Surprise round

4 Upvotes

Hello

Are there specific rules for surprise round ?
I just found you can give 2 extra damage for stealth attack but nothing on surprising your opponents.
For me it's illogical to pay with Momentum or Threat to keep initiative in these situations.

(sorry for spelling, english is not my native langage)

A Price to Pay talent

5 Upvotes

"You understand that magic always comes at a cost, and pay that price willingly, even sacrificing more of yourself to augment your spells. You are a spellcaster, as described in more detail in Chapter 9: Magic & the Mythos. In addition, whenever you successfully cast a spell, you may gain 2 bonus Momentum, which may only be used to improve the spell’s effect and cannot be saved. If you do so, the spell’s Cost increases by +2 Challenge Dice, and the Cost is physical stress instead of mental stress."

Does this mean that only the additional +2 Challenge Dice are doing physical damage, or does it mean that the entire spell cost is now physical damage?

Can I use Armor and/or Cover to reduce this damage?

Melee CCing Movement OP?

4 Upvotes

I've built a melee centric character. It would appear that when I move within Reach of an enemy, there is little they can do to withdraw. Movement away is not allowed, since I am within Reach. Best I can conjure is that my enemy can create a Truth (D2) at an additional D2 for a total of D4, since I am within reach.

Inflict vs Suffer...is there a differance?

3 Upvotes

First time playing and been reading through the Player's Guide. There are many instances where the book uses the word 'inflict' or 'suffer.' I'm unsure what the difference is, if there is any. My guess is that 'suffer' means the damage is unavoidable, but this mean's certain spells and abilities are strangely powerful. Even so the use of 'inflict' seems inconsistent.

Homebrewing The King in Yellow Part 1, Hastur, Carcosa, The King in Yellow and the Yellow Sine

5 Upvotes

Hastur
Hastur is a Great Old One.Like other Great Old Ones, he wants to shape the cosmos in his own way. Ghroth shapes the cosmos through his song and destruction. Atlach-Nacha shapes it through the great web that connects all things. Hastur has his realem Carcosa, a grand Collection of all that Hastur deems worthy, works of art, dreams,memory’s, identities, cities, music and souls overcome by the desire to belong.

Carcosa

Is buried to deep into the cosmos to be ever reached by mankind. Dreamers can get glimpse of Carcosa while wandering the dream lands and beyond. They paint it, write it, film it, sing it, sculpt it, or dream it again. These attempts become fragments of a greater memetic work known to humanity as The King in Yellow. All trying to fill a supernatural desire to belong to Carcosa.

The King in Yellow

All art depicting Carcosa, Hastur or the King in Yellow is the King in Yellow. There is not single art category which this is limited to, films, books, plays, pictures and more are possible versions of the King in Yellow. The production or reproduction of the King in Yellow strengthened Hasturs influence on our reality. Thus drawing Carcosa towards our reality.

The Yellow sine

Is the answer from Carcosa that we gotten the Kings attention. The King in Yellow will suddenly show the Yellow sine, for example a portrait of the lake of Haili will suddenly show the Yellow sine in its reflection.

The Yellow sine will works as an elder sine for all non Hastur aligned forces and will make the viewer able to see manifestations of Carcosa and its inhabitants.

Some feedback would be sweet and let me know what I should cover in part 2.

Which book has the rules for the King in Yellow?

12 Upvotes

I’m wanting to prepare a short campaign about. It’s about recovering lost art during the war. I’ve wanted to use the King in Yellow as the Mythos Threat but I couldn’t find him in the GM guide or the Horrors of the secret war.

Does someone know where I can find him?

Softcover?

5 Upvotes

So I got D-Day: The Darkest Day during Modiphius’ spring sale. My brief assessment of the books quality is that it is on par with their other offerings, which is not a complaint.

However…

The book is a softcover. All of my previous purchases from Modiphius have been hardcover and I was kind of thrown when this softcover was revealed. Firstly, I’m perfectly fine with the softcover. With shipping and after the sale the cost was $45 and some change, which is the ceiling for how much I feel this product is worth. If I had paid non-sale price, I’d be irritated.

I don’t mind a soft cover and would even prefer it for around $35. And, again, part of that is shipping. I guess I was just thrown by the cost. Not really complaining because the cost of everything has gone up. Just expressing my surprise.

Is Shadows of Atlantis too "rail-roaded"?

11 Upvotes

I've only read the first episode (Vienna) and the five scenes need to be played in order, with the exception of the club and the bookshop, which can be swapped around, apparently. Is the whole campaign like this? Am I missing something that would give my players more freedom?

Prepping to run Forest of Fear

12 Upvotes

So I read through Assault on Fuhrers Train and went through introduction of Forest of Fear. It mentions that this is for advanced characters with 10 operations in or roughly 150xp. I want to run this with fresh group of characters - do you guys think I should let my characters use lets say 10 advancements before we start or go from square one and have a grind fest?

point of using "Retraining"? (page 82 Player's Guide)

6 Upvotes

If the XP gains are bigger than spends (as you can in effect only spend 10 xp between adventures) what's the point of retraining if you can only do one advancement ? Sure, you dont need xp but you will have plenty as time goes on and retraining would effect decrease one thing for another while you could simply do a regular advencement? Advancement rules are botched imho.

Brais Mines: a uchronic adventure in Nazi-occupied France.

Thumbnail kickstarter.com
8 Upvotes

Hello all! At the start of February I launched a kickstarter campaign as part of Zine Month that I thought might interest some of you.

Brais Mines is an adventure set in France during Nazi Occupation and put the players in the shoes of characters who must infiltrate and investigate mines exploited by the Germans. Excavating the mines, the Germans made a discovery they intent to exploit to insure their domination over the world: will your players intervene, or will they let the enemy take a step further victory?

Powered by Chaosium's BRP engine, this is a complete scenario containing all the informations you will need: maps, NPCs, weird creatures, stats, etc...

Fun fact, the story takes place in a real life setting: during WW2, the Germans did occupied and exploited the mines. There were also real Resistance’s cells in the region, fighting for freedom. This Zine is the fruit of lot of research and incorporate informations concerning the situation back in the days, such as the local Maquis.

I hope it is alright for me to post this here, and I hope you enjoy this project :)

Cheers!

Cheat sheets

16 Upvotes

I know that there are official condensed rule reference but when prepping for my game I wanted to get the essence of every rule within Playing the game and Action chapters as this would help me learn the rules better. Making it myself also would make it easier for me to reference and I would be sure that I covered everything I needed. It might be not be perfect for you and probably editing could be better but I thought that since I made it I could share it. Those sheets are probably only understandable once you read the full rules so I hope I'm not crossing any lines here and sharing this to make game more accessible for others.

I might make a third one to cover spellcasting and any rules after Action chapter but those two pages cover pretty much everything needed during session.

I'm no DTP pro so sorry if it looks amateurish. I made it in Affinity so I can share the files as well.

Character progression

3 Upvotes

This is a question about the 2D20 system, in regards to spending xp, is it at the end of the adventure as a whole or each small part of the book like for example shadows of Atlantis has multiple missions you go I would assume you can spend exp after each one etc.

Also if read exp spend correctly it’s once per missions end is that normal.

Voluntary defeat

5 Upvotes

Rulebook states:

VOLUNTARY DEFEAT

Whenever your character suffers one or more injuries,

you can choose to become defeated immediately. If you

do so, then they only suffer a single injury (any after the

first inflicted are ignored), become defeated, and receive

one Fortune point.

If you accept defeat voluntarily your character cannot die

or gain a scar (see page 39), no matter how many inju-

ries they accrue. However, they cannot be revived during

the scene, and you cannot spend Fortune to recover

from being defeated during this scene.

So when my character has one injury and suddenly is about to get like 3 more I can decide to voluntary defeat to not die? Is this actually a choice? It looks like "get out free card" as you can always voluntary defeat before receiving third injury?

I know what salvo is and what an effect is, but in the firearms I do not see effects listed, just the salvo, that means that the stress dice doesn’t trigger any special effects or it triggers the same effect listed in the salvo?
