The subject’s creature type and subtype (if any) change to match the new form...
...It also gains all extraordinary special attacks possessed by the form but does not gain the extraordinary special qualities possessed by the new form or any supernatural or spell-like abilities.
Simple question, really. Even though I likely won't go strict RAW on this, I would like to know what the RAW answer is.
I have always considered Polymorph spell to not grant *any* qualities of the assumed form, but it does mention that you take on the type and subtype, which inherently are PACKED with special qualities. So...which statement wins out in the end? Do you get Ex special qualities of the type(s) you assume, or just any Ex special attacks from it?
I'm also curious because I always hated that (in my view, before realizing this type/subtype thing) Polymorph Any Object, a much higher level spell where it's expected if you turn someone to a sheet of paper you can set the sheet on fire and it will burn up just like paper that...you also don't gain Ex qualities, since it defers to Polymorph's rules in that regard. Doesn't make sense for PAO, but on the other hand gaining type qualities is overpowered for regular polymorph, IMO.
I will probably houserule it as such, if I even allow PAO at all, but please can someone tell me the RAW answer here? And please don't start a debate about whether either spell is overpowered and so forth, there's enough threads on that already.
The reason I'm asking, if you're curious is below. Slight spoilers for War of the Burning Sky campaign setting, MY PLAYERS STAY OUT, etc...
To overcome the campaign's namesake effect and survive long-distance teleporting without burning to a crisp at the party's level (too low for Energy Immunity even if I hadn't banned it...which I did), the campaign says an NPC wizard can Polymorph some in the party into red dragons (fire subtype) to get fire immunity. That...just didn't sound right to me. And besides, the campaign offers plenty of other actual legit measures (protection from energy + energy resistance, for example) that it doesn't even seem necessary to broach the question.
