Snap Shot around a corner


Rules Questions

Does the Snap Shot feat allow an attack of opportunity when the target that is provoking is around a hard corner?

O W W
A W W
O T

O = Open space; W = Wall; A = Attacker; T = Target

Thanks!


if you can draw LOS to the square using normal LOS rules, then yes.


No. It's easy to miss, since it isn't mentioned in the Attack of Opportunity section. You have to look at Cover.

Melee cover and Ranged cover are determined differently:

Source PRPG Core Rulebook pg. 195

To determine whether your target has cover from your ranged attack, choose a corner of your square. If any line from this corner to any corner of the target’s square passes through a square or border that blocks line of effect or provides cover, or through a square occupied by a creature, the target has cover (+4 to AC).

When making a melee attack against an adjacent target, your target has cover if any line from any corner of your square to the target’s square goes through a wall (including a low wall). 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.

Either of the 'bottom' corners of square 'A' has unobstructed lines to all four corners of square 'T' so 'T' does not have cover against ranged attacks from 'A', but 'A' does have cover against any melee attacks from 'T' (since the right-most corners do not have unobstructed lines to all corners of square 'A').

With ranged attacks, from where "A" is on the map, "T" is a legal target and does not have cover from "A". If "T" were further down the hallway they would still not have cover from "A" unless something else was in the way.

As Taja said, when it comes to being up against corners, cover from ranged attacks compared to cover from melee attacks are different from each other.


in this case I would give the target cover from ranged attacks of the attacker.
You can't see it in the op example, since it's using the text base picture, but if you use a grid map you can see that to get to the right top corner of the target (the one in the corner of the two 'W' spaces) the attacker must go through the wall's coroners and border.
Using the text to make a picture leave a gap but the target should be seen as touching the walls and that corner is thus covered by them from the attacker's corners (since the attacker's space and the wall's space stop at the same line, his corner will go through the wall's corner).

As zza ni pointed out, the line to the bottom left corner of the target square is blocked as it " passes through a square or border that blocks line of effect or provides cover".


top-right, the lower left is targetable from the attacker lower left corner.
(or did you mean the attacker lower left goes through the wall to get to the target's top right?) we're dealing with ranged cover so the best corner the attacker can pick to attack from is his lower left.

anyway, in this case they BOTH have ranged AND melee cover from each other. both have a top right corner which has cover from all the other's coroners, neither can reach said corner of the other without going through the wall's border and corner.

The core rulebook has an example scenario that is similar to this case (with some differences), Merisiel didn't receive cover when the ogre attack her from the corner
(though until today I still not fully understand how it works)


it seem like that for melee with reach they took PART of the words from the ranged cover. they let him decide which corner to check from like the ranged cover rules, but they kept his melee rule of only needing to reach the targets square, and not all of it's corners. ("to the target’s square" in melee as opposed to "to any corner of the target’s square" in ranged)

the ogere's top left corner can reach the two facing corners of the rouge to his left and as such she doesn't get cover from his melee+reach attack.

Cover in melee has the penalty of having to use all your corners, but the benefit of only aiming at the part of space closer to him without need to reach all the far away corners. melee with reach can pick his attacking corner AND only need to reach the facing corners. Cover in ranged can pick his attacking corner but must be able to target all the enemy's corners (or all the corners of 5 ft of him if larger)

The ogre is using a melee attach with reach.

The LOS e LOE runs along a blocked border. It there is a wall on the border, the border is blocked.

Yes, you can choose any corner of your square to draw your line of attack from (as opposed to a melee attack, where each corner is checked to the target's square). You still draw that line to each corner of your target's square. When it says 'any corner' it means from your chosen corner to any corner, not that you choose both corners.

Since a line from any corner of the attacker's square (in OP's diagram) will pass through a solid object or along a border that would, the Target has cover (and does not provoke AoO). Specifically, even choosing the lower left or right corner for A, a line would still pass along a solid border of a square to the upper right of T.

A very helpful diagram. While I cannot say with absolute authority, I think the issue is that they mistakenly used reach (which the ogre does have) but didn't go into the details that despite having reach, the ogre is not making a melee reach attack. Merisiel (#2) is still adjacent.

Note that while it says a reach weapon (and the ogre does have reach) it is not a reach attack, since Merisiel is adjacent and the ogre, despite having reach, can still attack adjacent foes, meaning this melee attack is not counted as a ranged attack for cover purposes.

So why doesn't she have cover, since a melee check would be from any corner of the ogre's space to her square? And clearly some of those would pass through a wall?

Quote:

Combat > Big Creatures and Cover]

Any creature with a space larger than 5 feet (1 square) determines cover against melee attacks slightly differently than smaller creatures do. Such a creature can choose any square that it occupies to determine if an opponent has cover against its melee attacks. Similarly, when making a melee attack against such a creature, you can pick any of the squares it occupies to determine if it has cover against you.

So that means the ogre (being bigger than Medium) can choose the most beneficial corner (in this case, the upper left, as shown in the image and diagram), and since it's a melee attack against an adjacent target (Mariseil) and not a reach attack, it doesn't use the Ranged method for determining cover (just to the square rather than every corner).

It is rather arcane and byzantine, but that seems to be the manner and method I am determining. (Though it's still entirely possible they just made some mistake as well).

I agree that the target (in the OP situation) has cover from the attacker with Snap Shot. Only replying to point out, for consistency, and because this might be easier to see than in my previous post where it might have gotten lost...

The ogre does have reach, and even saying that it is using reach to reach Mariseil's square, she is still considered an adjacent target to the ogre, and the ruling for determining Ranged cover is used for targets that aren't adjacent to the attacker. Not whether they're adjacent to the corner it's checked from.

So fighting in a 5' wide corridor gives cover to everyone???

I have to read this as 'through' a border not being the same as 'along' a border.

A 5 foot corridor is going to restrict some weapon swings and make fighting harder.

And given that PF is a game, not a simulation, there are always going to be a few weird cases with RAW

no. not unless you are in the same space as the wall. I mentioned above that :

"since the attacker's space and the wall's space stop at the same line, his corner will go through the wall's corner"
you are not in the same lane as the walls in a 5 ft corridor, they do not block you. but in the case above your space end in the same lane as the wall, you attack FROM inside your space (the corner of it) and as such you must o through the inside part of the all to reach the far corner of the target. (I made the picture so it would be easy to tell, did you bother looking?)

Technically, for ranged attacks, yes.

Not for melee.

Most GM would rule that there is no cover if the attacker and the target are in the same, straight corridor.

But that isn't the situation in the OP post. The attacker and the target are in 2 different corridors at 90° of each other. In RL people moving along two narrow corridors like those will see each other at the last moment.

I think Taja the Barbarian was referring to a ranged attack enfilade of a target in a corridor. With A attacking T, as opposed to B from the side.

The issue is that even if you move the attacker one square down, he still is likely to use the exact same corner to determine cover (bottom right corner from his current position, or top right corner in his new position) so the answer to 'does the target have cover?' should be the same.

I'm reading the 'through a border' rule to cover situations were something blocks the border but not the actual neighboring square (like a thin interior partition wall, maybe a curtain, an open door, or any one of the solid 'wall' family of spells) which otherwise would not technically grant cover. This just makes more sense to me than a reading that needs to be ignored periodically for the game to make sense...

It looks like this particular item has been long debated on these forums:
https://paizo.com/cgi-bin/WebObjects/Store.woa/wa/search?page=1&what=&a mp;forum=v5748dmtyzkl3&thread=&person=&includeUnrated=false& ;includeUnavailable=false&sort=1&q=%22through+a+border%22%2B%22cove r%22&forum=v5748dmtyzkl3&sort=0


no, if you lower him one space down he can use any of his corners from which a straight line to any of the target's corners will not pass through any wall but hit the target corner BEFORE it reach the wall. (he attack from and to a space before ether wall start so his line doesn't cross it)

same for melee. all his corners only need to reach the corners of the target that are facing him (not the ones behind. remember melee goes by "to the target’s square" in melee as opposed to "to any corner of the target’s square" in ranged) still no wall in the way.

-

it's easier to think of if you look at each space border as thicker inwards, with attacks lined from his border's corner. since every one attack from inside his space's reach, not outside it. and if there is a wall in the same lane that wall exist to the full range of it's spaces, but the wall does not extend to the space beyond it.

like this image:
pink and yellow can't reach each other's top right corner without going through a wall border.
But green and yellow can to each other.
-with pink actually functioning the same as the wall here, as people -other then one self, can give cover to each other. but as pink's (and the wall's) space end before the next space down starts, he doesn't provide cover in the case of green to yellow.


Added lines to zza ni's pic so that both lines go along border, but pink is on the wall side of the purple line (so cover), but green is on the corridor side of the blue line (so no cover).

Hopefully, that makes more sense.

Yeah. Out of practice and getting mixed up between melee & ranged.

For ranged, ceiling height is probably more of an issue (well, for bows anyway), but that's getting a bit too involved as well
