"Besides that, there are some Heroic Spirits unrelated to me."
From Artoria's description, Damien understood she meant those who weren't King Arthur but shared her appearance.
Fate series enthusiasts had a term for them... Saber faces.
"Not just variants of King Arthur, but even Heroic Spirits who look similar can be summoned."
"Tch, this skill is pretty insane."
Artoria felt a bit shy at Damien's praise.
Thankfully, he didn't ask her to demonstrate it.
Otherwise, she might have died of embarrassment.
Cosplay was one thing.
But twin sisters? That was far too bizarre for the conservative Artoria to handle.
"Ahem."
"Alright, I'll stop teasing."
Damien mused, "Let's talk about 'Isolated Legacy.'"
"From the description, it's derived from Avalon's scabbard, right?"
"Yes."
Artoria agreed, finding the skill ridiculously overpowered, "Isolated Legacy means I'm permanently under the scabbard's protection."
"It greatly boosts my immunity and resistance."
As for how much, it was hard to quantify, but it was substantial.
"It also makes me immune to any lethal effects from non-Ultimate Skills."
"What does that mean?"
"To kill you, it has to be an Ultimate Skill?"
"Exactly."
"Only an Ultimate Skill can cause crippling or fatal damage to me."
"..."
Damien was speechless.
He wanted to rant that the Voice of the World must have pulled this skill out of nowhere.
It was absurd!
With this skill, Artoria, as a Hero, effectively ignored all threats except the Seven True Demon Lords.
"Good thing you're on our side."
Damien couldn't imagine what this skill would become if it evolved into an Ultimate Skill.
An unbreakable defense was one thing.
Even if breached, non-Ultimate Skills couldn't kill her.
And with Avalon's protection, any non-lethal injuries would heal quickly.
No more lingering curses like those from Gáe Buidhe.
"Hiss..."
The more Damien thought, the more he sensed malice from the Voice of the World.
This skill felt like the Cardinal World's attempt to counter Majins and Daemons for its own survival.
But, thanks to Violet, this powerful Hero template ended up under Damien's command.
A bug-level Hero working for a Demon Lord.
What a cosmic joke.
"I feel like no matter what crazy skill you get next, I won't be surprised."
Damien turned to her final skill, "Holy Sword of Promised Victory - Thirteen Restraints."
"Is this the one I'm thinking of?"
The strongest and most majestic holy sword, the Holy Sword of Promised Victory.
Forged by faeries to combat Velber, it was the ultimate world-saving weapon.
Capable of splitting a planet with its terrifying power.
If it can split a planet in Nasuverse, then here...
After careful questioning, Damien learned that unleashing the sword's restraints was incredibly difficult.
Its power couldn't be used for conquest or aggression.
Only in defense against invasion could it shine.
The more desperate the situation, the greater its strength.
If all thirteen restraints were released, Artoria could channel the power of all her allies into an unimaginable strike.
But the Holy Sword wasn't just her power... it was Damien's too.
Thus, its activation required his permission.
In a way, this nuclear weapon was in Damien's control.
"It feels like a trump card for a desperate comeback."
Damien noted that the Holy Sword didn't fall under general, extra, exclusive, or Ultimate Skill categories.
It was a skill that grew with its wielder.
Even if Artoria gained an Ultimate Skill in the future, the Holy Sword's amplification would stack atop it.
This was similar to the Ring of Divine and Command Spells.
So, special skills and unique skills are essentially the same.
The difference is one can be shared, while the other is exclusive to one person.
Magicule Solidification, Ring of Divine, Command Spells, Holy Sword of Promised Victory.
Rather than belonging to a skill tier, they were percentage-based support skills.
"Violet."
Damien connected with Violet, asking about the Holy Sword's limits, "If Artoria awakens as a True Demon Lord and unleashes all thirteen restraints, how strong would it be?"
[World-ending]
"..."
What could Damien say?
Releasing all thirteen restraints meant his side was in an irreparable crisis.
Not only would their base be destroyed, but Damien himself might be near death.
Facing such an enemy, Artoria delivering a world-saving strike made sense, right?
Also, world-ending wasn't that big a deal.
In the original story, Milim and Guy's battle would have destroyed the world if not for Ramiris's intervention.
"Special A-rank magicules, three exclusive skills, two bug-level abilities."
Damien didn't know how to evaluate it, only that Artoria was qualified for his top tier.
He also noticed one detail.
[Acquired new data: 'Heroic Spirit,' integrated with Cardinal World concepts of Elemental, Daemon, and Angel]
[Integration successful. New race created: 'Holy Spirit']
"Holy Spirit?"
A new race alone wouldn't faze Damien.
But the description was peculiar.
In the Cardinal World, spiritual lifeforms were mainly elementals, daemons, and angels.
Artoria's arrival introduced a new category... Holy Spirit.
Not Heroic Spirits, but a new race born from Nasuverse Heroic Spirits fused with the Voice of the World's rules.
