Is Bane Outsider (Extraplanar) a legitimate type?

[Dameragon]

I want to add Bane Outsider (Extraplanar) to my weapon but some Society players think this is not legitimate since in the Bestiary on page 317 Extraplanar is not listed under the Outsider section of 'Monsters by Type).

In this thread however: http://paizo.com/forums/dmtz4z9u?Does-a-Bane-weapon-work-on-outer-planes#13

people seem to think its legitimate.

Does anybody have thoughts on this?

It's not legitimate. Think of how many outsiders it covers and how much of the time, and it fails the smell test.

Otherwise, it's pretty simple: the subtype needs to either appear in the official list in the Core Rulebook, or it needs to be a self-evident new type of outsider (asura, div, and so on).

Let me play devils's advocate here.

1) Extraplanar is an official sub-type as listed in the Bestiary p312 under the section: "Creature Subtypes"
2) If you look at a creature such as Air Elemental in the Bestiary (p. 120) Extraplanar is listed as one of its subtypes.
3) This ability would not function on the Astral Plane, the Ethereal Plane, or the Plane of Shadow or when you are on a creatures native plane.

By the above, Extraplanar IS an official subtype and one that has limitations.

The biggest evidence for me is that the one place such a subtype would be most likely to be listed (Ranger favored enemies), it is absent. This isn't like divs or oni, which simply didn't exist yet. It was purposefully excluded. This makes sense, since the type pretty much just exists to say "can be targeted by "Banish" and such."

Saying that it doesn't work on transitive planes is a pretty big stretch for a "limitation." Unless the campaign took place primarily in such places, it just isn't going to matter. Meanwhile, you have found a way to create what amount to a weapon of Bane Outsider (All). Even if it is technically legal, I doubt you will be able to convince others given the overpowered nature of such a weapon.

The list I'm thinking of is apparently under ranger. That's the list of legitimate outsider subtypes in the base rules. That list gets extended slightly by new types of outsiders in later book. Extraplanar isn't on that list.

Checking the other "weird" types (chaotic, evil, good, law, air, earth, fire, water), all of them mention they usually apply to outsiders. Extraplanar does not. Extraplanar's a global modifier for any creature, as opposed to a subset of outsiders.

Basically, you're talking a bane that'd work almost 100% of the time on outsiders, since very few adventures take place outside the Prime. Again, this obviously fails the smell test.

Extraplanar Subtype: This subtype is applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. Monster entries assume that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have it when on its home plane). Every extraplanar creature in this book has a home plane mentioned in its description. Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a transitive plane, such as the Astral Plane, the Ethereal Plane, or the Plane of Shadow.

Still I think this is one of those cases that some one could make a case for a Bane Outsiders (Extraplaner) weapon, but it violates the sprite of the rules if not RAW.
