WARHAMMER 40K DARK HERESY HOUSE RULES
The following is a list of House Rules for use with Dark Heresy. In a few cases, these are just modifications to match Dark Heresy to
the later versions of Warhammer 40k RPG—most notably Rogue Trader.
RULES
Below is a list of updated or changed rule mechanics.
ARMOUR AND FALLING DAMAGE
Armour does provide some protection against Damage from
falling, but is not as effective as normal (except power armour).
For all armour other than power armour, halve the armour’s
Armour Protection value (round up) against this Damage. Types
of armour with the Primitive quality provide no protection at all.
ARMOUR AND STEALTH
Some types of armour impose a penalty on Concealment and
Silent Move Tests, though most do not. Wearing any type of
carapace armour imposes a –10 penalty on such Tests, whilst
wearing any type of power armour imposes a –30 penalty.
AWARENESS MODIFIERS
Circumstance Modifier
Full blown war; battle involving tanks or other
very powerful weapons Trivial (+60)
Pitched battle involving heavy weapons, explo-
sives and/or grenades Simple (+40)
Battle with regular weapons; agonised screams;
heavy traffic Easy (+30)
Combat only involving melee weapons and/or
silenced firearms; yelling and/or an argument;
traffic; adjacent to source (2m or less away)
Routine (+20)
Loud conversation, light traffic, and so on;
close to source (3m to 5m away) Ordinary (+10)
General noise such as conversation, walking,
and so on; near to source (6m to 10m away)
Challenging
(+0)
Quiet conversation or similar; away from source
(11m to 20m); door or light wall in the way
Mildly distracted (close to any distracting activ-
ity but not directly involved)
Difficult (–10)
Whisper or similar; far from source (21m to
50m away); heavy door, regular wall or floor
in the way (wooden or light metal)
Asleep or distracted (undertaking any activity
that requires concentration)
Hard (–20)
Sounds of breathing or similar; very far from
source (51m to 100m away); steel door or
heavy wall or floor in the way (e.g. brick)
Very Hard
(–30)
Distant from source (101m to 250m away); thick
steel door or rockcrete wall or floor in the way Arduous (–40)
Very distant from source (251m to 1000m
away)
Punishing
(–50)
Extremely distant from source (more than 1km
away); blast door or bulkhead in the way Hellish (–60)
CARRYING CAPACITY
When calculating the total of a character’s Strength Bonus and
Toughness Bonus, add the individual Characteristic Scores to-
gether and use the tens digit of this total value.
For example, a character with a Strength of 33 and a Tough-
ness of 38 has a total value of 71, and hence an effective total
bonus of 7 for the purpose of determining his carrying capacity.
CONCEALMENT AND SILENT MOVE MODIFIERS
Circumstance Modifier**
Full cover or concealment (cannot see any
part of the creature’s body at all) Easy (+30)
Immobile (creature is not moving any part of
its body at all) Routine (+20)
Stationary (may be carefully easing out a
weapon or similar); partial cover or con-
cealment (less than half its body is visible)
Ordinary (+10)
Moving at half speed Challenging (+0)
Moving at full speed Difficult (–10)
Open area or noisy surface Hard (–20)
Sniping* Very Hard (–30)
Charging or running Arduous (–40)
*Using the Sniping Action requires a Half Action immediately
after each attack to remain hidden (i.e. the attacker must make a
Standard Attack and then spend a Half Action to stay hidden).
**Apply a creature’s size modifier to both Concealment and
Silent Move Tests.
DEFENSIVE STANCE (HALF OR FULL ACTION)
You strike no blows this Round as you concentrate on self de-
fence. Until the start of your next Turn, opponents suffer a –10
penalty (if you used a Half Action) or a –20 penalty (if you used
a Full Action) to Weapon Skill Tests made to attack you. You
must be wielding a melee weapon in order to use this Action.
GRAPPLING
While grappling with an opponent, you may only take Grapple
Actions, except as noted below. While in control of the grapple,
you may make a Grapple Test (which is an Opposed Strength
Test with your foe) to deal unarmed Damage to your opponent
(1d5–3+SB). As with unarmed combat, a Grapple Test that
causes Damage equal to or greater than your opponent’s Tough-
ness Bonus also causes one level of Fatigue. If the opponent
wins, no Damage is dealt. You may also take purely mental
actions, such as using a psychic power. If your opponent is in
control of the grapple, you must first pass a Willpower Test to
maintain your concentration. While in control of a grapple, you
may disengage from the grapple as a Half Action.
If your opponent is in control of the grapple, you may make a
Grapple Test to take control of the grapple. If you win the Test,
you may either escape the grapple, or you may stay in the grap-
ple in order to injure your opponent next Turn.
Page 2 of 9 Dark Heresy House Rules (v1.21) by Adrian Orlando
Creatures with the Natural Weapons trait use that Damage in
place of the normal unarmed Damage while grappling, but they
do not inflict levels of Fatigue upon their opponent. (They tend
to tear them to shreds instead!)
A character may attempt to draw a small one-handed weapon
(knife or compact Pistol weapon without the Accurate, Storm or
Twin-Linked qualities) with a Challenging (+0) Grapple Test.
Attacking with such a weapon requires a Difficult (–10) Grap-
ple Test; a failure by three or more degrees results in the charac-
ter being forced to drop the weapon. The opponent cannot use a
Reaction to avoid the attack. If your opponent is in control of the
grapple, you suffer a –30 penalty on these Tests.
LEAPING AND JUMPING
In a Running Leap, a character must choose to take either a Full
Move Action or a Run Action. The character must move at least
four metres in a straight line before his leap. He then makes a
Challenging (+0) Strength Test. He clears a distance equal to
his Strength Bonus times 50cm, plus or minus 50cm on a suc-
cess or failure and for every degree, with a minimum equal to
his Strength Bonus times 10cm. For every additional four metres
of run up, the character gains a +10 bonus on his Strength Test
(maximum +30 bonus).
In a Standing Leap, the character does not need to move first,
but must make a Difficult (–10) Strength Test instead.
When Jumping Up, the character must make a Challenging (+0)
Strength Test. If he makes a run up in a straight line of at least
four metres, he gains a +10 bonus on this Test. The character
clears a height of his Strength Bonus times 20cm, plus or minus
10cm on a success or failure, and per degree of success or fail-
ure, with no minimum height.
When Jumping Down, a character must make a Challenging
(+0) Agility Test. On a success, he jumps down a distance of
1m plus 1m per degree of success without taking Falling Dam-
age. Further distance counts as normal falling distance. On a
failure, increase the effective falling distance by 1m for every
two degrees of failure.
OVERWATCH
The Overwatch Action can be used with a weapon in semi-auto
mode, in which case the subsequent Pinning Test is only Chal-
lenging (+0). Use the modifiers given in Opposed Reactions to
determine who acts first, in place of the standard rules given in
the DARK HERESY CORE RULEBOOK.
PINNING
A character who is in cover and who fails his Pinning Test by
two degrees or less may choose the following option in place of
his normal restrictions due to being pinned. The character may
take a Full Action or two Half Actions, as long as the Actions do
not cause any part of his body to leave cover. For example, he
could spend a Full Action to reload his gun whilst remaining
crouched down behind cover.
PSY FOCUS
A psyker who is not in possession of a psy focus is not impaired
in manifesting psychic powers, but runs a higher risk of suffer-
ing adverse effects.
When manifesting a power at Fettered level, the psychic trig-
gers Psychic Phenomena as normal for each result of ‘9’.
When manifesting a power at Unfettered level, the psyker
must roll twice on the Psychic Phenomena table for each in-
stance triggered, and the GM chooses the worst result; if the
psyker uses a Fate Point to reroll, he must roll twice again, with
the GM again choosing the worst result. The psyker does not
roll twice on the Perils of the Warp table.
When manifesting a power at Push level, the psyker must roll
twice on both the Psychic Phenomena and Perils of the Warp
tables for each instance of either that is triggered. As above, the
psyker must roll twice again if he uses a Fate Point to reroll.
SLEEPING IN ARMOUR
A character who sleeps in armour risks being Fatigued upon
awakening. A character who sleeps in any type of armour must
make an Ordinary (+10) Toughness Test. If he was wearing a
body glove or mesh armour, he gains one level of Fatigue on a
failed Test. If he was wearing flak armour, he gains one level of
Fatigue on a success, or two levels of Fatigue on a failed Test. If
he was wearing carapace or power armour, he gains one level of
Fatigue on a success, two levels of Fatigue on a simple failure,
and three levels of Fatigue with two or more degrees of failure.
SIZE AND ATTACK RANGE
Creatures larger than Average have the following Range with
melee weapons, based on their size. Note that this assumes tall
creatures; long creatures (such as felids or hounds) have their
Range increased as if they were one size smaller.
Scrawny creatures stand under 1m tall, but still have a reach
(range with melee weapons) of 1m. Average creatures stand
between 1m and 2m tall, and have a reach of 1m. Hulking crea-
tures are 2–4m tall, with a reach of 2m. Enormous are 4–6m tall,
with a reach of 3m. Massive are 6–10m tall, with a reach of 4m.
Immense are 10–15m tall, with a reach of 6m. Monumental are
15–25m tall, with a reach of 8m. Titanic are 25–50m tall, with a
reach of 12m. Epic are over 50m tall, with a reach of 20m.
The minimum distance a creature must move in order to use
the Charge Action is equal to 3 plus its reach.
TWO-WEAPON WIELDING
Fighting with a weapon in each hand is popular amongst a wide
variety of cultures, organisations and combat styles. A character
wielding two weapons simultaneously suffers a –20 penalty to
all attack rolls, in addition to any other applicable modifiers.
(Note that if the individual does not have the Ambidextrous
talent, the penalty with his off-hand attacks will be a net –40.)
Simply holding a weapon in each hand does not impose this
penalty—a character counts as wielding two weapons only if he
makes an attack with both weapons during his Turn. This penal-
ty applies to all attacks made with either weapon until the start
of the character’s next Turn.
When wielding two melee weapons, a character may use the
Multiple Attacks Action to make a single attack with each
weapon. He cannot combine this with additional attacks granted
from any other source.
When wielding two ranged weapons, a character may use the
Multiple Attacks Action to make an attack with each weapon.
He may use any mode of fire (Single, Semi-Auto or Full Auto),
but must fire both weapons in the same mode.
A character cannot use a melee weapon and a gun together
unless he has at least one Two-Weapon Wielder talent.
When combining the Aim Action with the Multiple Attacks
Action (whether due to wielding two weapons, or as a result of
by Adrian Orlando Dark Heresy House Rules (v1.21) Page 3 of 9
using a talent such as Swift Attack), only the first attack a char-
acter makes each Turn benefits from the Aim Action.
TALENTS
Below is a list of new or updated (marked by *) Talents.
AMBIDEXTROUS*
Prerequisites: Agility 30.
You can use either hand equally well. You do not suffer any
penalty for using your secondary hand.
ARMOUR OF CONTEMPT*
Prerequisites: Willpower 35.
You drape yourself in the armour of scorn and hatred. Whenever
you would gain Corruption Points, reduce the amount you gain
by 1. This does not negate the automatic Corruption Point that a
psyker gains whenever he triggers Perils of the Warp.
AUTOSANGUINE*
Ancient and blessed technology filters your blood. Handed
down from generations past, your implants repair minor injuries.
For the purposes of removing Damage through natural healing,
your injuries are considered to be one step less severe than they
actually are (i.e. you treat Heavily Wounded as Lightly Wound-
ed, and you treat Critically Wounded as Heavily Wounded). In
addition, you naturally heal at an increased rate, removing one
extra point of Damage per time interval.
BALLISTIC MASTERY
Prerequisites: Ballistic Skill 45, Agility 40, Two-Weapon
Wielder (Ballistic).
You may use the Overwatch or Supressing Fire Action when
wielding two weapons capable of Full Auto fire, gaining the
usual effect with each weapon, except that you may only desig-
nate a single area. If you also have the Independent Targeting
talent, you may designate a separate area with each gun in line
with that talent. When using the Overwatch Action in this way,
you must take your Full Auto Burst Action with both weapons at
the same time (even if they are covering different areas).
Classes: Cost is the same as Two Weapon Wielder (Ballistic)
for a particular class, and only available two ranks later.
BATTLE RAGE*
Prerequisites: Frenzy.
You may Parry while frenzied, and you may choose not to use
the All-Out Attack Action. In addition, you may reroll a failed
roll to snap out of your frenzy or to resist entering a frenzied
state if you so choose.
BLADE DANCER
Prerequisites: Weapon Skill 40, Two-Weapon Wielder (Melee).
When wielding two single-handed melee weapons which do not
have the Unbalanced or Unwieldy quality, you reduce the penal-
ties for fighting with two weapons by a further 10 (usually re-
ducing the penalties to 0).
Classes: Cost is the same as Two Weapon Wielder (Melee)
for a particular class, and only available two ranks later.
BLADEMASTER*
Prerequisites: Weapon Skill 35, Melee Weapon Training (any).
Your mastery of sword and knife is unsurpassed, and your blade
always strikes true. When attacking with a bladed weapon of
any type, including chainswords, axes and power swords, you
may reroll a missed attack once per Round.
BLAST AWAY
Prerequisites: Ballistic Skill 35, Strength 35, Agility 35, Basic
Weapon Training (any).
You are practiced at using a Basic weapon in close quarters.
You may use any basic weapon which does not have the Accu-
rate quality or Long-Barrelled upgrade while engaged in close
combat, but suffer a –20 penalty on your Ballistic Skill Test.
You do not gain any other bonuses or penalties to hit for range
or targeting equipment. You may also apply this talent to a
weapon with the Flame quality, in which case all affected crea-
tures gain a +20 bonus on their Agility Tests to avoid injury.
Classes: Arbitrator, Assassin, Guardsman and Scum, 200 XP;
all others, 300 XP.
BULGING BICEPS*
Prerequisites: Strength 45.
Whereas a weaker man would be sent flying when using power-
ful weapons, your strong physique allows you to remain stand-
ing. You can fire a Heavy weapon on Semi-Auto or Full Auto
without first bracing; however, you take a –10 penalty on your
Ballistic Skill Test.
CATFALL*
Prerequisites: Agility 30.
You are nimble and balanced like a cat, and are able to fall
greater distances unharmed than others might. Whenever you
fall, you may make a Challenging (+0) Agility Test. On a suc-
cess, you treat the fall as your Agility Bonus in metres shorter,
plus one metre shorter per degree of success.
CRIPPLING STRIKE*
Prerequisites: Weapon Skill 40.
You are able to land your blows in the spot where they will in-
flict the most harm. Whenever you deal Critical Damage with a
melee attack, you deal an extra 2 points of Damage.
FAVOURED BY THE WARP*
Prerequisites: Willpower 35.
You may spend a Fate Point as normal to reroll results on TABLE
6–2: PSYCHIC PHENOMENA (doing so normally requires you to
burn a Fate Point).
Page 4 of 9 Dark Heresy House Rules (v1.21) by Adrian Orlando
FEARLESS*
The Fearless talent cannot be taken by player characters as an
advance.
FRENZY*
Prerequisites: —.
If you spend a Full Action fuelling your anger—by flagellation,
drugs or other means—on the next Round you go into an uncon-
trolled rage, gaining a +10 bonus to Weapon Skill, Strength,
Toughness and Willpower, but suffering a –20 penalty to Ballis-
tic Skill, Intelligence and Fellowship; this cannot reduce any
Characteristic to below 1. While frenzied, you must attack the
nearest enemy in melee combat if possible. If not engaged with
an enemy, you move towards the nearest enemy and engage it if
possible. You will not take obviously suicidal actions, such as
leaping off a building to engage an enemy on the ground, but
will take any actions that give you a reasonable opportunity to
engage in melee with the nearest enemy.
While frenzied, you are immune to Fear, Pinning, the effects
of Fatigue and cannot be Stunned, and you may not retreat, flee
or Parry. Where possible, you use the All-Out Attack Action to
attack your enemies. You remain frenzied for the duration of the
combat, and may not use psychic powers while frenzied.
After combat ends, or if there are no more eligible enemy tar-
gets for you to attack, you may make a Challenging (+0) Will-
power Test to snap out of your frenzy. If you fail, you must
attack the nearest ally (favouring NPCs over player characters).
At the start of your Turn each Round, you may make another
Willpower Test, with a cumulative +10 bonus, to return to a
stable state of mind and come out of your frenzy. You may not
enter a frenzied state again for at least one hour as you recover
your mental and physical strength.
GUN SCOUNDREL
Prerequisites: Ballistic Skill 40, Knave of Pistols, Pistol Train-
ing (any two).
You may now gain the Basic Weapon Training talent, but only
in classes of weapons in which you have the Pistol Training
talent. You still cannot gain the Heavy Weapon Training talent,
and you continue to take a –10 penalty on Ballistic Skill Tests
with all ranged weapons which are not Pistols.
Cost: 300 XP.
GUNSLINGER*
Prerequisites: Ballistic Skill 40, Two-Weapon Wielder (Ballis-
tic).
While wielding a pistol in each hand, you reduce the penalty for
fighting with two ranged weapons by 10.
HARDY*
Prerequisites: Toughness 40.
For the purposes of removing Damage through natural healing,
your injuries are considered to be one step less severe than they
actually are (i.e. you treat Heavily Wounded as Lightly Wound-
ed, and you treat Critically Wounded as Heavily Wounded).
HEAVY WEAPON TRAINING (CANNON)
Prerequisites: Heavy Weapon Training (any two).
You are proficient in the operation of military cannons, such as
the earthshaker and demolisher.
Classes: Guardsman and Tech-Priest, 200 XP; all others, 300
XP.
IMPROVED GRAPPLE
Prerequisites: Weapon Skill 35, Strength 35 or Agility 35.
You gain a +10 bonus on Tests related to grappling, including
the Weapon Skill Test to initiate a grapple and all Tests made
using the Grapple Action. You may take a single Grapple Action
as a Free Action immediately after you successfully initiate a
grapple with any opponent.
Classes: Arbitrator, Assassin, Guardsman and Scum, 200 XP;
all others, 300 XP.
JADED*
Prerequisites: Willpower 30.
You have seen the worst the galaxy has to throw at you to the
point that you are acclimatised to all but the worst of horrors.
You generally need not make Fear Tests against mundane hor-
rors (such as extremely violent deaths, excessive gore, vicious
beasts, and so on). You must still make Fear Tests as normal
against daemonic, xenos and psychic effects (which includes
sorcerous arcana, and all creatures with the From Beyond trait).
LIGHTNING REFLEXES*
Prerequisites: —.
You gain a +1 bonus on Initiative rolls. In addition, when rolling
for Initiative, you roll two dice and discard the lower result.
MARKSMAN*
Prerequisites: Ballistic Skill 35.
Distance is of little consequence with a gun in your hand, and
you are far more adept than most at picking off far away targets.
Increase the base range of any gun you wield by one-quarter,
rounded up to the nearest 5m; this does not apply to weapons
with the Spray quality. If the base range of the weapon is less
than 20m, instead round up to the nearest 1m.
PISTOL FINESSE
Prerequisites: Ballistic Skill 40, Agility 40.
You are adept at shooting up close and personal with a pistol.
When using a pistol in melee, you gain a +10 bonus on your
Ballistic Skill Test.
Classes: Arbitrator, Assassin, Guardsman and Scum, 200 XP;
all others, 300 XP.
PROSANGUINE*
Prerequisites: Autosanguine.
By an act of will, you speed the workings of your autosanguina-
tors. Once every twelve hours, you may make an Ordinary
(+10) Willpower Test. On a success, you heal Damage as if you
had just spent a Fate Point. If you roll a 96–00, in addition to
failing the Test, you overstrain your implants. They cease to
function for one week. During that time, you lose the benefits of
the Autosanguine talent and cannot use this talent. Using this
talent takes ten minutes of meditation and ritual incantation.
by Adrian Orlando Dark Heresy House Rules (v1.21) Page 5 of 9
RAGING ONSLAUGHT
Prerequisites: Weapon Skill 40, Frenzy, Swift Attack or Multi-
ple Arms trait.
When using the All-Out Attack Action, you may choose to make
multiple attacks, as if you had used the Multiple Attacks Action.
If you do, you gain a +10 bonus on all Weapon Skill Tests made
as part of that Action, instead of the usual +20 bonus. All other
benefits and restrictions of both Actions apply as normal.
If you wish to also gain the benefits of the Furious Assault
talent, you may use the Multiple Attacks Action with the All-
Out Attack Action, but gain no bonus on your Weapon Skill
Tests. The extra attack from Furious Assault applies to the first
successful attack you make.
Classes: Cost is 400 XP, and only available two ranks after
Frenzy.
RESISTANCE (DISEASES)
Prerequisites: Toughness 30.
You gain a +10 bonus on all Tests to resist the effects of disease.
Classes: Can be taken at the same rank and cost as Resistance
(Poisons).
RITE OF PURE THOUGHT*
Prerequisites: Mechanicus Implants.
You have begun the process of replacing the emotional centres
of your brain with cranial cogitators. You feel little emotion, and
are instead filled with the cold purity of logic. You gain the
Chem-Geld, Nerves of Steel and Resistance (Fear) talents.
SIDEARM
Prerequisites: Weapon Skill 40, Ballistic Skill 40, Two-Weapon
Wielder (Melee), Two-Weapon Wielder (Ballistic).
When armed with a pistol in one hand and a one-handed melee
weapon in the other, you reduce the penalties for fighting with
two weapons by a further 10 (usually reducing them to 0).
Classes: Cost is same as Two Weapon Wielder for a particu-
lar class, and only available two ranks later.
SNIPER’S POSE
Prerequisites: Ballistic Skill 30, Agility 30, Basic Weapon
Training (any).
You are adept at using the sniper’s pose (laying out prone on the
ground) to maximum effect. You may assume the sniper’s pose
while using a Basic weapon by intentionally adopting a prone
position as a Half Action. If you take any Action other than
shooting (includes Overwatch and Suppressing Fire), Aim, De-
lay, Focus Power or using relevant skills (such as Awareness to
spot new targets or Concealment to hide again after sniping),
you lose the benefits of being in the sniper’s pose, and must
spend a Half Action again to readopt the pose. While in a snip-
er’s pose, you suffer no penalty on Ballistic Skill Tests for being
prone, and enemies at a distance further than Point Blank suffer
a –10 penalty on ranged attacks against you.
Classes: Assassin and Guardsman, 100 XP; Arbitrator and
Scum, 200 XP; all others, 300 XP.
TARGET SELECTION
Prerequisites: Ballistic Skill 50.
Your dread gaze marks out your chosen victim, and not even the
riotous confusion of close combat interferes. You reduce the
penalty for shooting into melee by 10.
Classes: Arbitrator, Assassin, Guardsman and Scum, 100 XP;
all others, 200 XP.
THUNDER CHARGE
Prerequisites: Strength 50.
You charge into combat, using your body as an additional wea-
pon to push foes away or to the ground. When you use the
Charge Action, you may barrel through foes to get to your tar-
get. Make an Opposed Strength Test with each foe in the way,
adding each creature’s size modifier to its roll. Any foes with
the Sturdy trait add the usual +20 bonus to their rolls. Foes who
fail their rolls are knocked prone. If you fail by two or more
degrees, you are instead knocked prone. Once you have knocked
down all those in your way, you may complete your Charge and
make your attack against your intended target.
Classes: Arbitrator, Cleric, Guardsman and Tech-Priest, 200
XP; all others, 300 XP.
TOUCHED BY THE FATES*
Prerequisites: Free-willed, living, non-daemonic Non Player
Character.
The Non Player Character has a number of Fate Points equal to
half its base Willpower Bonus (round up); the Unnatural Will-
power trait does not increase the number of Fate Points that the
NPC gains. These Fate Points may be used in exactly the same
way as for Player Characters. In addition, the rules for Right-
eous Fury also apply to this Non Player Character.
At the Game Master’s option, some NPCs (such as Inquisitors
or Space Marines) may gain additional Fate Points from this
talent.
TWO WEAPON WIELDER*
Talent Groups: Ballistic, Melee.
Prerequisites: Agility 35, Ballistic Skill 35 or Weapon Skill 35.
You reduce the penalty for fighting with two weapons by 10, to
–10 instead of the usual –20. You may make a single attack with
one hand, in addition to any attacks you are normally entitled to
make with the other.
When attacking with two ranged weapons, you may use dif-
ferent modes of fire for each weapon.
When wielding a gun and a melee weapon together, if you
have only the Two Weapon Wielder (Ballistic) talent, you may
use the Multiple Attacks Action to make a single attack with the
melee weapon, and to fire the gun in any mode of your choice. If
you have only the Two Weapon Wielder (Melee) talent, you
may instead make any attacks you are normally entitled to with
the melee weapon (such as from the Swift Attack talent), but can
only fire the gun in single shot mode. If you have both Two
Weapon Wielder talents, you may make any attacks you are
normally entitled to with the melee weapon and fire the gun in
any mode of your choice.
Page 6 of 9 Dark Heresy House Rules (v1.21) by Adrian Orlando
WEAPONMASTER
Prerequisites: Weapon Skill 40, Blademaster.
Your mastery of melee combat is unsurpassed, and your weap-
ons almost always strike true. When attacking with any non-
bladed melee weapon that does not have the Unwieldy quality,
you may re-roll a missed attack once per Round. You cannot
benefit from both the Blademaster and Weaponmaster talents in
the same Turn.
Classes: Cost is same as Blademaster for a particular class,
but is only available one rank later.
TRAITS
Below is a list of new or updated (marked by *) Traits.
AUTO-STABILISED*
The creature may use Heavy weapons without needing to brace
them first. In addition, the creature may take a single Half Move
Action as part of making a semi-auto or full auto attack with any
personal ranged weapon (Basic, Heavy or Pistol).
DAEMONIC (+X)*
Daemonic creatures are creatures of the warp, but can manifest
in realspace either through sheer strength of will, hunger or oc-
cult rituals. Creatures with this trait increase their Toughness
Bonus by X against all Damage, except for Damage inflicted by
weapons with the Force or Warpbane quality, psychic powers or
other creatures with this trait.
DEADLY NATURAL WEAPONS
The creature has razor-sharp claws, adamantium-hard fists or
some other similarly lethal natural weapon. The creature must
have the Natural Weapons trait in order to gain this trait.
The creature’s natural attacks loses the Primitive quality.
PENETRATING BLOW (+X)
The creature’s specified natural attack can punch through ada-
mantine and ceramite. The creature must have the Natural
Weapons trait in order to gain this trait.
The creature’s natural attacks add +X to Penetration.
QUADRUPED (+X)
The creature has multiple sets of legs, allowing it to scamper
across terrain faster and more stably than bipeds can.
Increase the creature’s base movement rate by X; the value of
X is generally equal to the number of pairs of legs than the crea-
ture has (e.g. +2 for four-legged creatures, +3 for six-legged, +4
for eight-legged, and so on), to a maximum value of 8.
REGENERATION (X)
The creature heals with unnatural speed.
Each Round, at the start of its Turn, the creature makes a
Challenging (+0) Toughness Test. On a success, it removes 1
point of Damage, plus 1 point for every degree of success, to a
maximum equal to the value X.
If the creature is currently suffering from Critical Damage, it
instead removes that many points of Critical Damage per hour.
RENDING STRIKE
The creature’s specified natural attacks can cause debilitating
injuries, and leave only shredded flesh and twisted metal in their
wake. The creature must have the Natural Weapons trait in order
to gain this trait.
The creature’s natural attacks gain the Tearing quality.
SPRINTER
The creature is a natural sprinter, able to hit full speed quickly
and maintain it longer than most other creatures.
The creature gains the Sprint talent, and does not automatical-
ly gain Fatigue when using the Sprint talent. Instead, on the
second Round, the creature must make an Ordinary (+10)
Toughness Test; on a failure, it gains one level of Fatigue. In-
crease the Difficulty of the Test by one step for each subsequent
Round the creature continues to use the Sprint talent. After-
wards, the creature must rest for one full minute before it can
use the Run Action or the Sprint talent.
STRANGE PHYSIOLOGY*
As per the DARK HERESY CORE RULEBOOK; additionally, the
creature is immune to disease, poison, Stunning and does not
need to breathe.
SUREFOOTED
The creature is naturally surefooted when moving over rough or
unstable terrain.
The creature gains a +20 bonus on Agility Tests made to
move through treacherous terrain.
TAINTED NATURAL WEAPONS
The creature’s natural attacks are tainted by the warp. The crea-
ture must have the Daemonic or From Beyond trait, as well as
the Natural Weapons trait, in order to gain this trait.
The creature’s natural attacks lose the Primitive quality and
gain the Tearing quality. Increase the Penetration of the crea-
ture’s natural attacks by +2.
UNNATURAL CHARACTERISTIC (+X)*
One or more of the creature’s Characteristics is unnatural. The
creature’s Characteristic Bonus increases by X.
Applying this trait to a creature’s Agility does not increase its
movement. Movement is based on a creature’s unmodified Agil-
ity. See the Unnatural Speed trait for increased Movement.
Whenever the creature makes a Characteristic Test (whether
opposed or not), reduce the Difficulty of the Test by one step,
plus one step for every four points of increased bonus. For ex-
ample, Opposed Tests are usually Challenging (+0), but a crea-
ture with Unnatural Strength (+1) would instead make an Ordi-
nary (+10) Test against its opponent’s Challenging Test; if that
same creature had Unnatural Strength (+4), it would instead
make a Routine (+20) Test.

Bonus by X.
LORE SKILLS
Below is an updated list of Lore skills, with descriptions of what
new skills cover.
COMMON LORE
This skill does not represent scholarly training, nor obscure for-
bidden knowledge, but rather the basics you learn by growing up
in, or travelling extensively through, a region.
A character never risks gaining Corruption or Insanity points
by making a Common Lore Test.
Adeptus Arbites: Knowledge of the various divisions and
arms of the Arbites, including such things as their ranking struc-
ture and common procedures.
Administratum: Broad knowledge of the inner workings,
rules and regulations of the Administration.
Ecclesiarchy: Understanding of the hierarchy of the Cult of
the Emperor, and its rankings, greetings and general practices.
Imperial Creed: Knowledge of the rites and practices of the
Imperial Cult, the most common observances to the Emperor,
and the most well-known saints.
Imperial Guard: Basic knowledge of famed regiments and
commanders of the Imperial Guard, standard practices of Impe-
rial Guard forces and commonly used weapons, vehicles and
equipment.
Imperial Navy: Basic knowledge of famous admirals and
ships of the Imperial Navy, standard practices of Imperial Navy
forces and commonly used weapons, vehicles and ship types.

well-known worlds of the Imperium.

practices of the Adeptus Mechanicus, as well as such things as
formal greetings and identifying rankings.

dominant characteristics of the preeminent noble families of the
Imperium, including Navigator families.

tions outside the Calixis Sector are Hard (–20).
Acolytes may select additional Common Lore skills not usual-
ly available to them as elite advances, at a cost of 150 XP each.
FORBIDDEN LORE
This skill represents dangerous and often heretical knowledge,
gleaned from the myriad of unconventional, and even outright
proscribed, sources that an Acolyte often finds in his possession.
This skill represents a combination of scholarly learning and
knowledge gained through practical experience. Simply pos-
sessing a Forbidden Lore skill is often sufficient to warrant ter-
mination at the hands of the Inquisition, and a character must
tread carefully when revealing such knowledge.
A character who fails a Forbidden Lore Test by three or more
degrees must pass a Challenging (+0) Willpower Test to avoid
gaining 1d5 Corruption and/or Insanity Points (GM discretion).
For every additional degree of failure on the Forbidden Lore
Test, increase the Difficulty of the Willpower Test by one step.
The character gains an additional Corruption and/or Insanity
Point for every degree of failure on his Willpower Test.
Adeptus Astartes: Basic knowledge of the ranks, customs,
insignia and famous engagements of the Space Marine Chapters.
Adeptus Custodes: Basic understanding of the duties, cus-
toms and ranks of the Emperor’s personal guard.

some of their sub-sects and splinter cabals. Information regard-
ing less common cults is more difficult to discover or recall.
Daemonology: Terrible comprehension of some of the rec-
orded warp entities and their various manifestations.
Heresy: Unpleasant appreciation for those acts and practices
deemed heretical by the Imperium, the most contemptible here-
tics of history, and their most infamous acts.
Inquisition: A general understanding (often based on hearsay
and rumour) of that most terrible and secretive of organisations,
known as the Inquisition.
Legend: Going beyond archaic knowledge, this encompasses
the most secretive portions of the Imperium’s history, such as
the Dark Age of Technology, the Age of Strife, the Horus Here-
sy and the Forgotten Apocalypse. This knowledge is hidden and
only known to a few, and is usually proscribed and/or heretical.
Mutants: Covering the study of both stable and unstable mu-
tations, and some of their more unfortunate results.
Navigators: Secret knowledge about the Navis Nobilite fami-
lies, their breeding programs, common mutations and prominent

eddies can affect travel between the stars.

Imperium, the threat they pose and their general appearance.
Information regarding minor alien species is more difficult to
discover or recall.
Acolytes may select additional Forbidden Lore skills not usually
available to them as elite advances, at a cost of 100 XP each (as
a basic skill) or 300 XP each (as a trained skill); Adepts and
Clerics pay only 200 XP each for additional trained skills.
Tech-Priests gain Forbidden Lore (Tech) as a starting skill,
and may take advances in this skill at the same rank and cost as
the Tech-Use skill. They may gain training and take advances in
Forbidden Lore (Tech-Heresy) at the same rank and cost as the
Forbidden Lore (Archeotech) skill.
SCHOLASTIC LORE
This skill represents scholarly knowledge of a particular subject.
In some areas, Scholastic Lore overlaps with Common Lore or
Forbidden Lore, but almost always represents a far greater—and
more academic—level of study.
A character who fails a Scholastic Lore Test to recall infor-
mation regarding a proscribed or dangerous topic by three or
more degrees pass a Challenging (+0) Willpower Test to avoid
gaining 1 Corruption and/or Insanity Point (GM discretion). For

Chymistry: A knowledge of chemicals, their alchemical ap-
plication, and their use throughout the Imperium.
Cryptology: An understanding of codes, ciphers, secret lan-
guages and numerical keys. This may be used to either create or
decipher encryptions.

Philosophy: Knowledge concerning the theories of thought,
belief, existence and other intangibles. As it also includes logic

of Trade, well-known deeds associated with them, their bearers,
and the vessels carrying them through the Imperium.

grant that individual a +10 bonus on one other Test during the
current battle. For every degree of success, one other ally gains
the same benefit.

sations based outside the Calixis Sector are Difficult (–10), with
