[@BoostaG]

Would love more core rule videos. Having only played in 10th I constantly encounter people bringing in their 9th rules and confusing the heck out of me

[@capt.cheesecake6875]

So a great video man, in my LGS we play very casual, but after this video I believe most of the time we are applying the rules incorrectly, mostly who gets cover and who doesn't, which rarely makes a difference, but if someone, like myself, wanted to get to tournament level, all of this is very important.

[@michaelwinborn7701]

You explain things so thoroughly in a way to understand, I started watching custodes content but would watch more vids like this!

[@johnnyv4354]

Thank you! This helped me understand cover correctly and the tournament style ruin rules so much better.

[@trevorlanthier5385]

You should be the official rule explainer for GW, that’s the first time it’s all made sense

[@HaevyGlow]

As someone who just bought his first army (obviously Custodes) and never played 40K before, this is very helpful

[@Hokum80]

Expertly explained, thanks! Always good to get a refresher.

[@Slerex]

Ty So much, we had a huge discussion about this recently

[@lolmattbill]

Nice video Rejnols, would love to see a video similar to this with pile ins and consolidations because you explained this one really well and would love to understand those two moves as it will help my games getting on objective markers or making shorter charges in future

[@samuelconder3463]

Thank you so much for this video, best explanation out there, ima watch it on repeat in the background while i game.

[@colinwalker6804]

Thank you for this video, I found it extremely useful and informative.

[@patrickneu7481]

thanks for your explanation :) there might be some situations where you NEED to be partially within ruins. even though you don't benefit from anything; e.g. when you desperately need to hold an objective marker :)

[@questery]

Holy shit, is that really how it works? That's stupid lol. Great vid man, thanks

[@KyleDLH]

I might be being dense here, as I might be misunderstanding the point of your example, but the example you gave at 12:06 Wouldn't the Custodes get benefit of cover from being inside the ruins whilst the enemy unit is not? Wouldn't the Custodes in the ruins be able to see all the Infiltrators? I thought if a unit is within a ruin, given nothing is blocking line of site, they could see the enemy models and vice versa?

[@Rejnols]

There is a difference between having Line of sight and having full line of sight. Yes they would get cover if the model is wholly within the terrain feature

[@TheHockeyFanClub]

Dont like the part around 22mins where you had the custode tank partially on the ruin base, the dreadnaught can shoot it, but it couldnt shoot back. If the tank is partially on the ruin, it should still be able to shoot back if it can get shot at. LoS should always go both ways, the rail gun on my broadside sticks a good 2" off the base, I could abuse that like crazy.

[@JaviTeijido]

Perfect explained. U got my sub and my like. Congs!!

[@jakubmizerski5685]

Best video on the subject

[@Dewoy1]

I just came from a game in my local club, and just had an arguement about visability from units inside a ruin. He said my unit (wholly within) a ruin could should out, due to not having holes or windows. And then a second guy came along and they kinda ganged up on me, saying that my understanding of the rule was false. But if i gathered that right here, then i m technically correct, but ppl tent to play the bottom floor closed yeah?

[@Rejnols]

Generally most tournaments play with bottom floor being closed yes. However always ask or read the player pack to make sure

[@Ed-om9xy]

This is excellent. Excellent.

[@cientoydos]

Hi, we always use wtc terrain and today we discussed a lot about wether the floor windows are closed or not, the big ruins you can buy are always closed optically, and the small ruins in the wtc rules i got are especially marked as closed with the red x. So is it all closed or not, would really make a difference i think... thank you!

[@Rejnols]

Its been a while since i played so they may have changed it. When i played all large ruins where fully closed at all levels, and small ruins where closed at the ground floor, but some variations had an upper level with windows or cracks in the wall that was played as being open.

[@petemalysewich6845]

Out of curiosity, why do tournaments (mainly using WTC rules) treat the ground floor as blocking line of site for units within them? ie can’t shoot in, can’t shoot out. At least from the front and one side where the walls are. Kinda defeats the purpose of the GW rule on benefits of cover, no? Gives an advantage for quick melee units jumping from ruin to ruin Are they looking to encourage people to flank units in buildings and/or get people to throw long range fire/vehicle units in strategic reserve, use rapid ingress and get them in behind?

[@vvabberjockey577]

Cover rules this edition are ridiculous lol

[@Fhastor]

thank you so much for this!

[@SilverDragonAcademy]

Thanks for this! I still find cover baffling.

[@grumpycup4762]

WAit, at 8:17 ish you said something about saves? Your opponent decides how they allocate the saves? Please elaborate. 40k is in essence a Model vs Model game. The fact that we, in regular play, tend to do it was "unit vs unit" is an abstraction. If i CHOOSE to target your model outside of cover with a shooting attack, you cannot use the cover-save for that... Right? Or is there something in the cover rules that says that you can?

[@Rejnols]

Let me try and answer it quickly! Your Unit (A) contains = 5 models. Opponent Unit (B) contains = 5 models. Unit A has 4 models that can see 1 model from Unit B. Because the 4 other models from Unit B are not fully visible, they get the benefit of cover. Your opponent can freely choose to take the wounds from Unit A on ANY of the models from Unit B even if they are not visible to Unit A. Hope that makes sense!

[@TheReaperOfTheLost]

great video

[@Akket85]

TY for the Video

[@alexrowson-brown6568]

It’s 3+ max only to ap0 weapons Custodies still get 2+ save vs ap1 if you have cover

[@Rejnols]

I did say that as well!

[@GeoffChapman-w4z]

So if the tournament is using the ruins as solid walls you would not be able to move into the building with the vehicle. Is that correct? If however you were using the terrain as it is made, wiziwig and the wall part of the ruin was only 2 inches, the vehicle could move in and then through it as 2 inches does not impede movement. Is that correct? Sorry to ask.

[@cyberjonesy]

This is why casual players don't come back to the store XD

[@Grumium101]

21:16 Can each unit shoot the other with all their models?

[@wmkim4039]

Point of the video…if you aren’t playing in a tournament…better to home brew your own terrain rules 😂

[@SgtOddballz]

agree, these rules are dumb

[@alexrowson-brown6568]

If he takes it on the exposed guy he has to slow troll saves till the one guy is dead then can fast roll the rest

[@Rejnols]

Of course that is what i was trying to say :)

[@MagicE13]

I really hope that the Amazons Horus Heresy With Henry Cavil is 'this' true to the lore.🤯

[@Connor-uj7se]

Stupid question then is all ground floors are closed what determines if the ruin has a second floor? Is that WYSIWYG? If not how would you model it?

[@Rejnols]

Wtc mostly have a second floor, and most other tournaments have it as well. I'd imagine most people play it wysiwyg

[@VibratingSky]

My terrain footprint is usually L shaped, but even if I treated it like a square, then I couldn't fit a Redemptor Dreadnaught into it wholly. Does this mean any infantry within ruins are safe, and need to be flushed out some other way?

[@Rejnols]

You are getting it wrong. If something is within terrain, it can be seen, so you don't need your redemptor inside the same piece of terrain to be able to shoot at them. Just need true line of sight if they are within the terrain piece.

[@georgesd2167]

My understanding is that if one model in your unit cannot see any of the enemy models they all benefit from cover. However if you shoot at that enemy unit does your model that can not see any enemy models get its attacks included in your total attacks in the unit?

[@Rejnols]

That is correct, as i explained in the video.

[@jacobwilliams2246]

Great explanatory video. But I kind of hate how the rules shake out in the example of the custodians shooting at the dreadnought. Clear view for 4/5 guys but since 1 is behind the wall, they’re all benefit of cover shots?!?!? Wack. Would like 4 clear shots and one shot with cover. I guess that kind of nit pickiness can slow down the game.

[@ВиталийНовиков-ъ2х]

The point is that the rules of benefit of cover refer to being hidden by terrain from "every" model in the unit, not "any". "If that model is not fully visible to every model in the attacking unit because of this terrain feature, that model has the Benefit of Cover". So in this situation we should check if EVERY Custodian MODEL cannot fully see the Dreadnought because of the terrain. Four of them can fully see it, so the condition for getting the benefit of cover is not satisfied. Getting benefit of cover this way is wrong, beacause rules for benefit of cover do not refer to not being fully visible to a UNIT (such a term exists in the FAQ though), but to EVERY MODEL IN THE UNIT. That is a big difference.

[@ThatAmnesiaGuy]

If a model wholly within a terrain feature shoots at another model wholly within the same terrain feature, and can fully see that model, does it still get cover?

[@Rejnols]

Yes

[@Malachiasz1983]

5:50 - this is one of the most convoluted and misleading attempts to explain benefit of cover. Nowhere does it say that benefit of cover can "improve your save to a maximum of 3+" or "reduce AP". Nowhere does it specify the order in which modifiers should be applier or tested because this order is not needed at any point. It says: "Each time a ranged attack is allocated to a model that has the Benefit of Cover, add 1 to the saving throw made for that attack (excluding invulnerable saving throws). Models with a Save characteristic of 3+ or better cannot have the Benefit of Cover against attacks with an Armour Penetration characteristic of 0." In other words benefit of cover applies if even one of the below criteria is met (no other logical test are required): A) If you are being shot at with a weapon with AP < 0 B) if you have save characteristics of 4+ or worse

[@Rejnols]

The ordering is what matters. You apply the bonus from cover AFTER applying AP. Apologies if i didn't make that clear, but it is how it works.

[@ValentinBaca]

Benefit of Cover: Add 1 to armour saving throws against ranged attacks. Does not apply to models with a Save of 3+ or better against attacks with an AP of 0. That’s it. That’s literally the rule. Didn’t need the whole “ordering” explanation which isn’t even correct

[@ValentinBaca]

@@Rejnols Benefit of Cover: Add 1 to armour saving throws against ranged attacks. Does not apply to models with a Save of 3+ or better against attacks with an AP of 0. It has nothing to do with “ordering”

[@Oldblueeyessc]

If something has a save of 2+ against something with AP0 will that unit still get 2+ or will it go up to a 3+ save?

[@AaronRoss-rr8qt]

Remains 2+

[@michaelcaley1359]

I feel like it would be much easier if enemies out of cover had to be allocated wounds first....

[@hedale9078]

could someone give me a link to these rules i mean pdf from warhammer?

[@DoubleWing1992]

So imperial knight cant "toe in" to a ruin to be able to shoot through it? Cause unless the "footprint" is a massive a imperial knight well never be able to get base "wholely within". Seems like knights just dont fit into the game now. Boards are so Terrian heavy they can barely move and cant see anything to shoot. Unless i am missing something. I know super heavy walker helps but idk.

[@Rejnols]

I believe they can due to the titanic rule, but i don't play Knights or against them very often so i am a bit unsure on the ruling there.

[@theblackantonio]

You forgot the exceptions to towering and aircraft. No one cares about aircraft but rules for LoS for towering units gonna be important

[@Rejnols]

Totally fair, i have yet to play with or against it this edition so its not something i think about. I believe the most recent FAQ changed it so titanic no longer ignore all footprints, but only footprints and ruins where they are partially within.

[@gravelizard]

where i can find those rules for towering@@Rejnols

[@mkminiaturesstudio6106]

Would a model that is wholly within a ruin base always get cover? Or only if it’s not fully visible. Here’s what it says in the rule book: BENEFIT OF COVER Each time a ranged attack is allocated to a model, if that model is either wholly within this terrain feature, or it is not fully visible to every model in the attacking unit because of this terrain feature, that model has the Benefit of Cover against that attack. Also let’s says you have a model that can stick its gun past the footprint of the ruin but isn’t wholly within the footprint, can it still shoot by tracing los from the gun? Thanks!

[@Rejnols]

Yes i somehow missed to explain that part, wholly within will always grant you the benefit of cover. You would be able to shoot and be shot at, as you are wholly within the ruin, and los is not from base to base but from ANY part of the model to ANY part of the other model.

[@mkminiaturesstudio6106]

@@Rejnols los is from any one part or do you have to see from all parts of the shooting model. It’s very confusing since it can seem like if you are shooting out of the cover you are in, then your opponent will always get cover?

[@Rejnols]

@@mkminiaturesstudio6106 I'm a bit confused about what you ask? If you from that one point cannot draw full Los to the entire model you're trying to shot they will get cover.

[@mkminiaturesstudio6106]

@@Rejnols sorry for the confusion. Let’s say my model is fully within a ruin and is behind one of those small 2” wall sections that has some small gaps. Will that little wall I’m behind give my opponent cover? Or can I shoot through it with full visibility?

[@Rejnols]

@@mkminiaturesstudio6106 Again that depends if the point you measure from can see the entirety of the opponents model or just part of it

[@doctorharlingston]

AAAH A STEP OF CONCRETE I CANT SEEEEEEE! I wish it were more realistic

[@SumsieBun]

I‘m sorry but being able to shoot the tippy top of a models flag will always sound so stupid to me. If you can‘t see the base i dont think you should be able to shoot the unit. Shooting one guys toe with 20 bullets won‘t kill 3 guys, it will only hit that guys toe

[@advancetomayfair]

cover needs to be simplified for the next edition, they are so terribly written in the rules and have been for the last few editions.

[@seomanmax6814]

You fully wrong. Model Fully Visible If every part of another model that is facing the observing model can be seen from any part of the observing model, then that other model is said to be fully visible to the observing model, i.e. the observing model has line of sight to all parts of the other model that are facing it, without any other models or terrain features blocking visibility to any of those parts. I can look from ANY PART of observing model.. - for example from hand of closest model. And from this hand i see full unit - then this unit is FUlly visible.

[@wesc6755]

I really don't like it when rules say things that essentially reduce to "Make a house rule". We don't need a rule book to tell us to create house rules. I wish GW would someday just define canonical rules for terrain and LOS and leave out the fuzzy language. We will "Roll a D6 with your opponent" when we decide to. Why is that in the rules? Lazy design.

[@mastershake42019]

The doesnt help models with 3+ saves is tied to ap 0 weapons. 2 mins in and you got a rule wrong. Ima find another video

[@xaghunjinza8803]

kzbin.info/www/bejne/bH7IqIaDfKhsm80si=4QH9C-AcYebGZJ7G In future pls dont say they dont get cover, new ppl might overloook first part of the benefit which is wholy within terrain

[@huiyou4828]

was confused as well... They won't get cover because of LOS, but they will get it anyways because they are wholly within the terrain, right?

[@phalanxlavasar4729]

This sucked
