A Blade Fiend's Fathoms is the Story Dungeon of Intervallo III: Yield My Flesh to Claim Their Bones, and the second Dungeon to be tied to an event.

Overview

A Blade Fiend's Fathoms essentially works like a one-floor Mirror Dungeon with 7 nodes, a Shop node, a Rest node, and then the final boss node vs Distorted Bamboo-hatted Kim.

Enemies

Encounters in A Blade Fiend's Fathoms comprise of enemies encountered throughout the rest of Intervallo III-2. Specifically,

• Normal Encounters consist of Kurokumo Clan Henchmen.
• Elite Encounters consist of battles against Kurokumo Clan Captain Jun alongside some Henchmen.
• Focused Encounters consist of battles against Peccatulum Irae? and Peccatulum Morositatis?, as well as their Stage 1 counterparts.

The final node always consists of a battle against Distorted Bamboo-hatted Kim.

"It's us Kurokumo Clan's turf from here on out."
"Is it that hard for you to understand that you gotta pay the toll to use our road? Huh?"
People dressed in Kurokumo Clan garb stand in the way of unarmed civilians, threatening them.
"... I suppose that excuse was enough for them to tread on our territory as well."
Aeng-du does not hide her indignation. She is gritting her teeth.
What should we do about them?

Save the civilians. Gain a Keywordless E.G.O Gift depending on the result of the following choice Who will step forth? Wrath / Sloth Advantage: ≥ 9 No Advantage: ≥ 18 Check Passed "Damn it..." "What the hell happened?! I thought we'd driven them all away!" After a grueling battle, [Sinner] and Aeng-du managed to defeat or drive away the Kurokumo Clan henchmen. "... You have my gratitude. I'm glad that we could provide them some help." The selected Sinner heals 30 SP Check Failed "Damn it..." "What the hell happened?! I thought we'd driven them all away!" After a grueling battle, [Sinner] and Aeng-du managed to defeat or drive away the Kurokumo Clan henchmen. But... "... Ach." Perhaps Aeng-du hadn't fully recovered yet. She ended up suffering some damage from the skirmish. [Sinner] also seems to have taken some hits while protecting wounded Aeng-du. "My apologies..." Aeng-du muttered through gritted teeth. There was a tinge of shame in her voice. The selected Sinner took 30 HP damage "Thank you, thank you so much..." The civilians, freed from the threat of the Kurokumo Clan, each bow and give us their thanks. "But... You're not dressed like a local." "If you don't mind us prying... who might you be?"

Say that you're just passing by. "Huhh...?" The civilians appear puzzled. "You're just... 'passing by' with this many people behind you?" Maybe I should've given my answer more thought before replying... "Why would you help us if you don't have anything to do with the Kurokumo Clan...?" They looked at each other, clearly perplexed. "T-thank you anyways." "Sa-safe travels to you!" With that, they hurriedly left the scene. Nothing Happened.

Say that you're with the Blade Lineage. Pride Advantage check. Pass to gain a Keywordless E.G.O Gift. Who will step forth and speak? Pride Advantage: ≥ 12 No Advantage: ≥ 24 Special Check Identity-Blade Lineage Identities Check Value +5 Check Passed "The Bl-bl-the—" The civilians immediately kneeled before us and bowed profusely. Their voices tremble as they plead. "We're sorry, We're so sorry!" "Please, have mercy... Don't kill us...!" In a flustered attempt, [Sinner] tries to tell them that we have no cause nor intent to hurt them; but they refuse to listen. "T-take this, at least..." They raised their hands with the utmost deference. In their hands was what appeared to be a book. Taking a closer look at it, we realized that what they handed us was a filled ledger with black covers. "Please, forgive us! That's all we have with us at the moment..." Try as we might to help them to their feet, the fear has already rooted them firmly to the ground. They don't even dare to raise their heads. ... We had no choice but to leave them as they were. E.G.O Gift Black Ledger Earned! Check Failed "... That's one nasty joke, fellas~" Maybe [Sinner] sounded awkward when they claimed to be from the Blade Lineage. The civilian's eyebrow twitched for a brief second before he burst into laughter. "Why would they be out here, in these streets?" "Right, right. Besides, why'd they ever help us? We just turned a blind eye when they—" "Hey now! Shh, watch your mouth!" "Ah!" After an exchange none of us had enough context for, they suddenly snapped as though they realized we were still standing right here. "W-well then... Thank you for the help anyway!" "But don't say something like that, even as a joke! You never know what'll happen..." With that, the civilians hurriedly left the scene. This did nothing but bring down our mood, did it... The selected Sinner lost 10 SP

Turn a blind eye. "Another day, another mugging in the City." One of the Sinners mutters with a sigh. "......" Aeng-du stands there with her eyes pleading us to do something, but does not step forward. We should avoid unnecessary battles... ... if we are to survive the coming challenges and face Distorted Bamboo-hatted Kim who awaits us at the end of this path. This left a bad taste in our mouths as we ignored the commotion and walked away. All allies lose 20 SP

Rusted Hilt

"This must be a tavern..."
This bar or an inn is bustling, and its patrons are energetically chattering away. They all seem to be in a rather good mood.
A trio among the crowd is quite boisterously arguing and pointing fingers at each other.
"No, NO! I don't understand why this is even a matter of dispute! A blade is a weapon made for cutting, and the 'right' way to use a blade is to slash with it."
"You don't know what you're talking about! Stab a single point with all your might, and your foe shall surely fall!"
"... You're both wrong. Your half-hearted cuts and stabs won't do anything but piss 'em off. They'll be back on their feet immediately!"
"Smack their skulls with the blunt end—hilt or the scabbard, and knock them down for good! Make 'em too dazed to get up!"
The trio appeared to be talking about something pretty serious, so we'd stopped to listen to their debate...
They suddenly turned in our direction and called over to us.
"You there! Your band can clearly handle your weapons, am I wrong?"
"Answer us. What is the best way to wield your sword?"
"Of course, to slash is the best way to use a blade, is it not?"
What should I say to that?

Right. Slashing is the way to go when wielding a blade. Lust & Pride Advantage check. Pass to gain a Slash E.G.O Gift. Who will share their opinion? Lust / Pride Advantage: ≥ 14 No Advantage: ≥ 28 Special Check Identity-Kurokumo Clan or Blade Lineage Identities Check Value +7 Check Passed "Hear, hear!" The loudest one guffaws, raising his cup full of liquor. "I'm not claiming that other methods are inferior! I am merely claiming that a blade, a weapon with an edge, is made to cut things!" The other two nod in reluctant agreement. "W-well, if you're talking about the blade and the blade part only, sure..." "I suppose a decapitation is not so different from breaking the skull open." "Ha! You've made my day, friend. Here, take this!" The man who preached the superiority of Slash pats you on the back and places something in your hands. E.G.O Gift Rusted Hilt Earned! Check Failed "Hear, hear!" The loudest one guffaws, raising his cup full of liquor. "Yet..." All of a sudden, he stops laughing. Then, with a terrifying look on his face, he glares at [Sinner]. "How can you, as a practitioner of the martial arts yourself, deceive yourself and refuse to tell me your true beliefs? Have you no shame?" "Give it a rest, man! Trying to scare innocent passersby again?" The two drinking buddies of the man drag [Sinner] to their table with a giddy look on their faces. "I'm sure the allure of a powerful, singular Piercing strike was too much to deny! I understand, I do!" "The feeling of a Blunt object striking and cracking open a skull... can't get enough of that, eh?" The pair cheered [Sinner] on and filled their cup with liquor. The selected Sinner heals 30 HP

Not true. Slash, Pierce, and Blunt all have their uses. "Hm." The three of them suddenly grow very obviously uncomfortable. "That's the right answer, isn't it?" "That's certainly the textbook answer." "It's not like we don't know what the right answer is..." They all take frustrated swigs from their respective cups. "What, you think we're sitting here talking about weapons like generals preparing for war?" "It's just a fun topic to argue about with liquor in our bellies. What a way to kill the mood with that uninspired answer..." "Bah, forget it. Be on your way, then!" They turned away from us and returned to drinking, clearly having lost interest. Nothing Happened.

Fractured & Broken Blade

"This is odd... this mist is..."
I don't know when it happened, but a thick layer of mist had descended all around us.
"I have heard a tale of one such nightly stroll. In this tale, a clueless traveler heedlessly wanders into a brumous haze, and finds himself afore an otherworldly being—"
"AAAGH! Stop, stop it!"
Just as the Sinners began loudly bickering with each other, I realized that there was something hazy standing in our way.
"Is that thing... dancing?"
A mysterious thing, dressed in white, danced gracefully before us with a large blade in hand.
When it met my gaze... or, when I thought it did...
... a sheathed blade had materialized in my hand.
What does it want me to do with it?

Assume a stance like I'm about to draw the sword. Lust & Gloom Advantage check. Pass to gain a Bleed E.G.O Gift. Who should wield the sword? Lust / Gloom Advantage: ≥ 16 No Advantage: ≥ 32 Special Check Identity-Kurokumo Clan Identities Check Value +7 Check Passed [Sinner] wielded the sword. "...!" After taking a moment to steady their breathing, [Sinner] unsheathed the blade and sliced the thing before us in the blink of an eye. That thing giggled as it disappeared, somehow finding this situation humorous... And left behind fragments of a blade. E.G.O Gift Fractured Blade Earned! Check Failed [Sinner] wielded the sword. "...!" After taking a moment to steady their breathing, [Sinner] unshea— —Nevermind. They failed to unsheathe the blade, and instead dropped it to the floor. ... I think they were holding the sword backwards, slicing their own palm open in the process. The thing disappeared while we were busy trying to stop the bleeding from [Sinner]'s hand. The selected Sinner took 20 HP and SP damage

Unsheathe the sword and hold it on my side. Pride & Wrath Advantage check. Pass to gain a Poise E.G.O Gift. Who should wield the sword? Pride / Wrath Advantage: ≥ 16 No Advantage: ≥ 32 Special Check Identity-Blade Lineage Identities Check Value +7 Check Passed [Sinner] wielded the sword. "......" [Sinner] effortlessly unsheathed the sword, threw the scabbard away, and gently lowered it to their side, its tip pointing toward the ground. That thing giggled as it disappeared, somehow finding this situation humorous... And left behind a broken blade. E.G.O Gift Broken Blade Earned! Check Failed [Sinner] wielded the sword. "......" [Sinner] carefully and effortlessly unsheathed the swor— —Nevermind. They failed to unsheathe the blade, and instead dropped it to the floor. ... I think they were holding the sword backwards, slicing their own palm open in the process. The thing disappeared while we were busy trying to stop the bleeding from [Sinner]'s hand. The selected Sinner took 20 HP and SP damage

Leave the sword, let's leave. It's not an Abnormality we have to deal with, and the company never said that we had to engage them. I should always avoid battles against unknown entities. I tossed the sword on the ground before fleeing from the scene with the Sinners. A weeping laughter seemed to follow me the entire way back. All allies lose 10 SP

Red Tassel

We hear a pair of voices as we walk alongside a stone fence. The two travelers are both carrying blades.
"I pity the people here..."
"Well, the decision of a Wing is absolute for its feathers. There is very little they can do about it."
One of them stands out—their clothing sets them apart from the locals. Maybe they're not from around here.
"Still, to allow the Kurokumo Clan to make their way in here? That's too much."
"The Wing cares about naught else but fluttering its wings. All else becomes insignificant."
Sounds like they're talking about the current S Corp.
"More outsiders, I see. How convenient."
The pair stops in their tracks, then turns around to face us.
"The Kurokumo Clan... no. You do not wear their garb. You don't appear to be peasants seeking to make some cash in the chaos of the Backstreets, either..."
"Well, then. What do you outsiders think of the current climate?"
How should I answer this?

It's the City. That's just what happens to small fries getting mixed up in large-scale conflicts. Gloom & Pride Advantage check. Pass to gain a Slash E.G.O Gift. Who will share their opinion? Gloom / Pride Advantage: ≥ 12 No Advantage: ≥ 24 Check Passed "Hah!" The sword-carrying man snickers. "You answer with wisdom to my foolish query. Such musings hold very little significance in the City, indeed." He laughs a little more, this time with gusto, then tears a tassel from his weapon before handing it over. "I enjoyed your answer. If you evern find yourself in a conflict with the Blade Lineage, show them this tassel." "It will be of some help to you, I can guarantee you that." With that, they waved their hands and disappeared into the other direction. E.G.O Gift Red Tassel Earned! Check Failed "True words indeed." They both nod. "But I don't suppose you are wise or capable enough to speak such wisdom from your heart." The two smile awkwardly before turning around and leaving. Left all alone, [Sinner] looked down to the ground with a sad look on their face. The selected Sinner loses 20 SP

I have no thoughts regarding the matter. A pity, though. "A pity, you say..." The sword-carrying man crosses his arms, then sighs. "Sure, I suppose that's one way of looking at it. A thought must remain free, indeed." "Yet, if you have no thoughts regarding the matter, do understand that to feel pity may be a sin of its own." The pair walks away. They both wear a dark expression. Nothing Happened.

Bamboo Hat & Dopo Robe

Shimmering blue letters float before you.
The way that these similar words are ordered makes it difficult to understand what it's trying to say.
To say what is right is right and what is wrong is wrong is not right,
but that is not to say that to say what is wrong is right and right is wrong is wrong.
To say that what is wrong is right and right is wrong is not wrong,
and to say that what is right is right and what is wrong is wrong is, in turn, to say that this wrong is right.
... Does it want my impression of these words?
What is it talking about?

What is 'right' and what is 'wrong'... is it really that important to tell which is which? Say that what really matters is something else. Lust & Pride Advantage check.

Check Failed The blue letters slowly fade away, and a new word appears in their place. 'Wrath.' The word stays there for a moment before burning up and fading away. ... Maybe it didn't like our answer? Nothing Happened.

Still, it must be said that what is right, is right. Gloom & Pride Advantage check. Pass to gain a Slash E.G.O Gift. Who will speak?

Trivia

• The Abnormality in the Fractured & Broken Blade event is the first unnamed Abnormality to be encountered.
