Does a Scatter weapon attack all creatures in its cone when making an AoO?

[Ssyvan]

I just want to make sure I have this right, as one of my player's asked about it recently.

This can be achieved a bunch of different ways, but for now lets assume a loaded Blunderbuss on a character that has Snapshot.

I think you only make an AoO against the creature that provokes, but I'd like to make sure.

Here are the relevant bits, I'll bold what led me to that conclusion.

Scatter wrote:

Scatter Weapon Quality: A weapon with the scatter weapon quality can shoot two different types of ammunition. It can fire normal bullets that target one creature, or it can make a scattering shot, attacking all creatures within a cone. Cannons with the scatter weapon quality only fire grapeshot, unless their descriptions state otherwise. When a scatter weapon attacks all creatures within a cone, it makes a separate attack roll against each creature within the cone. Each attack roll takes a –2 penalty, and its attack damage cannot be modified by precision damage or damage-increasing feats such as Vital Strike. Effects that grant concealment, such as fog or smoke, or the blur, invisibility, or mirror image spells, do not foil a scatter attack. If any of the attack rolls threaten a critical, confirm the critical for that attack roll alone. A firearm that makes a scatter shot misfires only if all of the attack rolls made misfire. If a scatter weapon explodes on a misfire, it deals triple its damage to all creatures within the misfire radius.

Attack of Opportunity wrote:

Making an Attack of Opportunity: An attack of opportunity is a single melee attack, and most characters can only make one per round. You don't have to make an attack of opportunity if you don't want to. You make your attack of opportunity at your normal attack bonus, even if you've already attacked in the round.

And Snapshot only changes melee in that bolded section to allow ranged attacks as well.

Since Scatter makes a separate attack roll against everyone, and attacks of opportunity only allow a single attack, it stands reason you only attack the person who provoked.

Thoughts?

The attack of opportunity allows for an attack on the provoker, the cone effect allows for collateral damage. I'd allow only one attack roll and then apply the -2 penalty against the collateral damage targets to see if they take damage by being in the AOE.

I'd apply the -2 to the provoker as well, since it never says the penalty doesn't apply. But yes, I'd allow the aoe to hit all targets. It's a powerful move but you also have to remember allies will sometimes make this a problem for you as much as a benefit, and any GM who uses tactics will have an int 12 or higher enemy try to use your teammates as shields.
