Imperium Maledictum is a new Warhammer 40,000 roleplaying game set in the glorious Macharian Sector, a sector forged in blood and fire from the thousand worlds conquered by Lord Solar Macharius. It is a sector rife with peril and treachery,

Imperium Maledictum uses a familiar but refined d100 system to draw players into tales of intrigue, betrayal, and conspiracy. Players take on the role of Imperial adepts and citizens recruited by a powerful Patron. These influential figures use teams outside the usual chain of command to undertake grim and perilous missions, furthering their often inscrutable interests. To succeed, players must weave their way through the complicated web of competing factions that make up the Imperium. They must navigate a realm where a whispered accusation can be as deadly as any bolter, plumbing the depths of the most lethal hives and navigating the often far more insidious threats that grace the courts of the highborn.

Do you have what it takes to survive the grim and treacherous adventures in the 41st Millennium?

I think there is a bug in Feral World origin:

Ok ive never played any of the previous wh40k rpgs before but the concept here appeals to me (it has kind of a neovictorian cyberpunk vibe to it.) How difficult is the system to learn from both a player and gm's perspective. I understand that its a d100 based mechanic but thats about it.

The system itself is a mix of a very simple core mechanic along with several subsystems (none of which are terribly complex individually, but taken together add considerable bulk to the rules). However, there is a lot of minutiae in the record-keeping of this game that I feel could push casual players away.

The maths for ranged attacks doesn't seem to work - if i'm understanding it correctly.
Assume the simplest situation: an attacker with BS 30 shoots a target with Reflex 40. The attacker has a 30% chance to hit and do up to +3 damage.
If the target dodges and it becomes an opposed roll, the attacker now has a ~33% chance to hit and do up to +9 damage, due to opposed roles going off difference in SL only. The attacker will still hit with (for example) a roll if 60 if the target rolls 80 or more: -3SL vs -4 SL. And if the attacker rolls 01 for +3SL and the target rolls 90 for -5SL the attack does +9 damage.
Of course there are criticals and fumbles and modifiers and situations that grant advantage and disadvantage and add or subtract SL. But at its core the maths makes dodging a worse option even in some cases where your Reflex is higher than the BS.
I can see one reason why they may have built opposed rolls like this: it means you don't have to decide what happens in opposed tests where both...See more

Actually, I think I did get the maths wrong. The chance of the attacker with BS 30 hitting the target with Reflex 40 is ~36%

Here's the calculation. Basically the target must get at least one SL less than the attacker. So if the attacker gets +3SL the target must get +2SL or worse, if the attacker gets +2SL the target must get +1SL or worse, etc.

BS 30 Reflex 40
01 to 09 20 to 100 729
10 to 19 30 to 100 710
20 to 29 40 to 100 610
30 to 39 50 to 100 510
40 to 49 60 to 100 410
50 to 59 70 to 100 310
60 to 69 80 to 100 210
70 to 79 90 to 100 110
80 to 89 100 10

So 36.09%

This latest update remedies a great number of typographical errors, balance issues, and rules inconsistencies. As a result of the numerous improvements--not least of which is the generous addition of helpful Marginals where there was previously only empty space--the book appears much more polished. I'm genuinely relieved to see how thoroughly the development team has revamped the core book, even fixing issues that I hadn't publicly listed here or elsewhere. After scanning the majority of the PDF, I've so far only come across the following issues:

* Two references to "Endurance (Pain)" when the Skill + Specialisation combo should be "Fortitude (Pain)"
* Three instances of the word "wield" being misspelled as "weild"
* The PROMOTIONS section of the Bestiary using the word "Skill" instead of "Skills" to reference multiple Skills (p. 318)
* The Aim Action inherently removes Disadvantage from the Target a Location Action,...See more

Late Edit: The identified issue with Mesh armour should really be more of a suggestion, rather than an actual issue. It's probably more of a problem with granularity than of any true imbalance / inconsistency. Although the current stats for Mesh armours indicate they aren't meaningfully lighter than many Flak armours, they do provide more protection for the same amount of encumbrance.

When is the next revision of the core book going to be released? I recall that there was a new revision being released every week for a little while. I ask because there are still a wide variety of misspelled words, missing / contradicting references, and straight-up broken rules / mechanics. Just as a few examples:

* There is an instance of "mission" being misspelled as "misssion"
* References to the "Theology (Lore)" Skill should be "Lore (Theology)"
* The "Adrenaline Acceleration" Talent mentions an increase to a Character's Speed in Pursuits or during Fleeing, yet the rules for Pursuits and Fleeing make no mention of how Speed comes into play
* The "Deadeye" Talent's second level, when taking the Aim action, provides Advantage only to attacks Targeting a Location; Rules-As-Written, a standard attack would not receive Advantage
* Master Crafting rules still require tweaking (i.e. Master Crafted Robes cost 500...See more

I've seen your review and referencing a extensive list of suggested edits and revisions. Could you provide a google drive link to those edits so that the community can cross reference it with the pdf provided here in the interim? I think its helpful to have that as a reference to avoid future issues.

I really like this book, but I have one rules question I hope Cubicle 7 can help me with.
Do attacks rolling Criticals inflict a Critical Hit effect even if no Wounds are inflicted due to Armor, Thoughness etc?
Or are Critical Hits ignored if no damage is inflicted?

Example: Can a Ganger with Brass Knuckles even hope to injure an Astartes in a Power Armor?

Malkav A April 14, 2023 10:05 am UTC

PURCHASER

I think I can answer this.

Toughness no longer plays a role in damage reduction; it's solely used for Toughness-based Skill Tests and calculating a Character's Wounds. As for Critical Hits, these are without respect to damage. A Critical Hit means that a Critical Wound (effect) is automatically applied from the Critical Wound Table, as per the rules for a Critical Hit. Critical Wounds that aren't a result of Damage in excess of the target's Wounds are almost never lethal, though they can certainly be debilitating. Pages 213 and 215 explain the Critical Hit process in detail.

So, a lucky Hive City ganger can break a Space Marine's ribs with brass knuckles while he's wearing Terminator Armor. This sounds weird to me...

Shane Y April 15, 2023 8:38 am UTC

PURCHASER

There aren't any Space Marines in Imperium Maledictus so far so that isn't a scenario that's covered by the rules at the moment, but if there were I have a feeling we'd see something akin to the True Grit talent from the older Deathwatch where they reduce/ignore Criticals. Probably accompanied by a certain amount of condition immunity.

Eirik B April 16, 2023 1:37 pm UTC

PURCHASER

Well, the example could be used for Battle Sisters too. They wear Power Armour, but two or three sneaky characters with starter weapons can easily take her down in a round, as that Power Armour doesn't protect against Critical Hits at all.

One way to make the rules for Critical Hits a bit more sensible would be to subtract the armor value from the critical severity, adjusted by Penetration. If this reduces the severity to 0 or below, the crit is ignored.
So that Space Marine or Battle Sister would effectively be immune to a lucky Critical Hit or a sneaky attack from the shadows unless the weapon had Penetration.

Anyway, I'm sure it seems silly to discuss realism in a game set in the 40K universe, but the way the rules stand now, it seems to counter the in-universe power of heavily armored warriors (that are sure to crop up now and again as the game line goes on).

Olaf S April 17, 2023 9:39 am UTC

I would say, that is the beauty of a "death by crit" system. The terminator is probably more akin to a vehicle, the sororita should be in peril if 2 gonks with a knife attack from hiding (knife to the eye, weak spot in the armour etc.). OR shoot from ambush with their las-weapons. The severity of that critical is only 1D10 so no immediate death. That beeing said, if the group needs the comfort of "I can not be hurt": One could rule that a critical of a hit that does no damage after armour reduction only produces 1d10 wounds or somesuch.
But yes, combat is deadly and that ganger with the shoddy laspistol can kill you (or make your life miserable)...

Eirik B April 17, 2023 9:51 am UTC

PURCHASER

I see the point. Warhammer RPGs love their Critical Tables.
But it doesn't mesh well with the universe as described in the fiction and the other 40k game lines, in my opinion. A person in a Power Armour should be practically invulnerable to knives and small arms. How do you even break the ribs of a person encased in inches of hardened ceramite? These suits have no weak points, unless the wearer has their helmets off.

Olaf S April 17, 2023 9:55 pm UTC

PURCHASER

Actual in table top (at least the versions I have played) a power armor is only partially better than carapace (1 in 3 of wounds inflicted saved). So IF you hit and wound, it can be fatal. And narratively it is possible. Neck, Armjoints etc. or you tripped her/him and the impact bruised/broke someting - what ever. And as mentioned above: If you do not like it, change it. These are only rules, a framework. I personally like the sense of danger 4 goblins with shortbows and spears represent (8% chance of criticals thanks to impale) whereas in other systems a 2handed sword is a little back-scratcher. But this is only combat... the most danger is going corrupt or insane (or both) anyway... :-)

Shane Y April 18, 2023 10:30 am UTC

PURCHASER

It meshes pretty well with the fiction I feel. Across the novels and sourcebooks we have plenty of examples of Astartes being slain by pretty basic weaponry. A Word Bearer captain gets stabbed through the under-arm armour seals by a Caveman with a wooden spear and it cuts through something important in the Horus Heresy, knives through weakspots in the armour where the joints and neck are, an explosion sending shrapnel into the gaps between the chest and waist plates, or hits to the power pack shutting down the armour.
With you needing to have both a success and doubles to score a critical, I think it's a pretty good representation of these lucky shots that can inhibit or stagged even the most well armored foes.
With enough righteous fury rolls in Dark Heresy you could kill someone in power armour with a stub automatic, and it's much the same in IM as well.

Malkav A April 21, 2023 12:29 am UTC

The system definitely has some oddities. I've already come up with a small set of minor homebrew modifications to suit my preferences.

I like my combat extremely gritty and realistic, but absolutely love the way C7 has abstracted away much of the tedium from previous systems. The system I'm going to playtest with a couple different groups does away entirely with Wounds (effectively Hit Points). Instead, the Damage in excess of the target's Armour and other reductions--"Wounding Damage"--is compared to the target's Toughness Bonus. Wounding Damage that doesn't exceed the target's TB is a Minor Injury. Wounding Damage that doesn't exceed twice the target's TB is instead a Major Injury. Wounding Damage that exceeds twice the target's TB is a Mortal Injury.

Then, dice are rolled for the Injury Chart (a chart that is essentially the Critical Wounds table, with some slight reworks) for the appropriate Hit Location. The dice determine which general Injury effect is applied....See more

Stub Pistol?

James W April 21, 2023 9:55 pm UTC

PURCHASER

I am almost positive this is a stub pistol. Since there is a Stub Revolver, it was probably called the Stub Automatic at some point, and then changed to just stub pistol, (being the default) and stub revolver.

While it makes sense to have stub automatic and stub revolver, i think most of the fiction simply calls them stub pistols. That is probably why they changed it.

So, the general consensus is to wait a week or two and see if they do an update to fix the issues? How's the general game play? I've seen mixed reviews.

Brayden H April 10, 2023 11:02 pm UTC

Personally I would say it is good overall (7/10 at the time of writing this). It does some things better and others worse compared to the older 40k RPGs. As someone whop has played/ran Rogue Trader, Dark Heresy 1E, Only War, Deathwatch and Black Crusade, I would say Imperium Maledictum is NOT a good replacement for people who want those systems to return. It is a very different beast with a lot more streamlined mechanics and a focus on the Imperium broadly instead of focusing on one aspect of it like the prior systems did. It's a less action-focused d100 version of Wrath & Glory in a lot of ways while still keeping a good chunk of the core gameplay of the old d100 systems with things like Range and Movement being massively streamlined. I personally prefer to run this over the old systems because, while they had a lot of crunch, the older 40k TTRPGs were very clunky (way clunkier than this or WFRP 4E), with mountains of cumbersome rules, and combat would often get bogged down hard with various actions, penalties,...See more

You can not "generate" a bolt gun through that boon... you can humbly petition your Master to gracefully provide you with that marvel of the Omnissia. AND then you don't have Ammunition. AND your Master will probably frown upon you when you return and ask AGAIN: "By the Omnissia, the standard service time for a Lathe-Pattern Boltgun is 231 Standard Years. Where is yours?" "Err... I might have misplaced it?" (sold for 2500 solars to gamble away) "Skitarii! Misplace this wretched bioform to the corpse starch factory!"
Apart from that... Bolter weapons should probably be "rare" anyway.

I do understand your point, and fact that I point it out should suggest that I am of the same mind that it should work differently, however not everybody who will get this book understand the lore or is experienced and this should be addressed. Either it is the way that this boon should work, then mechanically is balanced and homeruling should take it into account (that player should have better equipment) or this is oversite and not intended then for the sake of new players, people who like to play game with mechanics as is and those who don’t know the lore it should be corrected. I do like core of this system however there is lots of things that need some more polishing, so to avoid situation when you must provide every time when you introduce someone new to the system not only book but also extended homerule section which is „explaining” details of the game and what author probably had in mind.
