DH2E, my players have discovered the joys of Accurate weapons, and now roll around with 4/5th of them carrying sniper rifles, except for the melee guy. It's pretty amazing how many mods they can stack in their favor for shooting.

And how long have they been playing/reading the 40k rpg books?

The Long-Las.
It's elegant, it's grace, it'll burn off your face.

volkite is my weaponfu

As a Tech Priest? Bare hands. I was a nightmare with all Luminen shit I was slangin' at low levels. I liked to think of my guy as fighting a bit like a cyborg version of Heihachi from Tekken.

My Condemnor bolter is my best friend.

...

>What is the weapon you find you can't live without?
Bayonets. Preferably mono or chain, but having an emergency melee "Oh shit" button when using a longarm adds immensely to my peace of mind, even if logically I know it's a glorified security blanket. And then I ask the techpriest about getting a power bayonet or one with Razor Sharp, and I feel even safer.

I wish they'd make any sort of rules for chain or power bayonets beside "yeah they exist"

Chain Attachment in OW, functions as Chain Knife in close combat.

In theory, you can do the same thing with a power knife.

Then stop being tardy about acknowledging the context of the conversation.

What

Where is that

only war hammer of the emprah p121

Shiiiiiiet

What're the stats on this thing

It's a bad photoshop, man. That said? You can get silly amounts of ram damage from an over-armored ship if you give it a Reinforced Prow, an Armored Prow, and a Power Ram.

Why is it the only place you find Power Knives is in BC? It seems like it'd be a ubiquitous weapon in the Imperium.

Because power knives are the signature weapons of the Alpha Legion primarily, and Custodian Guard secondarily. They're rather hard to find.

That's stupid and doesn't make any sense.

it's also the only thing I could hit anything with.

Welcome to 40k, where everything is stupid and makes no sense. This place runs on grimdark and rule of cool. l suggest making your peace with this now.

I love the shotgun and shield combo, especially if the shotgun has a bayonet on it or if it's the "counts as shock maul in melee" shotgun from RT.

>What is the weapon you find you can't live without?
Best Quality Power Maul. Relatively concealable, unobtrusive, useful in lethal and non-lethal takedowns, and can be used to batter down doors in a pinch.

Plasma Revolver

Any corrosive weaponry, especially iron eater grenades. They're remarkably solid support weapons since they chew up the target's armor.

So I'm making an OW regiment. Is it normal that your average trooper will have a fuckton of grenadeS?

Rule of cool's the only rule worth following, really.

Depends on the regiment. Are you making a close-assault one?

I made a regiment where every soldier's given 3 frag grenades, 2 stun grenades, 2 flash grenades, 2 pipe bombs, and 2 demo charges. Do you mean that kind of "a lot"?

If that's how your regiment rolls, that's how they roll.

Having GMed and played Only War games, I do have a bit of advice there, though: Generally speaking, grenades are some of a trooper's best friend. No matter how your regiment's starting kit goes, the individual will eventually get his hands on as much explodium as he can manage. So if they start with a lot because their regimental style involves it, you're basically saving yourself a lot of logi tests.

Grenades are awesome.

Not just for the players, but also for you. Having more consumable heavy ordnance gives your players a panic button and lets you as a GM throw bigger stuff at them (Within Reason).

Your average guardsman squad would never stand a chance against a chaos space marine. But grenades are the great equalizer. While they may not be able to kill the bastard easily, it becomes possible with some well placed krak nades, blind grenades for concealment and stun grenades when you have to run away screaming.

>Your average guardsman squad would never stand a chance against a chaos space marine
Depends on whether your guardsman squad has meltas or krak missiles on them.

Also what kind of Space Marine they are. If they're Khornate, you may be able to lure them into a spot where you can let the environment do the killing or just mass what ordnance you have.

Okay, so let's say that the PC Rogue Trader has gotten engaged to an NPC Rogue Trader (like, say, Madame Charlabelle from Lure of the Expanse), and they're intending to merge their dynasties together, de facto if not de jure.

How would you handle this? Just make the wedding an Endeavor?

I'd certainly run it as an endeavour.

As with any massive political and economic merger, there are going to be people coming out of the woodwork to object, try and get in on the action giggity, and all around make life hard for the pair.

You'll at least have to try and placate the members of each household that they're not going to lose their shit to a whole bunch of new relatives.

As well as trying to deal with all the other Rogue Tradres who will see you as a gigantic fucking threat to their business prospects.

An excellent choice, by the way. That poor woman needs all the help she can get.

Got a couple guys who know the ins and outs, a couple guys who've played some of the vidya and a grill new to it who can't stop psykering.

Well, it has to involve a cunning plan...
Charlabelle's assets are useful by all means, but almost any marriage is to her advantage and to your PCs detriment. Her dynasty is weak and her fleet is feeble. Never marry /down/, unless it's for love, and even then don't get married formally. There is simply too much at stake.

In the thread above, in our game, we had assassinations, politics, Mah-Jong, feuds, counterfeuds, and Orkestra (sadly, purged from the archives), and a few minor wars before we ended up marrying off Lord Captain Olivares to Lady Captain Chorda.

Bah! What is this, a charity auction?

40k is a feudal setting. You marry to secure an alliance, to turn a foe into an ally, to grow your wealth, or to make a subtle move in a long-term game. You don't marry out of /pity/.

If you feel like Madame Charlabelle is deserving of an alliance - and that's fine, she seems sensible enough - make her a vassal in all but name of your dynasty. Sign a trading charter that allows her to move between your colonies and profit by them. Allow her to rebuild her fleet - to your benefit and profit. Perhaps marry her to one of your heirs or cousins - not a /direct/ heir, but enough that you will be tied by blood and parchment.

Madame Charlabelle wants security and a chance to rebuild her dynasty. Give her the time to do it, and her descendants might manage to make something of themselves. Until then, she has a tramp freighter and a forgotten name.

>That lady
I recognize that artstyle, this is the guy that drew grown up Clarissa ss-ing her son isnt it?

I don't... think so?

It's not impossible.davidap.deviantart.com/gallery/

> Never marry /down/, unless it's for love, and even then don't get married formally.
Marrying down can have its benefits, too, as long as you don't marry *too far* down (if there's a commoner you like, you can just add them to your harem of concubines). By marrying down, you get an ally whose metaphorical rising star is firmly tied to your own; the risks of betrayal or corrupt behavior is much lower, since if they bring you down, they bring themselves down, as well.

>In the thread above, in our game, we had assassinations, politics, Mah-Jong, feuds, counterfeuds, and Orkestra (sadly, purged from the archives), and a few minor wars before we ended up marrying off Lord Captain Olivares to Lady Captain Chorda.
I wouldn't, personally; Aspyce Chorda seems like more than a bit of a bitch (and even if personality isn't the most important thing, you're still going to have to spend a decent chunk of the rest of your life around them), and, more importantly, she's very heavily involved in corruption (of the financial variety, not the Chaos variety).

>Madame Charlabelle wants security and a chance to rebuild her dynasty. Give her the time to do it, and her descendants might manage to make something of themselves. Until then, she has a tramp freighter and a forgotten name.
She's the only NPC Rogue Trader who comes out of the Dread Pearl with any noteworthy profit, and don't underestimate how useful a tramp freighter can be; most ships can only carry tiny amounts of cargo in comparison, and if you've managed to leverage the Zayth adventure into a peace summit, well, you've got a Hive World's vast manufacturing abilities combined with its endless hunger for food and raw materials, and she's got just the ship to take advantage of that.

Also, if the PC party decided to go for Ship Points rather than Profit Factor during CharGen, she's not much more worse off than they are.

So, out of curiosity, has anyone here ever completed the Warpstorm Trilogy, and if so, how did your fight with Karrad Vall go? Looking at his stat blocks, he seems pretty strong...

we did, though our campaign was a mix of Lure of the Expanse and the Warpstorm Trilogy.
We faced karrad Valls over Iniquity : while half the team was heisting his vaults, looking for one of the map to the Dread pearl, the RT basically asked to meet him, wanting to join, tempted by the offers from slaaneshi agents she has received before. She went on his bridge, alone except for her fanfare, and challenged him to a tango.
And stabbed him with a power stake. Considering that she is an augmenticist strong enough to lift a chimera, it hurt a lot. she then teleported back to her ship, running away at all speed for an emergency jump, most of the loot of his vault inside her own cargo bays.
it would have prooved not enough, with Valss recovering and about to pursue, if the seneschal during the heist had not recognised, inside Vall's vault, that there was there Exterminatus Warhead, an archeotech mass-to-energy converter.
It wasn't fired toward the OPTIMUS NEMESIS. nor blown on Inequity itself. he fired it toward the black hole at the middle of the system...

they broke the segmentum record of the larget man-made explosion with that.

and tfor those who were asking : what de we fight inise Lu'nassad when it came near Footfall ? well, it appeared that when lu'nassad was corrupted, they tried to summon the Avatar to help them. In vain.
So when we entered the center of the corrupted Craftworld, we were charged by a godamned corrupted Avatar of Khaine. A hell of a fight.

though, we are about to close the campaign soon, going too to the last climatic fight : destroying Erasmus motherfucking Haarlock over the Dread Pearl.

>the risks of betrayal or corrupt behavior is much lower, since if they bring you down, they bring themselves down, as well.

I'm not sure I agree - if it seems like the only way to step out of your shadow is by knocking you over, they will.

The plural of "Rogue Trader" is "war". Always has been.

>Aspyce Chorda seems like more than a bit of a bitch

You are not wrong. She's more than unreasonably crazy.

But her sister Anastasia, whom we found frozen in a cryotube, decanted, and use to steal a fair portion of the Chorda dynasty's fleet via a rigged game of Mah-Jong, a carpet cleaning machine, and some allies willing to wager a cruiser each

>you're still going to have to spend a decent chunk of the rest of your life around them

Oh hardly. You have a starship. They have a starship. You're not retiring to a cabin on Solace to read devotional tracts. There's plenty of Rogue Trading to be done - if you want little heirs, get the Tech-Priests to help. No need for one of you to carry the child personally.

>he's very heavily involved in corruption (of the financial variety, not the Chaos variety).

Again: Rogue. Trader.

If you aren't involved in financial corruption, there are two options. Either you are, and your Seneschal hasn't told you, or you aren't, and you're going to be robbed blind by people who are.

>and she's got just the ship to take advantage of that.

Correct! But that's one trade route from one world - worthy of a Chartist captain or an impoverished Rogue Trader house, but not worth an offer of marriage. Other alliances could be formed.

>Also, if the PC party decided to go for Ship Points rather than Profit Factor during CharGen, she's not much more worse off than they are.

Save for the fact that /they/ are the PCs, and she is not.

>I'm not sure I agree - if it seems like the only way to step out of your shadow is by knocking you over, they will.
So you need to arrange the incentives so that it's a bad idea for them to do so: the risks outweighing the rewards.

>Oh hardly. You have a starship. They have a starship. You're not retiring to a cabin on Solace to read devotional tracts. There's plenty of Rogue Trading to be done - if you want little heirs, get the Tech-Priests to help. No need for one of you to carry the child personally.
You're still going to living for hundreds of years if nothing goes wrong, and even if your primary method of communication is through astropathic messages, you're still going to be talking to them a lot; if they fuck up badly enough, you're going to be helping clean up, or getting caught in the crossfire.

Also, personal interactions build loyalty and cost little. This especially applies to sexual interactions, due to the hormones and neurotransmitters released during orgasm.

>If you aren't involved in financial corruption, there are two options. Either you are, and your Seneschal hasn't told you, or you aren't, and you're going to be robbed blind by people who are.
Well, when your Seneschal is a member of the Adepta Sororitas' Order Famulus...

Besides, money that's being spent bribing officials is money that's not being divided among your key supporters to buy loyalty.

>Correct! But that's one trade route from one world - worthy of a Chartist captain or an impoverished Rogue Trader house, but not worth an offer of marriage. Other alliances could be formed.

More than one route. Mining colonies to Zayth, Agri-worlds to Zayth, Zayth to the closest Munitorum depot, Naval base, or local warzone...

Selling Macrocannons to the Navy is likely to be pretty profitable.

>Save for the fact that /they/ are the PCs, and she is not.
Well, that's a bit of an out-of-character justification, now isn't it?

Hell yeah

If they're smart they'll open every encounter with grenades

Is it possible for a weapon to be "stained" with good deeds instead of daemonic influence? For it to be passed on from hero to hero, doing great deeds and being slowly coated in the blood of the imperium's enemies?

And if so, how would you represent it in crunch terms? Besides just saying sanctified and calling it at that

That's literally what Sanctified weapons are.

Particularly holy ones (e.g. the personal relics of Saints) might get the Daemonbane trait or special rules of their own.

That's pretty much what Relic or Sanctified weapons are/do

Any of you guys ever played a possessed marine? If and when I find a black crusade group I intend to make that a character
goal. And I was wondering if looseing out on ascension is worth it? Because exploding into a daemon and having your soul mercifully absorbed by said daemon doesn't sound to bad. Considering the alternative is spawndom.

If I could be a gal vorbak, totally. But that isn't an option.

I'd do it just for the fun of it

>So you need to arrange the incentives so that it's a bad idea for them to do so: the risks outweighing the rewards.

Right, so you can design a contract that enforces these terms, but if they're too unfavourable, they won't sign. Even if there are no loopholes, there's always plausible deniability. Those aren't /my/ ships, those are just temporary space stations or very large cafes.

And no Rogue Trader will consent to be a lesser partner in a long-term enterprise if they can help it. Would you?

>You're still going to living for hundreds of years if nothing goes wrong
If you're lucky. Very, very lucky.

>'re still going to be talking to them a lot; if they fuck up badly enough, you're going to be helping clean up, or getting caught in the crossfire.

Absolutely! There's just no reason to be in love with this person - if you help out, it's for sensible reasons. No suicidal charges required.

>Well, when your Seneschal is a member of the Adepta Sororitas' Order Famulus...

Sorry, in that case, "tithed blind".

Or manipulated. What does the Order think of marrying these 2 dynasties? Do they have plans of their own for the Rogue Trader's lineage(s)?

>More than one route. Mining colonies to Zayth, Agri-worlds to Zayth, Zayth to the closest Munitorum depot, Naval base, or local warzone...

In a rustbucket tub? You'd need at least 2 escorts to make long-distance runs safely. The Expanse is very dangerous.

>Well, that's a bit of an out-of-character justification, now isn't it?

Rogue Trader is probably the only game where the characters can make an assumption /similar/ to that, and not only be right, but also have it be totally fit the setting and tone. It's a game of egos, bravado, and ludicrous plans.

If you have a high enough will score you can easily change back to a human like form. It's a rule where you can turn any appendage into it's original form.

>Reaper autocannon
>Storm

Gal Vorbak died in the middle of the Heresy. After Argel Tal died, there was only 1 left, iirc. All others after them were Vakrah Jal, which were slightly better than modern possesed, but far inferior to Gal Vorbak. The SoH had their own version, but were literally just modern day possesed.

How specific do I have to be when it comes to the hatred talent?

Chaos space marines don't seem to be divided into chapters or patron Gods so I guess I just need one for cultists and one for CSM, But is it possible to lump in the cultists with just plain severans and go Hatred: Traitors?

And there will never be new Gal Vorbak because ADB declared a specific set of circumstances that meant nobody could EVER reach that level.

Grenades. Specially bag of grenades.

That's perfectly valid

I would assume that as a guardsman or some other member of the Imperium that it would be safe to assume that anyone interfering with your inquiries/lawful duties is considered a traitor right? From the hive gangers that try to mug you to the nobles that intentionally withdrew information to protect their interests.

Or would heretic be a better term to ensure harmony with your GM?

quick question - which of the books of any and all of the RPGs have gear in them besides the core ones? I'm compiling a huge pile of gear from wh40k

All of the splats?

any of them have stuff substantially different in form or funtion from what's in the core?

Yes. Did you ever look in one?

Yes, however watch out as some of it is objectively better, and under-costed.

It's like, my biggest grip with FFG.
They do it in EVERYTHING.

Just ban everything not core so the game is balanced.

It is D&D 3.5 all over again.

Oh, I thought you meant Traitor as in Traitor Marine. The examples for Hatred include Mutants, Heretics, specific institutions and the like, so Traitors et all would be a way too broad scope, I feel.

no, not yet, frankly. Seems like I will have to

That's a step too far mate.
You've just got to watch out for some of that stuff.
Adjust rarities, change opposition so it's actually a fun challenge and so forth.

Except in 3.5, banning core markedly improved the game.
That's way too far, just have some common sense and be able to tell when something is too good, and hit it with the nerf-bat appropriately.

So, I just started running a Rogue Trader game for a bunch of relatively new guys to 40k, just ran them through the campaign from the end of the core and a pair of systems that I fluffed up from some basic ideas. The problem I'm running into is that I can't think of a campaign idea to go with the freedom that they've come to expect from what I've given them so far.

Also, as they've learned more about the setting, they've asked me to do a space marine campaign after Rogue Trader, but I've been wondering, is it possible to run Deathwatch during the Great Crusade? It'd probably be something my players would really enjoy if I could set it up right.

>a campaign idea to go with the freedom that they've come to expect from what I've given them so far.

"A warp storm opened up a sector long thought lost. Go wring out all its shekels."
"There is a legendary treasure somewhere in the sector, but the map is split between numerous places, KOTOR style. Find the fukken map."

>is it possible to run Deathwatch during the Great Crusade?

It is. The core Deathwatch can be modified easily, and there's a "Great Crusade Testing Ground" file made by Shas that stats out all the vehicles, weapons, rites of war, even some new classes like the Breacher, Seeker, and Consul.

Like most things in crunch, diversely-written tabletop games, it's mostly about the flavour.

Sure, you can spend hours poring over every book to find the right combination of scope, ammo, gun, and addons to become the /best/ at killing.

But what's the goddamn point?

Just go pick gear that seems cool and you'll do just fine. Choose what fits the character, what's local, what's evocative, and what seems neat.

Would your character /really/ give up their ancestral power sword for a newly manufactured blade that has +1 damage?

Would they give up their angled blast-plate from their long-lost hiveworld home for a badly fitted set of carapace armour, just for a slight bonus?

It's totally feasible for a Rogue Trader to spend all 8 ranks with the same bolt pistol and power sword.

>Like most things in crunch, diversely-written tabletop games, it's mostly about the flavour
That's a perspective that you and I share, but sadly my players do not.

And please don't say "find better players".
Because I've looked.
And these are the best I can fucking find.
God help me.

Have you tried sacrificing them to the dark gods?

Do you have other friends or acquaintances you could turn into players?

Experience is not required. Being a decent human being is.

Thanks for the advice user, but where can I find that file? I don't see it in the mega and google gave me some ebooks.

[Set to organ music]

The crash of cannon from on high
Heralds the Lord Captain’s arrival.
He causes enemies to fly
And proclaims everyone’s survival.

Lord Captain! My Captain!
Invincible and brave!
Lord Captain! My Captain!
Another quite close shave!

Anything he wants he gets
And what’s left over’s not worth getting.
He is a master with a blade,
Mah-jong and other forms of betting.

Lord Captain! My Captain!
A leader without peer!
Lord Captain! My Captain!
See how his rivals fear!

Lord Captain! My Captain!
He fights for you and me!
Lord Captain! My Captain!
He’s assured victory!

Great job on giving nothing to go on besides 'alternate reality'.

The Punished Wasp demands stories. Particularly of psykers or cogboys murderizing everything that isn't them or their allies.

We had Thomas Turlington, noble psyker, fop, and fool.

This was in the FateCore hack I'd built, and psychic poweres worked like this. You made your roll to activate them. If you failed, Perils, as per the 40k RPG table, with +10 for each point of failure.

But if you succeeded, the Warp also attacked you back. It rolled against your Faith, with a bonus equal to half your successes. So if you succeed with +6, the Warp got a +3 to attack you back. If you failed, Corruption damage, and also Perils.

Thomas was notorious for getting helpful Perils. He once Mind-Swapped with an NPC he was attempting to dominate (and basically possess) which ended up with him succeeding, possessing him, and then mind-swapping back to his original body. The NPC couldn't handle the shock. Thomas just whimpered.

Another time, he tried to use his telepathy to get a guard on the inside of a locked blast-door to open it. The Perils roll instead caused all tech-devices in the area to fail... including the door's mag-locks. And another PC's bionic arm and leg. And the local gravity.

Speaking of gravity, he rolled Gravity Reversal while climbing a huge, rickety gantry tower. The entire tower made it 50m into the air before the effects wore off, leading to a huge catastrophic crash that sent all the PCs but one into critical care for months.

OK, so my players are at a weird point in spacetime where dozens of alternate realities converge due to warp fuckery. Some are grimmer and darker, some nobler and brighter, some populated by literal cosmic horror monster people. They're going to fight a motley collection of freaks and cosmic outcasts from multiple dimensions.

There are no wrong answers here, but I'd like some of the more exotic stuff. I've got a black hole gun as a piece of insane archeotech from a reality where humanity is still at it's apex, a metal man from a reality where they wiped humanity, and a rad-flamer from a reality where mankind stuck to atomic weaponry.

>even the gravity
>mfw
How has he not killed himself yet?

Luck and only using his abilities when he needs to. He's a passable socialite and decent at stealth as well.

He also runs away a lot, especially from the vengeful ghost of Matthias Haarlock.

To be fair, /everyone/ runs away from the vengeful ghost of Matthias Haarlock.

One of these:

antlerrr.blogspot.ca/2015/02/blur.html

(suitably refluffed, of course)

>Luck and only using his abilities when he needs to.
Any times when his luck nearly ran out?

>where dozens of alternate realities

40k has that?

No one ever said it can't. If ships in the warp can find themselves at their destination before they left, who's to say they can't arrive in a different version of reality?

Yes, 40k has different realities and dimensions beyond the Materium, Immaterium, and Webway. One explicit example is the Chromes, metallic insect xenos from "between realities," from the Beast series. There are all sorts of kosmic threats one can face if the right doors are opened.
