Polymorph Any Object and Multimorph

Does anybody have any idea what would happen if a wizard with multimorph cast PAO on himself? Seems to me that they would basically have a permanent pick and choose greater polymorph, but PAO is such a bundle of confusion that I'm not really sure about anything. Ideas?

The duration might be changed by a shift in form, so I don't know if it would be permanent.

Not entirely sure, though. ^_^

I guess if you change into something with a duration modifier of less than 9 then it wouldn't be permanent anymore, but then again you can just turn again into something with a modifier of 9+, so i guess it'll be permanent again?

I'm surprised there isn't more interest in this question,considiring a 10 th level wizard with 3000gp can get a permanent changeable greater polymorph by succeeding a caster level check of 15. It seems pretty gamebreaking to me.

Assuming A) there is such a scroll available and B) you make your caster level check (0% chance of failure for an 8th+ level wizard or 55%+ for a 5th level [earliest you can get multimorph]).

Kalind's point remains pertinent, Polymorph Any Object is very good if you're taking something of value and degrading it (i.e. manticore -> shrew for stealth/trap purposes). Attempted as an exploit you'd be going the other way, so it'd be very hard to get 9+. If you had an example of how a human wizard could become god by permanently turning himself into a small monkey this thread would likely explode.

EDIT: Maybe if you turned yourself into a chipmunk? +6 dex, Diminutive AC and good (for level 5) attack bonus/stealth and fly bonus. So an Arcane Archer would be.. Well weak (that -4 str penalty) but comparatively effective. I think this is probably a better level 8 exploit for a mouser swashbuckler with a wizard friend.

More to the point of your thread: I recall a dev post about not being able to expend rounds/minutes of duration for sufficiently long spells -- forget what it was in response to, and as I don't have a link never mind...

Well, first of all you have a constant reshape-able alter self, which is no laughing matter. Secondly, sure, you can turn into a monkey, or a mouse, or a bat, or any mammal, magical or not, (that you can turn to with beast shape 4) as many times as you want as a standard action. It's better than wildshaping until a pretty high level (animal +5, mammal +2, lower intelligence +2). This is just the obvious stuff. It's definitely powerful.
I don't recall such a post, but it would pretty much address the point. Then again, since the spell has other durations, maybe this ruling doesn't apply.

Well it's a 'permanent' alter self for most humanoid subtypes, but it's not permanent for much else. So again without a specific broken exploit it's not going to generate much attention. At 3k it's better than a Hat of Disguise, greater (more limited duration wise, better versatility). Wildshape gives you a wider variety of options you can transform into for hours at a time, whereas PaA is more limited in its long duration options but grants faster access to high level transformations (which would not be permanent).

Again, any magical mammal is up for grabs, and many other things that are more specific. Any animal the same size as a human, for example, or a giant that is related to humans, so +5 animal +2 mammal +2 related. The options here are, I'd say, as versatile as wildshape, just at different things.

Giant as mammal is debatable since it's a separate subtype; much like Reptilian. Specific broken magical mammal? That we're sure is a mammal and not some magical aberration? Something worth burning a feat over or losing spell casting for?

You don't lose spellcasting except when in form.
