The "Mind Blank" spell: what exactly does it do? The thing is its language is not as technical as I would expect, leaving me wondering which parts of the spell description are fluff or if it's all mechanics. More specifically the part about "One character’s thoughts and emotions can’t be read.": is this a mechanical effect? Or is the intent of the spell to shut out magical methods only?
Given that there's only one other sentence of Effect text, and it begins with "Also," I'm inclined to assume that "one character's thoughts and emotions can't be read" is intended to be a mechanical effect. At least one of the two sentences must be mechanical, and the use of the word "also" to begin the second implies that both lines are of the same type of content, so they must both be mechanical.
However, the precise meaning of "can't be read" is pretty fuzzy. Could mean only literal mind-reading (ie, magic), but it could also extend to other extraordinary methods of getting insight on a character (eg, Cold Read) or even simply using Sense Motive checks to get a feel for a character's mental state. I have a suspicion this is one of those things left deliberately vague for the GM to make a judgment call.
EDIT: Forgot I came in here to ask a question myself.
What would the appropriate check be to make an object or piece of scenery look like something it's not? Can you use Disguise on objects? Or would it be some kind of Crafting check (perhaps using the Craft skill with the Mask check rules)?
