Can more than one instance of "Secret Page" be cast upon a page at a time?
For example: My character picks up a (non-magical) scroll, advertising the existence of a well-known smith. He then casts "Secret Page" upon the scroll, and proceeds to jot down a funny drawing of the town mayor. He then proceeds to cast "Secret Page" a second time, this time recording vital notes. He gives both instances of "Secret Page" the same 'special word'. Let's say, in this case, 'Barbeque'.
A stranger picks up the scroll. He sees a funny drawing of the town's mayor. Suspicious, he starts randomly guessing special words. 'Barbeque!' he shouts, and suddenly the scroll transforms into... an advertisement flier for a smith.
Because the stranger is unaware of the second 'secret page' casting, the vital notes are concealed. Only the original character, which Knows of the second secret page, can At-will transform it into the secret notes he desires (unless the stranger guesses there is another instance).
Is the above situation a viable strategy that abides the RAW?
Anyone? Bumping once, in hope...
Final call... otherwise considering this a genuine and RAW-friendly strategy, that I will bring to the GM.
I just looked at the RAW and for good measure looked at the OGL version upon which the PFSRD RAW is based. No change that I can see, so no accidental trouble there.
Now, parsing the RAW, it appears that is the original page that is the secret and the secondary page that is the facade.
To use your example, let's say you have the smithy flier. This is the original page, which becomes a secret when you cast spell and hide it. You then put a funny drawing of the mayor on the new "blank page." It detects mild magic. If you say "Barbecue" the secret page with the smithy flier is revealed, hiding the funny picture of the mayor. The funny picture of the mayor only appears when you hold the page and will it to show something else or otherwise hide the original contents. If you say "Barbecue" twice, the page with the funny picture of the mayor disappears completely and you're left with a nonmagical advertisement for the smithy.
Now the question of whether the facade page, which is the second one with the illustration of the mayor upon it, can be treated as original and hidden itself with another casting, basically nesting them like Russian dolls.
From what I'm seeing, this should work. You cast it, hiding the magical page, and create a new page, making the first magical page secret. Then you have your page that you put your vital notes on. You say "Barbecue" once and it flips back to the funny drawing of the mayor, and you say "Barbecue" again and it goes back to the smithy flier. If you hold the smithy flier and will it, it reveals the funny picture of the mayor, and if you continue to will it, it reveals the vital notes.
The only problem here is that the password is protecting the original contents, not the information stored on the magical facade, and doing the double-repetition to remove the spell destroys the facade and its contents, but not the original contents.
That's what the RAW says, but honestly only an insane wizard would make the spell that way, so it's easier to just say that Secret Page makes a secondary page that is accessed with a password and can be destroyed by a double repetition of that password, and moreover wizards with a decent Spellcraft can choose different passwords for revelation and autodestruct, and moreover choose "at holder's will" for any of these.
That's what the RAW says, but honestly only an insane wizard...
If I'm not mistaken in my personal reading of the spell description, Speaking the word 'Barbeque' a second time is not required; Saying it once gives the reader full At-will access to Both the "Secret Page" instances. Thus, the whole debate is whether or not I can select One secret page to be displayed above another, and whether or not I can Switch them at will, if I'm aware of the others' existences. This thus allows the stacking of Multiple 'Secret Page's, and all their information.
Thank you verily for your answer, though, sir Kevin Andrew Murphy. ^_^
Naturally, speaking the word Again erases it... But sometimes, information is much safer Lost than it is Stolen. That's what this whole project is based on.
The second, more practical use is quite a bit more complicated, and possibly a more baleful result: Pathfinder specifically entails that Secret Page can 'hide' one spell with another of equal or lesser level. This leads to the possibility of a 10-page password locked spellbook, containing every possible spell in a wizard's arsenal, able to be viewed At will.
Considering the cost in time, this may not seem all too worthwhile; But it is a considerable method to have a Spellbook that's near-foolproof, will be Destroyed before others learn of its secrets, and most importantly, Be only 10 pages, for what is essentially a time-consuming blessed book without the Free spell writing. The only downside; It is vulnerable to dispels.
Edit: As an added bonus, Only a wizard familiar with a spell's existence will be able to view that spell with this password-protected book. This can lead to some extremely fun role playing and plot ^_^ Similar to having a book "With all the answers, if you ask the right questions". Make it intelligent and vocal for even more fun.
If they detect mild magic - yes Secret Page "...A detect magic spell reveals dim magic on the page in question but does not reveal its true contents"
Here's the big question here. Why would the stranger start randomly guessing secret words? Do you have compulsions to start yelling passwords at every flyer you pick up?
...Parchment is Expensive! D= I'd be suspicious if someone had seemingly lent out a 2$ piece of paper for their child to doodle on...
Anyways. That aside;
the whole point was to emphasize someone discovering that there Was indeed a 'Secret Page' spell cast here, however, Has no awareness of secondary, tertiary, or more instances of the same spell; Thus, if they're unaware of their ability to at-will it to a different 'Secret Page', they'd most likely Only see the Hidden (Original) Content; a Blacksmith's flier.
By the way, you still did not answer my original question. Do you yell passwords at EVERY flier your characters see? If not, why would the hypothetical stranger start barking random passwords in your original example?
Because he was a homeless stranger rather bent on making the slightest bit of coin from a piece of treated animal skin with a childish doodle. Also, he jabbers on his free time Anyways. Which is all the time. 'Cause he's homeless. And he wants a barbeque dinner.
And Damn right I will, from now on. Just for you.
Now can we please simply look at the Mechanics of the situation at hand? XD
