Yvaine's eyes glowed with a gentle, violet light as she observed Vale activating the Spell.

Although she preferred staying inside Vale's shadow, she still liked it when she was outside, especially in this Dark Soul Tower with rich Dark Energy.

'So he's doing a mutation this time?' Yvaine thought as she saw Vale's body start distorting.

"This human can really be so random sometimes."

She understood the importance of this moment and the risks involved, so she carefully observed the young man.

Soon, Vale's transformation commenced.

Yvaine's gaze never wavered, her eyes filled with a mixture of awe and concern as she witnessed a familiar aura of an Imp taking hold of him.

'It wasn't just a simple disguise... A perfect transformation?'

She could sense the immense power surging through Vale's body as it shrank and contorted, gradually assuming the form of an Imp.

Yvaine observed the changes rippling across Vale's being—the sprouting of leathery wings, the crimson hue of his skin, and the intense glow in his eyes. She could feel the surge of demonic energy emanating from his transformed form!

'No wonder he asked me to knock him out if he went out of control...' Yvaine mused.

She remained vigilant, ready to intervene if the transformation veered toward danger. Her ethereal form pulsed with a protective aura, her connection with Vale growing stronger as she prepared to fulfill her duty as his guardian.

As the transformation neared its completion, Yvaine felt a sense of relief.

Vale had successfully assumed the form of an Imp, his aura pulsating with newfound power.

"Are you still Vale?" Yvaine asked the creature in front of him.

"Keek..." The Imp made some noise.

It seems there was a problem with his throat, and he couldn't properly speak.

Realizing this, Vale reassured Yvaine by nodding his tiny head and speaking through their unique connection.

'I'm fine, Yvaine... Thank you for guarding me. I think this creature has a problem as it can't speak.'n0vElUsb.c0m

'I understand.' Yvaine replied as she hovered around Vale.

In the meantime, Vale also marveled at his new Imp form. He could tell that the aura that was pulsating from his body was the essence he had Extracted from the Undead Imps...

"Let's see..." Vale muttered as he entered his Phantasm State.

It feels different.

With his transformation complete, he could feel the Imp's instincts coursing through him. He couldn't properly describe it, but he could sense the world in a different way.

'Oh... I can also use the Imp's Spells?!' Vale's eyes lit up as he realized the changes in his Spell Models.

Unfortunately, he can't use his other Spells aside from the Imp's Spells within the duration of his transformation, but it was completely fine for him.

The Imp's Spell, a dark and potent force, was now at his disposal. He would like to try it!

Grinning mischievously, Vale decided to put his newfound powers to the test.

He checked his four new Spell Lights and found them fascinating. They were Mischief's Veil, Phantasmal Mirage, Ebon Shield, and Nightfall's Embrace.

After he focused his senses on their Spell Models, he was able to understand what they could do.

The Mischief's Veil creates a shroud of illusionary magic that cloaks him in invisibility, allowing him to move silently and undetected through the shadows.

The Phantasmal Mirage summons an illusory duplicate of him, confusing enemies and diverting their attention away from the real target.

The Ebon Shield erects a protective barrier made of dark energy, shielding him from incoming spells and physical assaults.

Lastly, Nightfall's Embrace unleashes a devastating burst of shadow energy, engulfing a large area in darkness and dealing significant damage to all adversaries caught within its radius.

'Aside from the Nightfall's Embrace, all the other three were used by the Imps a while ago.' Vale thought to himself.

Eager to put his new spells to the test, Vale decided to start with Mischief's Veil.

He focused his energy and triggered the Spell Activation.

Soon, he started feeling the cloak of an illusionary spell envelop him. As he moved, he noticed a ripple in the air, hinting at his presence, but it quickly dissipated, leaving him effectively invisible.

Vale marveled at the newfound stealth and freedom he possessed. He could now navigate the chamber undetected, ready to strike at his enemies with precision.

'This looks cool... It's a bit unfortunate that I can't use it in my human form...' Vale thought as he canceled the Spell after 30 seconds or so.

Next, he turned his attention to Phantasmal Mirage.

Concentrating on the Spell, he summoned an illusory duplicate of himself... or to be exact, another Imp version of himself.

The mirage stood beside him, mirroring his movements flawlessly. He couldn't help but feel impressed by the level of detail and realism the Spell provided.

'As expected of an Imp... They're really the masters of illusions. Perhaps only Divine Sense can pierce through this Spell.'

He could imagine how this illusion would confuse and divert his adversaries, creating openings for strategic strikes or providing a crucial distraction when needed.

With a sense of anticipation, Vale then brought forth the power of Ebon Shield. Dark energy swirled around him, forming a protective barrier.

He could feel the shield's strength and resilience, providing him a newfound sense of security. It was quite good against Physical Attacks, but Spells might be its weakness.

'Not as good as my Arcane Armor...' Vale silently thought.

Having practiced with Mischief's Veil, Phantasmal Mirage, and Ebon Shield, Vale felt he could use them six more times before his energy reserves were exhausted.

'It was quite good... Let's try the last Spell then...'

It was finally time to unleash the might of Nightfall's Embrace.

I didn't take long before Vale unleashed Nightfall's Embrace, his surroundings were engulfed in darkness. Shadows danced and writhed, causing a chilling sensation to grip the air.

Then, a burst of energy exploded.

Boom!

It obliterated everything in its path.

The power of the Spell was awe-inspiring, leaving Vale in shock of its destructive potential.
