Fate/Magus Path

147 Marble Phantasm

On the rooftop, staring at Roa, who was gleefully darting about, Arcueid was starting to grow impatient.

She didn't have the luxury of wasting time on him... this needed to end quickly.

Suddenly, she recalled Roy's earlier advice about her combat style. A glimmer of realization flashed in her eyes. With a sweeping motion of her hands, she gathered her magical energy and materialized numerous bizarrely shaped blades around her, hurling them toward Roa in an unrelenting torrent.

"You're overflowing with magical energy. Focusing purely on brute force is a waste of your unique abilities."

These words were Roy's critique.

"Try to understand your unique potential... perceive its essence and transformation."

"Analyze. Reconstruct. Manifest. Go on, create something entirely new."

The echoes of his guidance replayed in her mind. Roy attempted to push her toward realizing her full potential.

When Roy first witnessed Arcueid's absurdly straightforward combat style, he was practically driven mad with frustration. Even though he knew her intellect wasn't her strong suit, he hadn't expected her to squander such extraordinary talent so carelessly.

After all, Arcueid's ability, Marble Phantasm, was one of the most absurd and powerful in existence, even within the context of the moonlit world.

It was no less formidable than Roy's Heaven's Feel or Zelretch's Kaleidoscope.

But in her hands, this miraculous ability was almost entirely neglected, used passively at best.

Marble Phantasm, as the name suggests, is a unique power inherent to her as a nature-aligned spirit. It connects her will to the world itself, allowing her to alter reality in accordance with her imagination.

In simpler terms, it enables her to manifest objects she visualizes in her mind, creating something out of nothing.

For comparison, Emiya Shirou's projection magic relies on replicating weapons based on their legendary origins, producing imitations. This is why Gilgamesh disdainfully refers to them as fakes. However, anything manifested through Arcueid's Marble Phantasm would be so authentic that even Gilgamesh couldn't label it a forgery.

This power is utterly broken, on par with the most revered True Magic. Armed with sufficient knowledge of legendary armaments, she could conjure divine constructs tailored to counter any opponent, no matter the situation.

Yet such an incredible ability was almost forgotten by this golden-haired simpleton, wasted as she recklessly relied on brute strength alone.

After defeating Nrvnqsr Chaos, Roy had taken it upon himself to tutor her in how to properly utilize her overpowered skill.

Using Gilgamesh's combat style as a teaching template, he guided Arcueid toward emulating the King of Heroes' tactics.

If a quick melee kill with her claw strike worked, that was ideal.

But if faced with a persistent and troublesome foe, she should fully exploit her Marble Phantasm to summon weapons that counter her opponent's strengths. From there, she could overwhelm them with a constant barrage of weaponized destruction.

The strategy revolved around targeted weapon deployment, long-range attrition, and exploiting openings to deliver a decisive blow.

And so, faced with a rain of Black Keys and specialized anti-demon weapons made from enchanted mithril, Roa found himself utterly stunned.
