A Blade Fiend's Fathoms
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 works like a one-Floor Mirror Dungeon, with an initial fixed event node, seven (7) nodes that alternate between Combat Encounters and Dungeon Events, another fixed event node for fusing E.G.O Gifts, and a final Boss node against Distorted Bamboo-hatted Kim. Notably, there is no Shop node.
The Dungeon also includes a Hard Difficulty, added for Yield My Flesh to Claim Their Bones' Bokgak Event. The Hard Difficulty Dungeon functions almost identically to the Normal Difficulty version, but with battles against lvl 50 enemies with altered Skills, and additional Hard Difficulty-exclusive E.G.O Gifts and Choice Events.
Enemies
Encounters in A Blade Fiend's Fathoms comprise of enemies encountered throughout the rest of Intervallo III-2.
- 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.

Black Ledger
"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?
"Damn it..." The selected Sinner heals 30 SP "Damn it..." The selected Sinner took 30 HP damage "Thank you, thank you so much..." |
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?
"The Bl-bl-the—" E.G.O Gift Black Ledger obtained! "... That's one nasty joke, fellas~" 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?
"Hear, hear!" E.G.O Gift Rusted Hilt obtained! "Hear, hear!" 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?
[Sinner] wielded the sword. E.G.O Gift Fractured Blade obtained! [Sinner] wielded the sword. 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?
[Sinner] wielded the sword. E.G.O Gift Broken Blade obtained! [Sinner] wielded the sword. 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?
"Hah!" E.G.O Gift Red Tassel obtained! "True words indeed." 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. Pass to gain a Poise E.G.O Gift.
Who will speak?
The blue letters slowly fade away, and a new word appears in their place. E.G.O Gift Ragged Bamboo Hat obtained! The blue letters slowly fade away, and a new word appears in their place. 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?
The blue letters slowly fade away, and a new word appears in their place. E.G.O Gift Old Dopo Robe obtained! The blue letters slowly fade away, and a new word appears in their place. Nothing Happened. |
The semi-final node of the dungeon is guaranteed to be the following event:
'Yield My Flesh to Claim Their Bones' Dungeon Renewal Normal Fusion
We come upon a familiar rest stop.
The glass door is locked, with a notice attached to it.
'We are closed today due to personal reasons. We apologize for the inconvenience.'
'However, our fusion device is available for use. Customers requiring fusion service are kindly asked to use the device beside the entrance.'
What should we do?
Try putting in Rusted Hilt and Fractured Blade. (Only selectable if in possession of the E.G.O Gifts "Rusted Hilt" and "Fractured Blade") After a drawn-out rattling, an E.G.O Gift drops from the device. E.G.O Gift Rusted Hilt destroyed! E.G.O Gift Fractured Blade destroyed! E.G.O Gift Sublimity obtained! |
Try putting in Rusted Hilt and Broken Blade. (Only selectable if in possession of the E.G.O Gifts "Rusted Hilt" and "Broken Blade") After a drawn-out rattling, an E.G.O Gift drops from the device. E.G.O Gift Rusted Hilt destroyed! E.G.O Gift Broken Blade destroyed! E.G.O Gift Unbending obtained! |
There is nothing that seems right to put in the device. We have nothing quite suitable to put in the device. There was no choice but to return to the road. Nothing happened. |
Dungeon Events (Hard Difficulty)
Worn Hilt Choice
"Is this a tavern?"
We walk into what seems to be a bar of sorts, its guests rowdily drinking and chatting about in groups.
We find a seat to relax, but another group that was sitting nearby approaches us.
"What's going on here? I haven't seen your faces around here before…"
"This is a good day, boys—let this one slide. Don't stir up unnecessary trouble."
"Yes, dame! Of course, dame!"
That's when we realize that they're all carrying swords with them.
Swords engraved with elaborate cloud patterns.
"Did you hear about that new Syndicate that sprang up today?"
"Ah, the… the group that primarily uses spears, right…?"
"Dumbasses. Swords are the most superior form of weaponry there is, the apex of arms. And they use spears instead?
"Let's all be completely honest here, guys. Sure, we're a Thumb subsidiary, but there's just something badass about a sword, huh? Way cooler than fists or guns."
"Good thing we have these fine people here to give us a most fair assessment on the superiority of swords.
We feel their gaze simultaneously turning to look at us.
Are swords really all that, though? "Let's put 'em six feet under. Let's go." "Tsk, it's not like we seriously think that swords are actually the best weapons in the world." "Look around ya, see anyone without a sword? Learn to read the room." "Looks like you pissed off my boys. Would it have hurt to pretend to go along with them?" "I think I'll head out now. Remember what I said earlier—don't start trouble and leave them alone." "Yes, dame!" As soon as the person who appeared to be their leader left the room, things became a lot more tense all of a sudden… We quietly and carefully excused ourselves and left the place. Nothing happened. |
Swords are indeed the king of all weapons. Hail! Lust & Pride Advantage check. Pass to gain a Keywordless E.G.O Gift.
Who will speak?
"Now ain't that the truth!" E.G.O Gift Worn Hilt obtained! "The king of weapons, huh? That's cool, but… I think you laid it on a little thick with the compliments." The selected Identity healed for 30 HP! |
Hardwood Liquor Cup Choice
Walking along the stone brick wall, we hear a pair of voices conversing.
"I understand that you've been having some trouble as of late."
"We would not have had any troubles with the tributes if those Blade Lineage bastards had not suddenly appeared in our turf, sir…"
The outfit of one of the pair stands out.
I can hear some of the Sinners recognizing it as the uniform of the Thumb.
"First, exact the appropriate punishment for breaking into your turf…"
"Of course, sir."
"But don't forget to show the right respect for those who deserve it. Am I understood?"
"Wait. Who's there? Is it the Blade Lineage…? Hm, doesn't seem like it."
Noticing our presence, the pair turns around to face us.
"Hm. Why don't we ask for their opinion as well, now that they're here?"
"You there. What are your thoughts on the Kurokumo Clan's current status?"
"Better choose your words carefully."
Unfortunately, war with the Blade Lineage seems to be the only option. Lust & Pride Advantage check. Pass to gain a Keywordless E.G.O Gift.
Who will speak?
"Oh…" E.G.O Gift Hardwood Liquor Cup obtained! "Oh…" The selected Identity took 20 HP damage! |
Wrong place at the wrong time, man. "A regular occurrence in the City." "Why don't we just let 'em go, sir? Doesn't seem like they have anything interesting to contribute." "You heard him. Scram, before we change our minds." Nothing happened. |
