Man the Psy hunter is a badass, he even blocks brimstone to a certain degree

*Your son has become corrupted by sin. He needs to be saved.*

i love the whole eldritch abomination theming in the enemies and scenery, it gives sheol a LOT more personality instead of just being some dark cave with evil enemies in it plus it fits considering the whole leviathan transformation you can get from having enough "evil" items

I think my favorite part in Sheol are the new psychic enemies. It makes me thing it's what the enemies in Mausoleum are worshipping and gain their powers from

That Psi-Hunter enemy is awesome! I love the variety in their attacks/behavior.

I love how the Psi Hunter almost adds some story to this floor. Like it used to be ruled by demons until the “psionic eye species” took over, and now the Psi Hunters are here to clear them back out. Probably thinking way too into it, but it was a neat little detail.

Gotta love the room names they add,especially that Star Wars reference with psi hunter

I love the idea of this sort of eldritch invasion of Hell, to the point where there are even dedicated demons who work towards fending off psionic creatures. Makes Sheol just that much more interesting!!

<a href="#" class="seekto" data-time="350">5:50</a> *”IT SHOULD’VE BEEN ME! NOT HIM! IT’S NOT FAIR!”*

I love the Psionic Knight….would make a VERY interesting challenge to just have him as your only enemy

Iirc in the original fiend folio mod page, it said that Psion and his kind are in a constant fight with the sheol inhabitants for domination, basically being an invasive kingdom. This is the reason why Psion can almost always appear as a mini boss in sheol.

Isaac did WHAT in Europe?

Loving the Psion themes, giving it a feeling of all those evil monsters isaac learned from D&D, taking inspiration from the beholder. Makes the whole place feel like an ancient, eldritch plane rather than dark cave #3

There were so many new cool enemies you didn’t show because they were added after your videos about them. I’d love to see regular update videos about the new enemies after this main series ends. I love these videos.

The theme of this level seems to be "have fun dodging these, you son of a jerk".

I like that most of the floor narrates a turf war of sorts between Psion and Satan

I thought for a second the Psi-hunter would be so unbalanced in room with many enemies, but once I saw him go against other enemies? Changed my mind on that one Really cool mod so far, I won't play it cause I'm too bad at mod Isaac, but it really looks good

that skywalker room is genious, did give me a good laugh

The floor patterns seem to be a nod to Gyigas I'd imagine.

the world truly needed one more "weak point facing away" enemy

WOOP WOOP THATS THE SOUND OF THE POLICE WOOP WOOP THATS THE SOUND THAT I NEED

I appreciate the fact they fleshed out the cathedral and sheol so much because at that point they basically have no presence due to the fact you harass through so hard, i wish they had given the chest and dark room the same treatment though

It's very interesting how most areas now have multiple themes. For an example, this one having psionic enemies next to demonic ones.

The psi hunters are really gonna give ness a hard battle

[realizes what the cauldron is for] i always knew butchers knife aides enemies more then it hurts them (unless you have piercing or brimstone then you basically do double damage)

Psi hunter actually attacking psi enemies is a pretty cool feature. The resistance to brimstone it inherits from behaving like the calling card familiar (which seems to be like a mini satan anyway, pretty reasonably showing its brimstone resistance) is also a really neat and unique interaction for an enemy.

The sound design on the Psionic enemies are exquisite. So weird but satisfying.

Psi Hunter has so many cool rooms where they slay tons of psi enemies in funny ways! I wish I could have shown more but that would miss the point of the video 😅Such a menace!

I love how psi hunter hunts well, the psilings since they are invaders after all (basically the story is that psilings are all from another dimension and want to take over sheol)

I am down bad for Ms. Dominator.

i love the theme of the psy enemies, their alien appearance and the fact that the psy hunter exists tells a story by itself, of a weird lovecraftian lifeform (the psion) that has invaded the sheol and satan's forces actively trying to repell it. when it comes down to it they are both evil so of course both still very much attack isaac regardless

Psi hunter’s pretty unwily for a foe, killing practically everyone in the room before Isaac. Plus, that spin-slash and defence against brimstone is pretty crafty!

The Psi Knight seems like a cool concept, because I think enemies attacking other enemies could be a cool concept, and could imply that not everything is specifically out to get you. Also I could imagine a concept where it has a chance to appear in rooms where it shouldn't be, like jumping out of a secret room to attack everything. (or maybe an item that spawns one of them to help you?)

Thank god Skay changed the video title lmfao. (The old title was, “Isaac Gets Dominated” I believe, I may be wrong.

Loved the room name "Master Skywalker, what are we goi mg to do?" for the psyhunter + psyeggs

<a href="#" class="seekto" data-time="2">0:02</a> IT’S THE NUTSHACK

<a href="#" class="seekto" data-time="230">3:50</a> holy FUCK that room name lmao

"Welcome to the shadow realm, Isaac." -T Judas, 2022, before initiating a dual with a brimstone hunter.

"Isaac Gets Dominated!"-Past Slay

I love when you post videos like this, keep up the good streak

The dynamic between Psi enemies and Psi hunters, and the feeling of war between the two, is nice.

I have an idea, make the eyes on the walls follow where ever you go, giving Sheol a even more creepy vibe

my favorite thing about the fiend folio sheol is the redesign of the walls and flooring. i cannot STAND how dark it is in the base sheol. i cant see anything, it's like curse of darkness permanently without the little aura of light around isaac. i play with low screen brightness due to health issues a bright screen causes me and i literally get discouraged from going dark room because of how daunting the level design of sheol is on the eyes

<a href="#" class="seekto" data-time="432">7:12</a> this 'sombra' enemy reminds me of the 6th boss from the Flash Game called "Legend of Johnny", literally the same concept, but it gets paralyzed when it's exposed to any source of light.

Ah yes, my favorite enemy. The dommy

Memes aside, Ms. Dominator actually seems like a fun little Miniboss, focusing on Minion Management, but obviously not having more than a Chain Ball and 2 Minions at any given time.

Isaac was a sub all along

Really liking the sound design on this floor

Fun fact: Psi hunter hits the Griddy after successfully killing issac

<a href="#" class="seekto" data-time="240">4:00</a> nice star wars reference xD

I love that teleport sound effect

aww hell nah they made a dommy mommy isaac enemy 💀

I love the noise the psiling makes when it shoots Boing

Excelsior soundtrack really bops!

it almost looks like sheol is overrun with the eldritch psi monsters, and the native denizens either hunt them or otherwise want them gone

about to become Mr Domnimater

At this point it's not just that the enemies in the floor have dynamics and cooperate with one another, it's become a full on ecosystem complete with native predators that hunt down both the player and other enemies. It kind of reminds me of the Harvest Sphere in the first Prey

Isaac got some unwise thoughts

🤨📸 Edit:He changed the title...good... That tioe of heresy cannot be allowded

Oh my. What a thing to show up on my notifications bar, lol.

Lol, imaging call Ms. Dominator Dominatrix

Boys, get the guns! We’re heading to SHEOL!

Think what i like about these enemies is the fsct they arent just all attack you only enemies. They have interactions and the whack a worm actually has a trail of where it is at instead of teleporting allover the place.

Issac has truly become corrupted by sin.

Psi Hunter reminds me of Johnny easter egg in Minecraft.

I love how the psi hunter just straight up doesn’t care and even goes to kill other enemies

I know that psychic powers and domination are the themes of this level, but somehow it also feels like a mishmash of ideas?

Psy Hunter fr looks like a opponent worthy enough to even lay a finger on doomguy

"Master Skywalker, what are we going to do?" 💀

The observer room reminded me of this Splatoon 3 level called "Uh-oh! Too many Snipers!"

psi hunter has more potential than my expectations expected

I knew she'd be in the thumbnail.

<a href="#" class="seekto" data-time="228">3:48</a> That room name and lay out 💀💀💀

<a href="#" class="seekto" data-time="351">5:51</a> has anyone noticed how silly her face is when she throws the ball?

"Isaac gets dominated!" Is a bit of a sus title there my guy Edit: okay good he changed it lmao

The ms dominator look more like an boss than a simple enemy

Funny sounds :)

Thank you for changing the video title.

Fiend Folio Figments: Figuring out what each FF Floor represents in Isaac’s mind (because I’m bored) Isaac knows about hell, that much is obvious. But what happens when he hears about something eldritch? Maybe at his local library? Uh oh! Idea clash!! “If these exist, where are they now? In hell? Are they what demons really are? I don’t know! They seem like it! I’m so confused!!” That’s what this is. Considering there is at least 4 interpretations of Hell in this game, I imagine Isaac has no fucking idea what it is or what’s in it and had to come up with things himself, and thus got sent into a spiral on which interpretation is real like his imagination somehow lost the script.

The psyeggs should be larger. They're awkwardly just a little smaller than a block.

"Master Skywalker, what are we going to do?" DeStRoY the ChIlD

Loving these thumbnails and titles!

Isaac exists.

who else noticed that the sound of the psi hunter swinging his sword is the same sound thats used in tf2 when the half zatoichi is swung? just me? ok.

Oooh, it’s the Psi HUNTER because it hunts down PSYCHIC creatures! Cool!!

Good job.

the foreseers use the same clap sound effect as the default dance in fortnite and it annoys me so much

Umbras are cute! When they fuse they wave at the one they fused to😭

I see the Psi Hunter subscribes to the “kill anything that breathes” lifestyle

FF devs did a really good job as usual.

I do really like the whole difference between the demonic and the eldritch in this floor. Is like these creatures are invading satan's domain so he made the Psi Hunters to deal with them.

I like this more fantasy-like Sheol.

I swear to Arceus itself, to design this floor and its enemies they resurrected H.P. Lovecraft and asked for his advice

The music gives me really heavy madness combat vibes

Can the Thrall deal damage to you when invisible?

Speaking Of Sins, can you post the OST for the glacier sins? I can't find it anywhere.

Music so cool

Nah they did my boy eyesack dirty
