The following items are common mistakes, omissions, or useful pieces of information for 40k armies. Thank you to everyone that contributed I am trying to focus on prohibitions and generally negative attributes. The items are taken from FAQs, codices, and the rule book. However, be sure to consult with tournament organizers to see if tournament rules will replace GW FAQs and rules (e.g. the NOVA Open in the U.S. ruled that vendetta wings and tails could hang off the table and the INAT erroneously identifies the Lash of Submission as a psychic shooting attack). Be aware that some of the rules listed below can be affected by unit upgrades (e.g., battlewagons can pay for an upgrade to remove the open-topped rule). I would be grateful for help fact-checking the list.

General Rules
1. You may not go back and move units that have already moved once you have started moving another unit.
2. Squadron rules change immobilized to wrecked, stunned to shaken
3. Passengers cannot fire from an opened topped vehicle if it moves over 6".
4. Falling back units cannot rally if an enemy unit is within 6"
5. Successful invulnerable saves against perils of the warp must be rerolled.
6. A fast vehicle cannot move flat out on the same turn that a unit embarks or disembarks from it; skimmers that moved flat out and suffer an immobilized result are wrecked.
7. A unit may not assault from a vehicle that pivoted before they disembarked.

10. A vehicle with PotMS cannot fire a weapon on the turn it uses smoke launchers.

Grey Knights:
1. Can either cast hammerhand or activate force weapons--not both unless one comes from IC or upgrade character
2. Crowe is not an IC; his heroic sacrifice requires psychic test (so no hammerhand/cleansing flame in the same phase) and can be hooded.
3. Perils of warps kills the justicar first, then a random marine if the justicar is dead.
4. GK terminators are LD9; strike squads are LD8 without justicar!

2. A Farseer on a jetbike cannot cast psychic powers on the same turn that it turboboosts.

7. If a tank is destroyed, any attached drones may not disembark and are destroyed, but do not give an additional Killpoint.

9. If there is more than one RP in the army, they have to be given different powers and different weapon load-outs. The most common weapon load-out being swapping the standard bolt pistol for a boltgun. This way that RP loses an attack in CC for not having two CC weapons.
10.

TYRANIDS
1. Synapse range is 12"
2. Genestealers do not have grenade equivalent for assaulting into cover.
3. Shadow in the Warp has a 12" range and does not affect psykers in vehicles (lolwut!?)

8. Necrons can teleport out of CC with veil using deep strike, and by using the monolith (The squad must be partially within 24 inches of the monolith. aka 5 out of a squad of 10 must be within 24 of the monolith).

9. A monolith can't move if it is stunned, and can't shoot it's Gauss flux arc if it's shaken or stunned. A monolith can't shoot it's Gauss flux arc and particle whip at the same time, nor can a monolith use it's portal and it's particle whip in the same turn.
10. Nightbringer essentially has a lascannon; C'tan have a 4++ invul, are not fleet, do not have eternal warrior and are 300 and 360 points respectively.


Black Templar
1. Yes the Emperor's Champion with "Accept any Challenge" gives the army preffered enemy, but they also MUST assault if they can. This can be avoided by shooting with rapid fire/heavy weapons.
2. All Black Templar units are FEARLESS in assault.
3. Stormshields are now a 3++, but also cost the appropriate 15 pts.
4. Any vehicle (not Speeders) can be given Power of the Machine Spirit. It is also the Power of the Machine Spirit from the current Space Marine Codex.
5. The Emperor's Champion must get into Base to Base with an enemy ICs if his movement allows. Any friendly models in the way move out of the way.
6. Marshals and so (sanctity, reculsiarch, etc) in the HQ squads are not retinues and may not leave the squad, but are always considered IC's.
7. Crusader squads consist of normal marines (Initiates) and scouts (neophytes) and can take a Land Raider Crusader as a Dedicated Transport. LRC can take blessed hull to ignore the Lance rule.
8. Cyclone Missile Launchers are heavy 2 missile launchers. Typhoon Missile Launchers are also 2 missile launchers (but fires as one weapon).
9. Smoke now gives a 4+ cover save not all pens are glances
10. BT units may roll using the Marshal/Castellans leadership should they choose to only if he is alive. Also they must pay for Frag/Krak grenades. Only HQ squads have sergeants

Dark Angels:

1. Attack bikes are scoring units when taken as add-ons to bikers; the same applies to land speeders as part of a Ravenwing Attack Squad.
2. Deep striking terminators do not scatter when within 6'' of bikes (all come standard with beacon). Model must be placed first and then measurements taken.
3. Up to half of the reserved terminator squads may be brought in by deepstrike in turn 1. This does not have to be declared until turn 1.
4. Ravenwing bikes have a scout move. This means that if given first turn, the bikers can move 24'' (12'' scout + 12'' movement) and still fire. (Ye be warned Landraiders).
5. Ravenwing bikers CANNOT turbo boost as their scout move.
6. All terminators and bikers are fearless.
7. Belial makes terminators a troop choice when he enters the army.
8. When taking an apothecary, cyclone and standard bearer with Belial's terminator squad. There are six different model types in the squad. (Creates a wound distribution advantage)

10. Belial is WS5 with 3W

Space Marines.

1. Chapter tactics over writes combat tactics.
2. Only a captain can take a command squad
3. drop pods cant fire when they arrive
4. drop pod occupants take dangerous terrain if they enter terrain disembarking
5. Special sternguard ammo does not work with pistols only boltguns
6. Vortex of doom hits the librarian on a failure to cast, not perils
7. servo arms strike at strength 8, no modification; relic blades strike at strength 6, no modification
8. gate of infinity is used at the start of the movement phase, so cannot gate a non troop unit in dawn of war
9. units cannot comabt squad while in reserve (2 transports, etc)
10. locator beacons cannot be premeasured to

Sisters of Battle

1. The only long range anti mech firepower in the codex is the Exorcist, disabling the exorcists is key to winning, do this any way you can.
2. Sisters of Battle have a hard time VS mass 2+ saves, they don't have the high volume of shots, or access to a lot of plasma to kill elites. Flamers suffer when there's only 4-5 targets
3. Sisters of Battle excel at short range shooting (within 12 inches). Use this to your advantage and stay back and kite.
4. Immolators can only move 6 and fire their heavy flamers, same with multi melta.
5. If your opponent is running Celestine, chances are they'll run it at your objective and try and contest your obj by bringing her back. Also, she's a very very mean tarpit, do not assault her unless you have to. She is not eternal warrior and is T3
6. Seraphim hand flamers are only str 3 ap 6, they have a 6+ rerollable invul, and they can reroll their wounds with flamers and bolt pistols.
7. Death Cult/Jacobus does not have fleet, do not assault this squad, shoot it to death. Jacobus cult is most likely the nastiest assault unit in the game atm.
8. Dominion squads can outflank, and infiltrate, prepare for this. Also if a character joins the dominion squad, they do lose their scouts rule. Dominions can carry 5 flamers or 5 melta with TL. Take these out as quick as they come on the board.
9. Faith can only be used on the Sister player's turn.
10. Jacobus lets a Sister player reroll the amount of faith points per turn, he DOES NOT allow the player to reroll their faith checks.

I like how TC Decided the reminders should be 10 yet only listed 4...

Everything but SW and GK
1.Your not as good.

BA:

BA MUST re-roll failed reserved when entering play from deep strike via DoA

Sang Priests are independant characters

Land raiders can deepstrike but can mishap like anything else

VVets HAVE to declaire before coming in if they'll intervene or not.

Tau:
yes that 5pt upgrade does give me a 4+ cover save.

Phototoxin wrote:BA:

BA MUST re-roll failed reserved when entering play from deep strike via DoA

This is incorrect. The codex specifies that "Any unit with this special rule can re-roll failed reserve rolls if arriving by Deep Strike." Not must.

Perhaps it is best to let TOs make such decisions regarding rules, and leave it to the players to ask ahead of time how they would interpret the rules of their army based on Codices, FAQs, and other such things.

Remember, there are things such as opinions, but the tourney organizers and their judges turn opinion into law for their events, no matter what you say.

Tau:

1.You do not get cover saves from markerlights.
2.Markerlights can only increase BS to 5
3.Drones connected to a unit of Firewarriors DO count toward squad size (E.g. if they make the unit more than 12, they're no getting in the Devilfish)
4.If the vehicle has drones on its turrets, and has moved far enough to shoot only one weapon, the drones can still shoot along with one of the fish's weapons.
5.Broadsides cannot drop a large blast like a Hammerhead
6.Kroot have Leadership 7 without their Shaper
7.Farsight does not permit more than one of anything that isn't Firewarriors, Crisis Suits, or Devilfishes
8.Farsight also does not allow use of Ethereals, Vespid, and Kroot at all
9.Ethereals only gives bonuses to Tau units if they are within LOS to the Ethereal
10.A commander with only gundrones still counts as an independant character, as in he can join/separate from units with his drones.

11.Krootoxes count as 2 units when loading into a transport

What nonsense. If TOs want to make rules decisions that disregard FAQs (e.g., NOVA and vendetta bases) that is their discretion. What I'm interested in is creating a useful reference document for players based on the existing rules and FAQs.

IG:
1) Orders must be done first before any other shooting, and must be done from most to least senior.
2) Five weapons can shoot out of a chimera hatch
3) Leman Russ executioners can shoot up to five plasma cannon shots a turn
4) Artillery is open topped, but hydras and Manticores are not
5) Marbo does not scatter when he appears, and has a demo charge.
6) Valks/Vendettas get a 4+ cover save after a scout move >12"
7) Units can disembark anywhere within 2" of the base of a valkyrie
8) Commissars make any unit they're attached to LD9 and Stubborn, and are not independent
9) Hydras have 72" range
10) Guardsmen have frag grenades, making them S4 against vehicles. Veterans have Krak standard.

Orks:

1 - If the Ork player is going first, their Deffkopta can assault you with its buzzsaw turn 1. No, I don't care that you're all the way in the corner.
2 - If a battlewagon RAMS, it can roll your vehicle and tank shocks units on the way.
3 - If a battlewagon TANK SHOCKS, it stops in front of any vehicle. They need to declare a direction and a distance before they measure anything.
4 - Ghazghkull gives orks in cars a ~28" charge range, plan accordingly.
5 - Burnas in a battlewagon will ruin your day, but can only burn you if they move 7" or less.
6 - The KFF gives infantry a 5+ and vehicles a 4+. If it's a squadron, half or more of them need to be in range.
7 - Ork vehicles with boarding planks (and someone inside) can make CC attacks on both players' combat phases, and can strike dreadnoughts. No, he doesn't get to swing back.
8 - Lootas are dangerous, but their leadership is tripe. Shoot them enough to force a leadership test and move on.
9 - Boyz are very very dangerous on the charge, but much more managable without. Find a way to charge THEM and you're well on your way to winning.
10 - If a battlewagon EXPLODES your vehicle, it keeps going. This means that if it explodes a transport and has more movement, it probably tank shocks the guys inside, too. Note that this is not true if it merely WRECKS your vehicle.

An addendum:

2 - If a battlewagon RAMS, it can roll your vehicle, counts as moving cruising speed regardless of actual movement and tank shocks units on the way.

4 - Ghazghkull gives orks in cars a ~28" charge range, plan accordingly.

7 - Ork vehicles with boarding planks (and someone inside) can make CC attacks on both players' combat phases, and can strike dreadnoughts. No, he doesn't get to swing back.

For IG and GKs, I think the two things are important so please make room for them in the top 10 if you agree:

GK:

Coteaz's manipulation of Seize the Initiative.

GKGM Grand Strategy allows scoring dreads, and list what it can actually do (I don't know, but it's important and out-of-the-box)

IG:

Officer of the Fleet gives -1 to enemy reserve rolls and can force reroll on outflank. Astropath gives +1 to controlling player's reserve rolls and can option reroll on outflank.

Dark Eldar

1. While all vehicles are fast, embarked squads can still only fire if they have moved 6" or less. Aerial Acrobatics has no effect.
2. Splinter Cannons on infantry can shoot at assault 4 OR heavy 6 while vehicle MUST use the heavy 6 version.
3. Venoms come with the Flickerfield upgrade standard so just because they didn't declare the upgrade at the begining doesn't mean it isn't there.
4. If a voidraven turboboosts it can still drop its Void Mine. It can also shoot at a different target then the one it dropped its mine on.
5. Haemonculi, Talos, Chronos, Wracks, Grotesques, and Urien DO NOT have fleet.
6. Razorwings and Voidraves are NOT open-topped.
7. Raiders are very pointy thus a crafty DE player can assault 37"-42" (12" deploy, 12" move, 3" pivoting after move, 2" disembark, 1" base size, 6" assault, d6" run) with wyches...plan accordingly.
8. Drugs MUST be rolled for before the game. Duke Sliscus allows two rolls then the DE players choice applies.
9. Only models with Power from Pain get any benefit from pain tokens. So this means that Beasts are unaffected from the token while Beastmasters are not.
10. Models arriving via Duke Sliscus' "Low Orbit Raid" can dissembark from transports to shoot/run. Note that this is different from the vehicle upgrade "Retrofire Jets". This however does not mean that they can assault that turn as they still count as having Deep Striked.

Black Templar
1. Yes the Emperor's Champion with "Accept any Challenge" gives the army preffered enemy, but they also MUST assault if they can. This can be avoided by shooting with rapid fire/heavy weapons.
2. All Black Templar units are FEARLESS in assault.
3. Stormshields are now a 3++, but also cost the appropriate 15 pts.
4. Any vehicle (not Speeders) can be given Power of the Machine Spirit. It is also the Power of the Machine Spirit from the current Space Marine Codex.
5. The Emperor's Champion must get into Base to Base with an enemy ICs if his movement allows. Any friendly models in the way move out of the way.
6. A Marshal/Castellan and a Master of Sanctity/Reclusiarch (Captain and Chaplain) can be joined to a command squad and counts as 1 HQ choice. They are also not ICs as long as the squad is alive.
7. Crusader squads consist of normal marines (Initiates) and scouts (neophytes) and can take a Land Raider Crusader as a Dedicated Transport. LRC can take blessed hull to ignore the Lance rule.
8. Cyclone Missile Launchers are heavy 2 missile launchers. Typhoon Missile Launchers are also 2 missile launchers (but fires as one weapon).
9. Black Templars must test at -1 to their Leadership in order to not shoot at the nearest enemy unit.
10. Smoke now gives a 4+ cover save not all pens are glances
11. I know its an extra but it is kinda important. BT drop pod assault does not allow for first turn arrivals they are reserves as normal.
12. Last one...BT units may roll using the Marshal/Castellans leadership should they choose to only if he is alive. Also they don't have Sergeants or Frag/Krak grenades.

Cool list. If any of you can agree that some of these are
definitive, we could make them articles.

I really only have one, it's for necrons (because for some reason this always comes up):

1. The monolith can't use both the particle whip and the teleport portal in the same turn

Sisters of Battle

1. The only long range anti mech firepower in the codex is the Exorcist, disabling the exorcists is key to winning, do this any way you can.
2. Sisters of Battle have a hard time VS mass 2+ saves, they don't have the high volume of shots, or access to a lot of plasma to kill elites. Flamers suffer when there's only 4-5 targets
3. Sisters of Battle excel at short range shooting (within 12 inches). Use this to your advantage and stay back and kite.
4. Immolators can only move 6 and fire their heavy flamers, same with multi melta.
5. If your opponent is running Celestine, chances are they'll run it at your objective and try and contest your obj by bringing her back. Also, she's a very very mean tarpit, do not assault her unless you have to. She is not eternal warrior and is T3
6. Seraphim hand flamers are only str 3 ap 6, they have a 6+ rerollable invul, and they can reroll their wounds with flamers and bolt pistols.
7. Death Cult/Jacobus does not have fleet, do not assault this squad, shoot it to death. Jacobus cult is most likely the nastiest assault unit in the game atm.
8. Dominion squads can outflank, and infiltrate, prepare for this. Also if a character joins the dominion squad, they do lose their scouts rule. Dominions can carry 5 flamers or 5 melta with TL. Take these out as quick as they come on the board.
9. Standard Battle Sisters are now very very weak in CC. They do not have stubborn now unless attached to a character. It's very easy to make them break and run in CC, then sweeping advance, because they're only int 3.
10. Jacobus lets a Sister player reroll the amount of faith points per turn, he DOES NOT allow the player to reroll their faith checks.
11. Faith can only be used on the Sister player's turn.

Here Goes One Important thing I know:
Tyranids:
1: Although Genestealers do not suffer from instinctive behavior, they still recieve the bonuses if they are within synapse range.

1 - If the Ork player is going first, their Deffkopta can assault you with its buzzsaw turn 1. No, I don't care that you're all the way in the corner.
2 - If a battlewagon RAMS, it can roll your vehicle, counts as moving cruising speed regardless of actual movement and tank shocks units on the way.
3 - If a battlewagon TANK SHOCKS, it stops in front of any vehicle. They need to declare a direction and a distance before they measure anything.
4 - Ghazghkull gives orks in cars a ~28" charge range, plan accordingly.
5 - Burnas in a battlewagon will ruin your day, but can only burn you if they move 7" or less.
6 - The KFF gives infantry a 5+ and vehicles a 4+. If it's a squadron, half or more of them need to be in range.
7 - Ork vehicles with boarding planks (and someone inside) can make CC attacks on both players' combat phases, and can strike dreadnoughts. No, he doesn't get to swing back.
8 - Lootas are dangerous, but their leadership is tripe. Shoot them enough to force a leadership test and move on.
9 - Boyz are very very dangerous on the charge, but much more managable without. Find a way to charge THEM and you're well on your way to winning.
10 - If a battlewagon EXPLODES your vehicle, it keeps going. This means that if it explodes a transport and has more movement, it probably tank shocks the guys inside, too. Note that this is not true if it merely WRECKS your vehicle.

Only thing I want to add here is that any unit with Ghazghkull must always roll for difficult terrain including assaults (I've seen this missed quite a few times)

Since no one has done it yet.

Necrons

1. Shoot the destroyers first at range, they're only T5 with a 3+ save, considering the amount of damage they do, this should be priority. Destroyers count as jet bikes for ALL purposes.
2. Ignore the Monolith unless you've got str 10, chances are you're going to spend all game bouncing shots off it you could have used to put down destroyers.
3. Necrons are horrible at taking objectives because most take very low troops (never usually more than 3) cripple their troops after killing the destroyers in objective games. Phase out count is usually anywhere from 7-12 models
4. If there is a tomb spider or two kill them first with your heavies. It's only a T6 MC with no invul and 2 wounds. With the tomb spider dead, now if you knock down a whole squad, it stays down (unless within 6 inches of a squad of the same type) Tomb spider's range also, is only 12 inches.
5. Get in CC with Necrons, even if you're a horrible CC army like IG, at long as you have at least 1 power weapon, chances are you'll win combat and sweeping advance the Necrons with their INT 2. Necrons get no WBB from sweeping advance.
6. If there are heavy destroyers, kill them after tomb spiders, they are the only unit to be able to pen armor at long range.
7. Getting vehicles close to Warriors, even in 5th is somewhat devastating sometimes. Enough glances can do some major damage, doesn't matter if it's armor 10, or 14.
8. Necrons can teleport out of CC with veil using deep strike, and by using the monolith (The squad must be partially within 24 inches of the monolith. aka 5 out of a squad of 10 must be within 24 of the monolith). Also using the monolith they can reroll their WBB saves to give them something like an 80% chance for the squad to fully get back up. This is why killing tomb spiders is vital.
9. A monolith can't move if it is stunned, and can't shoot it's Gauss flux arc if it's shaken or stunned. A monolith can't shoot it's Gauss flux arc and particle whip at the same time, nor can a monolith use it's portal and it's particle whip in the same turn.
10. Both of the Ctan die very easily to anything str 7 or above, auto cannons even force a 4+ invul. However, if a Ctan is not near you, don't shoot it, ignore it. They are very slow and take a long time to get anywhere, even when running.

Space Wolves
1. Everything has counterattack
2. Half of Njal's abilities don't work if going second
3. Njal is pronounced Nigel (cause its funnier that way)
4. TWC are base toughness 5, meaning they don't take a lot of wounds.
5. Everything has counterattack (in case you forgot)
6. Every space wolf army will contain 3 squads of long fangs. Its mandatory just like fire warriors for tau.
7. Wolf Guard terminators cannot join scouts
8. Wolf Guard are not ICs
9. Wolf Standards activate for the NEXT assault phase
10. Everything has counterattack

@Timmah

You've been on here a long time. I don't believe you missed the most important thing when playing Space wolves! Everything has counter attack

Great idea for a thread.

Very useful.

CSM:
1) Lash of Submission is not a psychic shooting attack.
2) Obliterators are Slow and Purposeful, which also means they can move or deep strike and fire a heavy weapon in the same turn.
3) Obliterators do not have Terminator Armour, they simply have a 2+ save as standard and can therefore Sweeping Advance.
4) Plague Marines are T4(5) not T5.
5) Warptime and Gift of Chaos are used at the start of the turn (or turns in the case of Warptime), before movement.
6) Chaos Land Raiders do not have PotMS.
7) Defilers have the Fleet USR.
8) Chaos Terminators are not Fearless.
9) The Chaos Terminator Champion upgrade can be taken on as many terminators as are in the squad, it is not a unqiue squad leader upgrade like Aspiring Champions are.
10) Chaos Space Marines have Bolters, Bolt Pistols, and CCWs as standard.

I had a huge debate on the YMTC forum about the speed of any Ramming Vehicle. Pg 68, par 6, line 2, TANKS: Tank Shock!: "The vehicle must move at least combat speed". My argument was that they should be considered as having moved at top speed no matter how far they moved, but I cannot come up with an argument to convince the rules lawyers who think that distance traveled is the absolute measurement of speed. If you have an idea that I haven't tried, please let me know.

Reguarding TankShock or Ramming. If the Vehicle doing the attack moves less than Flatout, you may still fire weapons as normal after the tankshock/ram.

Eldar List
#1 Psychic powers are done before any movement, except of course the ones in the shooting phase.
#2 If you get a peril of the warp, you must reroll the successful ghosthelm save unless you fortuned yourself first.
#3 If a peril makes it past the ghost helm, you get your invuln save.
#4 If you have an Embolden Warlock with your Farseer, don't forget to reroll all failed psychic tests and avoid #2 and #3
#5 Begin every List with Eldrad
#6 Harlequins do not roll for moving or assaulting through cover, ever.
#7 Fortune your Avatar
#8 Eldrad is no slouch in CC
#9 Yes Swooping Hawks can bounce off the table right after tossing a pie plate template, if they have Skyleap.
#10 Take cheapest load out for tanks, on average they will be shaken every turn, if you took the stones and holofields.

#11 Note to self, Guiding a vehicle with twin linked weapons is a real waste of a pyschic power.

Surely that's if they move over 18" (fast, skimmer rules)

8) Commissars make any unit they're attached to LD9 and Stubborn, and are not independent
9) Hydras have 72" range
10) Guardsmen have frag grenades, making them S4 against vehicles. Veterans have Krak standard.

CaptainJay. No, they just need to move over 12". It's bike that need to cover 18" I believe.

No, you can do psychic powers just before shooting phase unless they are shooting attacks and if you pass ghosthelm you don't have to roll it again. That would be a pointless Idea of adding it in. In the codex it says, "If a Farseer suffers a Perils of the warp attack his ghosthelm will prevent it on a D6 roll of 3+." Nuff said, nothing like that in the Eratta or FAQ.

By the way:
#12: Mind War allows the receiving model a cover save.

No, you can do psychic powers just before shooting phase unless they are shooting attacks

Psychic powers page of the Eldar codex: "Unless otherwise noted, these powers work as described in the Psychic Powers section of the Warhammer 40,000 rulebook, and are used at the start of the Eldar turn..."

Emphasis mine. The start of the Eldar turn means the start of the Eldar turn, not the start of the Eldar turn but before shooting.

Simply because if you only move 3" that sure as heck isn't 12"

#2 is wrong as stated, it's ignored on a 3+ it's not a save so does not need rerolled
#5 agree to disagree; I won't take him @ 1500 I'll run dual autarch
#8 agree to disagree; he kinda is, even with good ws and a PW that wounds on 2's. Been instagibbed so many times.
#10 Wave Serpents will cry if you don't give them spirit stones; as for Falcons/Fire Prisms I've just been giving the HoloFields to much success
