An optimized application with Repentogon for better performance when used with other mods, and it will be even more godlike than it already is.

works on latest repentance + without repentogon, absolutely insanely well made mod, congrats!!

why i dont see my heart pls help

Half of the rooms in basement are so Mind Bogglingly Challenging, it almost feels ridiculous to walk into a Fiend Folio room and fight enemies that feel like depths/womb level enemies, then right back into a normal Isaac room like nothing happened.

it makes starting a run such an uphill fight, and even though I don't do it, I feel I'm wasting my time not just holding R and resetting for an early Quality 3 or 4 item from a treasure or curse room.

The floor 1 bosses are mob spawning machines with projectiles, area effects, and the whole 9 yards. I almost feel relieved to see ragman.

Some of the enemies on the actual post depths floors are the absolute epitome of skill checks requiring some heavy memorization of a mod boasting over 500 new monsters.

It's almost a shame because I like all the enemy ideas, designs, and art but the room layouts are so abysmally tuned.

how to noob?

Note: i had to delete the file, but when i put the mods back again, the savefile continues to crash.

During the fight with cacophobia i was using the keeper, then the game crashed after i died and corrupted my savefile, making it impossible to open and crashing the game.

mod is too easy. make it harder pls?

Is China an upcoming character? You might wanna do something about the Horse Push-Pop spawning regardless who I'm playing.

bro what (ms 37) [ MOD ms 1023] your not Fiend Folio Reheated; bette now

крутой мод

wonder if this will work unupdated since RGON just got REP+ support...

muito bom mod mas não funciona com o mod do personagem andromeda, daria pra fazer o mod funcionar com ele?

я пукнул

i have a visual bug where curse of the unknown shows that i have 4 diffrent holy mantles, and when i have diffrent holy mantle like the one from holy card when used instead of it having the visual of holy card holy mantle it has the normal one

not entirly sure if its this mod since i can't see all the mod's enemies but there is an enemy in the corpse map which fills out gaps in the floor, the issue with that is it softlocks you, killing them does not open the room and ruins the run

I feel like Fient would make a good challenge character.

Also how best to support your work, in the rep+ etc update?

Amazing content, but the performance is abysmal at points. The CPU gets throttled somehow, the FPS drops to 20 or 10 even at places.

good mod

is this mod will ever get optimized so it won't get laggy?

cacophobia made me ♥♥♥♥ my pants 10/10

Boss rush wave counter for one.

so which type of mods wouldn't be compatible with this one?

Im not sure why but in the last couple days, i've had the small 'Smidgen' enemies stop attacking me, which makes them pretty much invincible unless i happen to have spare bombs on me

Heya. Why don't any of the Fly enemies become Friendly when I have the Beelzebub transformation? The only reason I noticed this was because I was throwing my head against the wall trying to beat Solar System with this mod installed, but it's still getting on my nerves.

one of the best Isaac mods, period
just one massive issue, it gets laggy fast, especially when running it along other big mods
crossing fingers for the upcoming massive update to fix that

any chance we can get a standalone version that only adds the items?

too much laggy ç_ç

removing the item from the files fixes it i guess

theres a glitch with tmtrainer where if empty book is used in a tmtrainer item it softlocks you, plz fix

I love how much more variety and challenge the mod adds to the game, and there's some really cool ideas present as well
The only thing truly holding the mod back is the performance tax. I hope Reloaded, above all else, optimizes the code a bit
Otherwise, mod is cool and goode

frog guy knows whats up

Waaaaaaay too ambitious for its own good. There are tons of really cool ideas and enemies but there is borderline zero tuning. There are rooms that feel like classic rebirth, there are some that are a little difficult but fair and then there are rooms that destroy half my health and have me going "How is this on Caves 1???".
I really wish I could have a version that cuts out anything that doesn't benefit the game as a whole. That is more for a selling product tho, it's basically impossible for a modding team to kill their darlings...

The settings I change in the dead sea scrolls menu return to default upon restarting the game! How can I make them save, does anyone know?

does this work with rep+ ?

I'm getting a visual bug where enemies like the Bowler (and Striker / Striker Ball), when the bowler throws its head, the head sprite glitches up and down (visually) while moving, but stops glitching when it stops. With the Peak-A-Boo, when its eye comes out, same thing happens. Can someone help me?

id argue the consistency case in a different way. @penguin take for example poops and fireplaces in base game. theyre distinctly different and there are floors that replace either or. burning basement for example, as far as im concerned, replaces poops upon spawn with fireplaces. you wont see poop natively spawn there. try treating beehives similarly as a new obstacle.

no offense but what are you doing complaining about having to relearn things on a overhaul mod it’s literally gigantic and
changes up most of the gameplay of course you’ll have to relearn things isn’t that the point? I know there is a lot of content mods but with the amount of enemies and new room layouts you’ll have trouble if you don't relearn and the whole point of the mod is to make all the floors feel different and play different you just gotta learn them individually that’s the cost of the mod I guess

so, I tried this mod recently, and I'm uninstalling for one reason specifically, that being that poop and rocks seem to be changed into completely different objects in each area?
The only issue I have w this is, well, two things actually, one is that it kinda makes me need to relearn each area from scratch, as I no longer know what each piece does or how it interacts with any other, if I have a poop related item, do beehives trigger that for example? I feel like they shouldn't, but the area seems to have no other poop like items around so they must right?
my other issue is that with the other thing, it also makes me unsure of even the most basic question of "can this be destroyed by a bomb?" I have tried to bomb things I thought were bombable multiple times to no avail, lol ndfkdnsjkfs

but yeah, just thought I'd post in whatever this is as feedback or something, idk

on the positive side, the section in the options for "tracking" was utterly hilarous lmao

why the hell my health containers became invisible????????

laggy ass mod, ♥♥♥♥♥♥♥♥ optimized

The BEST content mod for Isaac.
Excellent sprites of EVERYTHING in the game, and better in combination with Meep's Monster Resprite mod. A lot of content to explore, waiting for next update

Works without problems on Repentance+
I hate fcking Meltdown boss (skill issue)

idea mod legendary monsters

mucho lag ff

repentance + isn't yet compatible with huge mods like this one, so expect not to work or constant crashes untill the people working on the game come up with a stable version of repentance + and when modders will bi able to come with a version for that.

crashes in the new version :)

wish there was a standalone mod that only added the fiend folio items, the main fiend folio seems to overwrite my other reskin mods

so good

i imagine i'm the first person in the entire world to ever have had this issue, but i took Shard of Glass and used the tarot that gives you key shots in exchange for costing keys to fire, and every single shard of glass blood tear drains a key making it functionally impossible to actually gain them back, likely just an oversight
