teeth. As he thought this, red lines spread from his eyes to his cheeks. The intense pain caused Nathanos's whole body to spasm, but he knew he couldn't stop now.

As his legs turned into black mist, an even more excruciating pain surged forth. The Witherer struggled and howled in fury, using the agony to propel his movements with speed and precision as he flew toward Sindragosa's head. The Frost Queen had discovered Nathanos's ability on her way here. She could tell that this transformation was almost a one-time event, and if it were released a second time in a short period of time, it would inflict unimaginable pain on the caster.

"This is your last struggle, but I was prepared for it," Sindragosa cried, the energy flowing within her skeleton clearly visible. This final blow from the Undead was undoubtedly powerful, making it worthwhile for her to fight back with all her might.

Boom...

Shadowmourne slammed into Sindragosa's head once more, flashes of red and blue light alternating, a piercing screeching sound, and countless shards of ice erupting from the center of the collision. This stalemate couldn't last long; both sides knew this, and whichever side couldn't hold out, the only outcome would be them both being thrown back.

Shadowmourne was not enough to break through the protection Sindragosa had placed on his head.

"You can't win, let's end it."

"Don't think you've won!" Nathanos said with difficulty, each word distinct.

"Do you have any other way to change the course of the battle?"

Nathanos spat out a mouthful of blood, the red color dissolving into the wind. "Do you know? When any creature is thrown back by a huge impact, its limbs and brain are unable to respond because they don't have time to adapt to the situation."

Sindragosa was taken aback by Nathanos's words. The Witherer's power was waning; he had no chance of resistance. All that remained was his last shred of willpower. What chance did he have of turning the tide?

Perhaps seeing through Sindragosa's thoughts, Nathanos laughed loudly, "Do you know the power of mortals? Do you know my true strength? Have you ever witnessed it?" The Witherer moved, just for a moment, as one of his hands slowly loosened its grip on the handle of Shadowmourne's axe.

"What!" Sindragosa exclaimed in shock, not Undead had voluntarily given up the attack, but because she realized that the opponent had another attack coming, a fatal blow to her.

The roar soared into the sky. Just as intense as the sound, Sindragosa and Nathanos were simultaneously thrown backward by the blast.

When any living being is thrown back by a huge impact, its limbs and brain are unable to respond because they do not have time to adapt to the situation.

Sindragosa felt it; she could only face the pressure head-on. But her eyes remained open.

Nathanos could no longer maintain his semi-real state, and his legs returned. He merely spun in the air for a moment before regaining his senses. He was convinced that Sindragosa was not yet here, and that the Frost Wyrm was a hundred times his size, and would experience a much stronger impact.

"Go and release your anger."

Shadowmourne was thrown out by Nathanos.
