Understandable. We know you have other mods that you've done too.
AgentCucco  [author] 8 Sep, 2022 @ 1:00am 
I'm not sure when/if I will update this mod. Been working tirelessly for a couple of weeks to update a bigger one and I doubt I'll have too much time for unpaid work after that unfortunately.

Both the trinket and the item are broken, maybe you could just remove them and after defeating Librarian, we player will get 2 items of Library item pool as rewards instead.
AgentCucco  [author] 16 Jul, 2022 @ 10:33pm 
I know, not exactly sure why that is when the code should run the chance, but maybe it runs it infinitely until it procs, lol. I made this mod so long ago and I haven't bothered to update it yet.

I'm pretty sure it's 0 because the mod is not ported to Rep like at all. I just tested if it worked, and it worked for the most part but in reality the mod is not supported for rep.
Connor 30 Apr, 2022 @ 12:08pm 
pretty good but the quality of forgotten script should be 2 fits it the best in my opinion
SWE4T & P1XELS 22 Mar, 2022 @ 5:28pm 
I cant wait for this to get ported, such a great mod<3
AgentCucco  [author] 17 Dec, 2021 @ 6:08am 
No, I'm not even sure if it will happen

Is there an approximate release date for 3.0? Just wondering., it's such a great mod
AgentCucco  [author] 6 Nov, 2021 @ 10:19pm 
@Piss Creature They're all documented in one of the videos in this page, though most of the effects don't seem to work in rep.

Mainly asking because I got the damage up book and idk what it did.
Robot Autism 6 Nov, 2021 @ 4:01pm 
Is there a list of what the buffed books/book changes do?
Lolight2 10 Jun, 2021 @ 5:03pm 
Thats good to hear that you are working on another version of it, really looking forward to it as i think you did an amazing job with this boss :)
AgentCucco  [author] 10 Jun, 2021 @ 4:49pm 
I ain't gonna update this mod ever again, I appreciate the bug reports but you are pretty much wasting your time, lol. Version 3.0 would be re-released and being only Rep compatible, being a complete recoding of the boss and items from scratch.
Lolight2 10 Jun, 2021 @ 8:03am 
Crashes the game for me when i collect the item from the boss and use the Satanic Bible active.
AgentCucco  [author] 5 Jun, 2021 @ 6:18am 
Yeh as stated in the description, the mod is unstable on rep, but it works. As for Library Membership, you just got unlucky, I got it in like my second run, lol, but never since though. Most of these issues are to be fixed in version 3.0, but it's still nowhere near finished, just be patient.
Doctor Gumba 5 Jun, 2021 @ 5:53am 
the problem with the 100% spawnrate was already mentioned and all that, but I still have to things. 1. I have never seen the trinket so far anywhere. always got the script wich rarely helped since I had to get a book. 2. Some of the effects that you get are unclear and the one of the Satanic bible I think it wasjust loves to crash the game

I was trying Lost, and this guy, have forced me to restart so many times, my chances on him was like 60/40, mostly cuz I was running to Libary instantly after I got a key
AgentCucco  [author] 30 May, 2021 @ 11:42am 
That's been a bug since Ab+ which I was never able to fix, but in the end I ended up liking it. In 3.0 I might make it a set chance players can tweak, cuz I really liked how I got to fight this dude every first library.
stehchem 30 May, 2021 @ 11:33am 
Looks like boss spawn every times, I had a lot of games with library on first floor and everyone was with boss, bruh
AgentCucco  [author] 30 May, 2021 @ 5:40am 
As stated in the description, the mod is unstable, but it works decently on rep. The Forgotten Scripts don't work all that well, but the boss itself works as it worked in ab+.
NHB 29 May, 2021 @ 9:43pm 
Too many bugs

AgentCucco  [author] 26 May, 2021 @ 12:36am 
Yeah that's planned.
7282727363773 26 May, 2021 @ 12:06am 
If you are doing the 3.0 version, I recommend having it as a mini boss like the sins, since this boss is like the sins in that you enter a locked room to fight it. Just seems like it would fit better.
AgentCucco  [author] 17 May, 2021 @ 2:52am 
Lol, yeah this mod works on Rep but as said in the description, it's unstable. I won't be updating it again, since I'm working on v3.0
Fenirol 17 May, 2021 @ 2:51am 
Co-op is broken
AgentCucco  [author] 15 May, 2021 @ 6:43am 
Hey everyone, I'm here to state that this mod is going to be obsolete in Repentance, I'm just gonna keep it up as a legacy version, but I'll be working on a Librarian 3.0 for repentance with a some tweaks to Forgotten Scripts, way better code and polish, and a few fun extras. It's basically a Librarian rehaul.

So if you are a fan of it, make sure to unsub and be on the lookout for the new version coming in the next couple of weeks, either on the workshop or my socials!
Redstinger665 4 Jan, 2021 @ 12:55pm 
Yay
AgentCucco  [author] 15 Dec, 2020 @ 1:09pm 
Update, I will be updating this mod ever again. There are a couple of bugs that require fixing (mostly regarding Revelations), and also a lot of polishing in the code.

With Repentance in the horizon, I will 100% be doing a version 3.0 which updates the code to be more efficient, and fixes a lot of dumb issues this mod has, once Rep's API update is released.
AgentCucco  [author] 7 Oct, 2020 @ 9:29am 
I will probably not be updating this mod ever again, even version 2.0 was a bit of a stretch to keep the mod alive. I'm more than happy with his current state, if I ever update him, it'd probably be a re-release with more polished code, but don't keep your hopes high.

And no, he has a 25% chance of spawning, maybe I messed something up with the savedata, but it's been a bug since pre 1.0 and I've never been able to pinpoint the issue.
Kefke 7 Oct, 2020 @ 7:43am 
My thought was more having multiple drops unique to him, like Krampus does. Like maybe his other drop could be a special book with a powerful effect.

Also, pretty sure that first library thing is a bug, because it consistently happens to me too. Maybe you had him set to 100% spawn for testing and it didn't get turned off?
AgentCucco  [author] 6 Oct, 2020 @ 4:32pm 
In the beginning he used to drop a random book, on Version 2.0 I made it so he only dropped the Forgotten Scripts. Mainly because he's supposed to be a rare boss (though somehow every always manages to get him on their first library), so a good item drop is warranted in my opinion :P
Kefke 6 Oct, 2020 @ 7:10am 
Really love this mod. However, it would be cool if the Librarian had at least one other drop, so that you aren't sure to always get the same thing.
AgentCucco  [author] 1 Jul, 2020 @ 2:35pm 
I already explained this in the video...
TheSweetDragon 1 Jul, 2020 @ 6:50am 
Thats weird because whenever i use it my stats dont actualy raise
AgentCucco  [author] 30 Jun, 2020 @ 11:12am 
It does work, just test it with SpiderMod or something. It's showcased and detailed in the video.
TheSweetDragon 30 Jun, 2020 @ 7:47am 
So is their a reason when i have the forgotten script item that book of belial just doesn't work with it?

AgentCucco  [author] 27 May, 2020 @ 9:12pm 
About 2-3 years now, you can still see traces of my awful code in the source from back then, lol.
Mr.sandwich 27 May, 2020 @ 9:10pm 
I remember when the boss was just little horn with green eyes. How long ago was that?
Cacat 30 Apr, 2020 @ 4:57am 
:O
AgentCucco  [author] 16 Apr, 2020 @ 2:04pm 
Just you wait
Cacat 16 Apr, 2020 @ 5:08am 
Fair enough, it's just that there's not enough boss mods so I was wondering.
AgentCucco  [author] 11 Apr, 2020 @ 5:34pm 
@Cacat That was the original intent, but Matz gave me the idea of just making the guy appear in libraries like Greed, which makes him more niche and rare to find rather than a basically guaranteed boss per run.
Cacat 11 Apr, 2020 @ 12:58pm 
Saw the video of the boss, looks very cool. Ever thought of making a version where he's the boss of Chapter 1 or 2?
Перчатки 10 Feb, 2020 @ 6:46am 
nice update! I love it!
EmeraldMoth 7 Feb, 2020 @ 7:49am 
10/10 best update
