Wasn't sure where to put this, so decided on here. What are the most common rules mistakes you see, and/or make yourself?

What I always see:

Monsterous Creatures need 25% coverage to get a save while in area terrain(they don't)
Ordinance weapons allocate wounds from the central hole (nope, that's barrage)

My mistakes:

Biovores are BS 4 (thought they were BS 4 for a decent few months... horrible mistake. They're BS 3)

**Jimsolo**

Most common mistakes I see:

People believing that if one model in a unit has cover from the firing unit, then the whole target unit has cover. (Instead of, if one model in the firing unit grants a cover save, then the whole unit will grant a cover save.) This is pretty widespread.

And it isn't actually a rules mistake, but I see people forgetting their grenades all the time. Sometimes I think I'm the only marines player who throws them.

**varl**

you aren't the only one, jim. it surprises the crap out of everyone I throw them at, though

**Desubot**

The majority of assault phase rules.
players at my store completely forget about the entire assault process such as moving 20 inches to get everyone into BTB after initial charger, skirting around terrain or moving through friendly models without enough base space.

Oh and my favorite being people removing there characters during a challenge and putting them way off to the side.

People referring to Ordnance as Ordinance, which is something altogether different... ?

I enjoy chucking 'nades at planes. It makes me giggle,

I see a lot of people forgetting their grenades as well. I know I've sworn a couple of times I've forgotten about having mine.

Forgetting the plethora of standardized equipment your infantry and vehicles come with in a new codex that they didnt used to in the old codex, and which you havent taken as an extra upgrade.

E.g. for me as a BT player, frags and krak nades on all squads now.

Doing a Deny the Witch roll when getting targeted by psychic powers.

Using your guns to target enemy buildings to bring it down.

As a Tau player, photon grenades.

As an Eldar player, plasma grenades and the ability for most of my squads (including Guardians) to be able to chuck them at an enemy (S4 AP4 small blast is nothing to laugh at)

Counter-attack on my Dire Avengers

Searchlights on my Space Marine vehicles

Smokelaunchers on my Dreadnought

ATSKNF not allowing Space Marines to get Sweeping Advanced by enemies.

**Desubot**

"ATSKNF not allowing Space Marines to get Sweeping Advanced by enemies."
People forget this?!

Actually i also tend to forget the chose to fail part of ATSKNF

Edit: VVV You are correct it seems.

**bogalubov**

I frequently forget to cast psychic powers before moving and then have to ask opponent if I can do it out of sequence. The 25% cover for MCs is a holderover from last edition. Although I'm not sure how a tervigon can hide his footsies in a grass patch and claim a cover save while a tank of similar size needs an actual wall to hide.

Isn't that tactics from the last SM codex that allowed you to fail? I don't think you can universally do it anymore.

Cover saves in Ruins

almost 1.5 yrs into 6th and i can't find 2 people who play it the same way.

That one is pretty simple luckily. Most ruins also come on a base, which counts as area terrain. When determining cover, only the best available cover is used. So if one has not gone to ground, then the choice is between 5+ area terrain or 4+ ruins, thus the 4+ is the better cover. When a unit goes to ground, the options are 3+ area terrain (5+ with +2 cover bonus for going to ground in area terrain), or 3+ ruins (4+ with +1 cover bonus for going to ground), thus the best cover save is 3+ (same for area terrain or ruins).

The most common mistake is for people to apply the +2 cover bonus from area terrain on top of the 4+ ruins cover save and they claim a 2+ cover save. I have no idea why this misconception is so frequent, but I do know that people will do the mental equivalent of what a contortionist does when they think they can gain an advantage.

**chelsea_hollywood**

The local misconception is about two models shooting at each on the 2nd floor of a ruin w/ no intervening terrain. do they get a cover save? ;-)

hold over from 5th says they do, the book says they don't. most people have been giving them a 5+ on the "understanding" that each level is area terrain...

**Ferrum_Sanguinis**

People forgetting that all characters, not just ICs, have Precision shots and strikes. At least three times people have called foul on my when my Sgt sniped out a power fist or whatever.

Another one is people forgetting that MCs no longer need to be 50% for a cover save.

All the time. Usually players who are either brand new to the game, or have only ever played xenos armies before.

This is the one that i have never remembered!

**Sir Arun**

I also forget that Melta bombs can be used against Monstrous Creatures

**Mahtamori**

Cover from certain objects don't give standard 5+. Hills and shrines give 4+ for instance. So do wreckage and tank traps.

**Maelstrom808**

People thinking that just being behind an ADL overrides the "25% concealment" requirement for cover.

Sorry that's my 5th showing as well as the wrong rule from 5th (which i also forgot a lot in before 6th C:SM)

**sing your life**

"units can charge after running" seems a common mistake.

**gossipmeng**

My first few games of 6th I forgot Tau drones are initiative 4 - I'm so used to I2 that I thought they were the same.

Also my shas'vre get an extra CC atk (3) - I use it primarily for the +1 leadership

Also my Tau commander has 4 attacks not 3.

I believe that's Marneus leading his boys in blue who can voluntarily fail a passed LD check now.

ATSKNF now gives immunity from Fear.

Ultra pimp let you auto pass LD.

Its from the generic Combat tactic. "a non-fearless spess merine unit with this special rule can chose to automatically fail any morale check it is called upon to take" pg 51 5th c:sm.

**DarthOvious**

The things common down at my store.

1) Grenades, either throwing them or using them in combat

2) Assault Phase pile in 3" moves, they tend to be more like 6" instead half the time. To be fair I think the guys just don't care really. They just want to have some fun.

3) I've seen people move characters when in a challenge and move them to the side. Doesn't bother me. I just go along with what everyone else is playing. As long as its not something illegal that puts me at a massive disadvantage.

**Guitarquero**

I game i forgot that my Nurgle Sorcerer was in Fact Typhus and i got him into close combat where we couldnt kill each other than at about turn 4 im like wait... Thats supposed to be typhus wtf am i doing (Because i took zombies, than realized wait shouldnt i have this guy) Anyways i was already winning the game before realizing it and than wrecked the sqaud of units i was in cc with, my Opponet wasn't too impressed haha.

**zilka86**

People think that cover save are 5+ for everthing. and when you go to ground ur cover save is a2+. I play it as it adds +2 to ur cover

Which is also wrong.

GtG gives a +1 to cover. And will you please use proper English? I know you've been asked before.

One rule I keep seeing come up is that "1 automatically fails". No such rule exists yet people think its true.

**conker249**

There are a few references to a "one always fails". Here is a few I found

pg 13 under roll to hit, "roll of 1 always misses"
pg 14 roll to wound says "a roll of one always fails"
pg 19, under maximum save "a roll of one always fail"

Which are specifics. I've had people claim (and this also came up recently in YMDC), Servo-harness + 3 Servitors (+4 bonus to BotO) still needed a 2+ as a 1 always fails.
