Terrain Rules Explained! Warhammer 40K 10th Edition Core Rules 

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

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.

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

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

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

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

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

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

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

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

thank you so much for this!

This is excellent. Excellent.

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 :)

TY for the Video

Best video on the subject

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?

great video

Thanks for this! I still find cover baffling.

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

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.

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

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?

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

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

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.

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?

Cover rules this edition are ridiculous lol

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.

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?

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

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?

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

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

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?

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?

This Infantry unit is not wholly within the ruins, so can not see out of it normally. Your unit cannot shot to drenought (nobody). Am i wrong? Even unit is wholly in ruins. Drenought doesn't get benefit of cover because every model cannot see him fully.

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?

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!

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.

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

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

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

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

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6MewSMGC9ek.htmlsi=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

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.

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

This sucked
