Hi guys, I’m new to this fascinating game and in the middle of learning all the rules in the Keeper’s book. I’m have some issues understanding the underlaying.

There are some points I find contradictory:

1. Temporary bout of madness lasts for 1d10 rounds/hours. The rules say that after the bout investigators start suffering from underlying insanity which means receiving even 1 SAN damage causes another bout of madness since under the influence of underlying insanity investigators are being psychologically vulnerable. And it is also said that for the temporary insanity they are vulnerable for 1d10 rounds/hours. At the same time rules dictate that while being insane investigators can’t take any SAN damage. So I can’t figure out how a temporary insanity may become an underlying one. Any help?

2. when indefinite bout of madness is over, does it become a permanent underlying insanity? So that any time after that when an investigator loses even 1 SAN it causes another bout of madness? And btw how does underlying insanity cause another bout of madness? Is it just like investigator automatically losses INT check when got 5+ SAN damage but without actually getting one?

3. there are phobias and manias. To me it seems like you can obtain those as a result of indefinite insanity. Am I right? Cause phobias and manias have a constant effect on investigators having one. And I guess these can’t be a result of temporary insanity since when it’s time is over it doesn’t affect investigators. Can someone comment on that matter too?

Thanks everyone in advance!

I got some more people together to record some Call of Cthulhu with Resident Evil stuff again. We split it into three parts due to more players for breaks and things like that. I know I screwed up some of the rules, especially combat and luck, but thems the breaks sometimes. I'm always open to constructive criticism, however.

Next time I run a game of it, I'm gonna do it long form and have everyone make their own characters because even with the online resources, it's exhausting making all those characters. Thank you for listening.

I will be running my first long-run campaign in May 2025 and I am stuck at coming up with thematic puzzles and mechanics for the last few remaining areas. I am looking for any suggestions regarding what I should use or material that may help me. I have run two One-Shots to prepare me for this and the players I run with are more use to combat from typical DnD rather than mechanics and puzzles in CoC (It doesn't matter to me if your suggestions are harder for them to realize and figure out lol).

Context on Campaign: Early 2000s (flip-phones were still the majority era) and the party is a group of PIs from New York that are wrapped up in a nation-wide conspiracy where they essentially dismantle this shadow organization. I have each enemy org leader sectioned into different sections of ways to control the everyday person: Public Speakers (TED Talks), Military, Entertainers/Singers, Stocks, Food Supplies, etc. I also based the majority of puzzles off of shows that I watched during 2024 because the group I run with doesn't watch a lot of TV (More Anime and Youtube than anything) and that has helped me.

For example: I have a therapist boss whose entire mechanic is centered around the show Severance or the Food Supply area is based off of Hannibal.

The sections that I am struggling with is a Singer with a Cult-like following from the South (was thinking Taylor Swift/Swifties), Public Speakers from the Pacific Northwest and a Military setting based in Texas (I was thinking of CIA brainwashing like from the Black Ops games, but still not sure since I'm using Severance as a mechanic).

If anyone could help, that would be great and I can provide any context if needed.

I'm trying to find a map for my game but my google fu is not good, I'm trying to find a clean usable map of a modern commercial fishing vessel. There are plenty of deckmaps but they're often low quality or more about the size of the boats hull rather than the interior. If you can't find maps i'll just try and draw one.

this is a vent post. I just need to calm the hell down.

EDIT: I would like to add I'm not letting them make the NPC's commit suicide, but they keep trying and won't stop.

Hi guys,

there are tons of playlists for 1920s CoC scenarios but I have a hard time finding ideas for other settings like Dark Ages and Invictus. For the scary parts, you could get away with using similar music, but for the beginning of adventures and calmer parts, do you have any recommendations to reflect the feeling of walking the streets of ancient Rome or a medieval village?

Thanks!

Which books, either Chaosium published or 3rd party, would you say are the best? Not long campaigns like Horror on the Orient Express, but compilations like Nameless Horrors or Fear's Sharp Needles?

Hey Squidward's Call group hahaha but I'm really playing Call of Cthulhu, I started to think, would there be a way to get the Midas curse? Some kind of spell would be interesting. Also Midas vs Squidward (if one doesn't go crazy at first)

My 5pn cst game fell through at 4:59. Anyone wanna play through a one shot called “Darkness Beneath the Hill”?

I was looking up darker ttrpgs and CoC seems like the one that is most popular in that sort of category. The other one was Kult, but I feel that it would be harder finding people down with that lol. I’m about to order the beginner book on CoC, and was wondering if anyone had any tips for it. I’ve barely played any tabletop games like this, so anything no matter how simple is appreciated!

Hey!

I just published an Advent Cthulendar with 24 warm and cozy places and people for investigators backstories. I felt that Call of Cthulhu could use a supplement that warms and brightens investigators' daily life, if only to ramp up the contrast with moments of terror. The Cthulendar is available here, has 29 pages, costs $4.99, and is also available for $3.49 here, in a bundle with the previous Advent Cthulendar from 2022 (this one with 24 definitely not cozy ideas for Keepers).

Covers of both Cthulendars

Hey all, partial newcomer here and I have a heap of questions...

Going to do my best not to write a typical ‘where do i get started?’ post, but here we are. 

A month or so ago, my gf and I were looking at new RPGs we could possibly play co-op (using Mythic) and she brought up CoC. I knew of the game since like 2002 when I was pretty into DnD 3e, but the whole franchise didn’t speak to me. 

Cut to the other day, I’ve downloaded the (admittedly janky) PS4 game and have put a few hours in it and have been blown away—even by that iteration. The world it takes place in is amazing and I got super excited as a born-n-bread Masshole that it seems like much of the plot of this series takes place near my home.

Since then I’ve been on a bit of a Cthulhu wormhole trying to figure out how my gf and I would be able to play this together. So far I’ve gathered that the “Investigators Handbook” is a good place to start with some extra rules geared towards solo, but I want some more info. 

TLDR; I want to get into Cthulhu and play co-op with my gf and maybe add some other friends one day. What books do I need to read (not necessarily just rulebooks for the ttrpg) besides the Investigators Handbook? I would love recommendations for the best ruleset for us, as well as recommendations for which novels I should read to catch up on the lore.

Thanks!

So my friends and I started a scenario got about halfway though it had to stop and said we’d come back and pick up where we left it. However it’s probably been about 3 months now since then and getting a group of 4 fully grown adults togather in one room for a few hours seems to be proving difficult so. Has this happened to any of you. did you abandon the game and move on or keep it to play it once everyone is ready?

I've been running Cthulhu for about two years now, mostly 1920 or Now, and I've noticed that I have some problems determining the decent, travel time and travel options worldwide, i.e. how long it takes with a boat etc.

Happy Thanksgiving everyone! I looked on the Chaosium website and saw certain items on sale already. But does anyone know if Chaosium will be doing a Black Friday sale?

Hello, I am new to Call of Cthulhu,
I was wondering how easy would it be to run 7e in nearly any time of history, for example Ancient Greece, Medieval, etc.

Is it simply just converting some of the skills, like cancelling out the use of guns, and auto driving, then it would be fine? Or is there more that I should consider / look at.

Thank you for any help on this! I have been loving looking into the RPG!

I've noticed within the last few years a number of folks have posted about running this older module, and I would like to try to run it myself for my group. However, I've been unable to find it anywhere except someone selling a used copy for like $70 on Amazon. I'm gonna pass on that. Has this become merely a collectible? I thought I had read that it was out of print, but I didn't realize it was that hard to source! Where have all of you that have run it in the last few years located a copy? Have you found .pdf scans somewhere on the internet, or am I missing something obvious (or both!)?

In case any keeper needs to know how much a human skeleton cost in 1924. You know, for that truly unbalanced investigator.

i'm trying to find an old scenario from probably thirty years ago that featured an "institute for dream research".

i think it was called the windthorp/windthrop institute of dream research. i believe it was in a collection, similar in style and time to the "great old ones" but my know roll has failed.

anyone else remember this and know where it lives?

cheers in advance.

Delta Green is a TTRPG that takes the foundation of the Lovecraft mythos and Call of Cthulhu RPG and expands I to a secret government conspiracy to stomp out the unnatural before the general public discovers it's existence.

The Agents find out that theirs is not the only organization to perceive the danger of the Unnatural.

Hi. I am new to C.o.C., but I am an experienced hand at refereeing a wide variety of R.P.G.s and tabletop games of various sorts. I bought the Starter Set and Doors to Darkness via Humble Bundle recently. Unfortunately, I could not afford the full bundle with the Keeper's Handbook and Investigator Guide, etc. Reading through the starter, we may want to continue playing through further scenarios, but further investment in the fairly pricey rulebooks is unlikely to be affordable for us, and I also hate reading lengthy rulebooks.

Are the basic rules enough? I have little issue with making ad-hoc decisions during gameplay, grabbing rules from whichever sytem I need, etc., and my players prefer my rulings to reading rulebooks themselves, so could I readily continue past Doors of Darkness without investment in the full rules set? Can anyone see any sticking points here?

I only have the Starter Box Set… can I run the adventures in the Keeper Screen if I pick it up… or do I need the full rulebook for those two adventures?

Thanks!
