PFS Question: People Providing Cover


Rules Questions


This is a PFS question as I've always seen it played (and GM) as RAI instead of as RAW.

RAW Facts
1) People provide cover.

2) You can not take a AoO if someone has cover.

3) You can use people to provide cover to do a activity that would normally draw a AoO.

Example: Monster has reach. Tank type is standing in melee range of monster. Caster type is hiding behind Tank type. Caster cast a spell.

Normally the monster would always get its AoO on the caster. As played by RAI and I've always seen.

Problem is by RAW - and I had it pointed out to me in a game that got run. The monster does NOT get it's AoO as the tanking type is providing cover for the caster.

How should it be handled?

(1) Play it like I've always seen it played, monster gets it's AoO (would allow the player to change action)

or -

(2) Play it as RAW and don't allow the monster to get the AoO off.


I would say no AoO. Thats part of what the meatshield's bringing to the party by standing right there. I THINK a huge creature could go around a medium one by attacking in 3-d though.

Whichever way you do it though, let the character make their decision based on how the rules of the universe are operating today. If that means you need to stop the game for a second and ask "are you sure you want to do that? The big giant thing will get to whack you?" then do so. I don't normally consider it a double secret feature of the 20 foot tall monster that its got a bit of reach to it.

In PFS you're going to run into "what he hells?" from people that have been doing it the right way the entire time. Thats one reason its important to do it the right way, especially since there's not much room for ambiguity here.


This argument all falls in the RAW vs the "always seen it played this way" for PFS. As PFS is always supposed to use the RAW.

Most 99% of the people it won't be a problem with. It's just that 1% that always seems to crop up that causes the problem.

Part of the core assumption of PFS is that games are to use the rules as written unless there is a stated exception in the guide to organized play, in the official FAQ or posted on the message boards by Paizo staff.

IMO however this sounds like more of an issue of the people you have been playing with being unaware of the fact that cover prevents AoO's

Actually, I do not think that is RAI - I actually think the RAI would be for the guy between to provide the guy behind cover. This let's heroic figures be, you know, "Heroic", at least IMHO. The big martial hero gets to shield the squishy character from harm. How is this wrong? It's classic! I've seen it on the cover of fantasy novels for years (30 or 40 years at least!)

IMHO - What you have is "a house rule" that is present at the tables you normally play at. Which leads into the second part of your post.

"How should it be handled."...

You have to decide how you want to do this? Play by the rules (what you calling RAW) or play by house rules. Just realize that every time you teach someone the house rule - and we teach this game of ours by example right? - every time you run a PFS table by house rules, you are setting your players up for problems when they go play with someone who runs the game with the Rules As Written. Ultimitly, you are teaching someone that "house rules" are ok... at least at your table.

Now, how would/did I handle somethiing like this? Well....

I could easily say - get a shirt printed with the rule on it.

But (speaking from experience - I have shirts with the Take 10 rule on them that I wear sometimes, and even give away sometimes) you might not want the problems this will bring you...


creatures provide soft cover, which does not prevent attacks of opportunity. this used to be worded more concretely in the rules, but it looks like the wording may have been updated in a more recent printing of the CRB.

however, even the current wording points out that soft cover only applies against ranged attacks (emphasis mine):

Core Rulebook wrote:
Soft Cover: Creatures, even your enemies, can provide you with cover against ranged attacks, giving you a +4 bonus to AC. However, such soft cover provides no bonus on Reflex saves, nor does soft cover allow you to make a Stealth check.

That's pretty much how it works. Here is your argument:

Soft Cover wrote:
Creatures, even your enemies, can provide you with cover against ranged attacks.
Cover wrote:
When making a melee attack against a target that isn't adjacent to you (such as with a reach weapon), use the rules for determining cover from ranged attacks.
Cover and Attacks of Opportunity wrote:
You can't execute an attack of opportunity against an opponent with cover relative to you.

If they push the question you simply respond by politely asking for them to come up with a rules justification as to why not using some kind of citation. "I don't like it that way," is not a PFS acceptable answer. If pushed accept it and report them to your local representative. As you can see even a venture captain can get it wrong. ^

I don't think so. A creature with reach has to use ranged attacks for determining cover. That means no matter which square the huge creature chooses to attack from, the creature has to be able to target every corner of the target without crossing the lines of square that provides cover. I'd have to double check a map, but I don't think that's possible regardless of the creature's size.

actually, I think his question is not how does he get them to run it by RAW, but it looks like the OP is asking:

does he run it by what he thinks the RAW are?
or
does he run it the way everyone else he plays with does it, even if it isn't RAW?

So reach or ranged it doesn't matter, if the meatshield is in the way he grants cover.

And Differences like this are why i feel obligated to point out when a player is going to draw that AOO if they do something standing there.

Sovereign Court

Good point nosig! Missed that entirely.

Totally run it Rules as Written. Really just run like everything that way in a living campaign. It's the only fair way to do things. We've already abandoned like 3 outlets for just horrible house rules creeping into PFS games over the years. Yuck.

It goes both ways after all, how else are you supposed to protect squishy caster bad guys from Enlarged or other reach having PCs? Not really sure that it's RAI not to be that way?


As the Large creature can calculate cover from any square it occupies, why not draw the line from its UPPER squares to the top of the target square? Its 3d :)

Basically what he said. Crappy ASCII art to follow:

__XX
CMXX

C=caster
M=meat shield
X=large monster

Monster can attack from the top left corner with no cover therefore there is no cover and an AoO is possible.

I disagree. If the monster draws a line from his top left corner, it has to hit all 4 corners of C or it has cover per rules for ranged attack cover. A line from top left to bottom right of C's Corner will go through M, thus it has cover.

If we're going 3D then you have to draw it to the ground corners of the cube too.


How about this then -

A person moves through a threatened square but that person has a ally in that threatened square.

Hmmm.. without breaking out the leggo blocks and pipe cleaners does that ever work against an adjacent target?

That one's easy.

CRB, page 193 wrote:
You can move through a square occupied by a friendly character, unless you are charging. When you move through a square occupied by a friendly character, that character doesn't provide you with cover (see page 195).


Yep, that one is easy, I'll also put in that you would be squeezing, thus in addition to not having cover and provoking the AOO, you would get a -4 to AC.

Uh, you're not squeezing when moving through an allied square.


Friend: You can move through a square occupied by a friendly character, unless you are charging. When you move through a square occupied by a friendly character, that character doesn't provide you with cover.


In the prd for squeezing it says
"A creature can squeeze past a creature while moving but it can't end its movement in an occupied square."

That's saying that you can move through creatures while squeezing, not that moving through creatures makes you squeeze.


I see I read that wrong, good to know

ranged attack cover is calculated differently than melee - ranged attack chooses 1 corner and looks lines to all corners of target - it is very possible for a large or huge creature to choose a corner that bypasses the medium creature entirely.

Melee attack cover is calculated in an opposite fashion.

If two melee combatants are around a hard corner of each other, they have cover for their melee attacks. But if an archer (or reach attacker) is around a hard corner from the melee the archer (or reacher) does not have cover for a ranged attack.

You can choose "a" corner, but in order to avoid Cover, you must be able to hit ALL corners without passing through the square of something that provides cover. That is the definition of cover. Look at Sammy T's diagrams. Notice how he's drawing lines to four corners of the target?

We're talking about this situation

C= Creature, P = Paladin, W = Wizard, X = empty squares

C X X
C X X
C X X
C P W

There is no line from anywhere that C stands that can target all four corners of W's square without passing through P's square. The Paladin provides Cover (soft) and thus the Wizard is protected from AoO's. You can extend C's square out 1000 times and the Wizard's southwest corner from the top will always get cover.

I'm curious why the OP thinks that the rules are intended to be different than what's actually written.

"Surely the rules that I am playing are the rules as they were Intended to be played, otherwise I would be playing them wrong... and that can never happen. Are you trying to say I am doing it WRONG?! I'm the DM!"

Sczarni

"Rules-As-Intended" is a double edged sword, and should be handled with extreme care.

On the one end, "intension" often relies on "interpretation". An author's intension may be ambiguous, and multiple interpretations may arise because of that ambiguity. These different sides may all run a rule differently, with each of them claiming that "RAI" is on their side.

On the other end, sometimes an author's intension becomes void, as in the classic example of the Titan Mauler. The class was intended to eventually wield gigantic weapons, but the Design Team changed how the class worked because it would become too powerful if left "as intended".

Somewhere in the middle of these two is the best place to exist with regards to "Rules-As-Intended".

It happens occasionally. (throwing shields)

I just don't see why this is one of those times.
