“For a 6th level spell, you darn well better be able to move the parts! I'm pretty sure the lower level illusions specifically state you can, so you can on this spell, too.”
Sure, could be. But an illusion of a book with its pages turning is one thing; saying the every page is a perfect rendition of, say, those of Moby Dick, seems like a whole different level of recreation to me; how could anyone build such an image in their mind? It is interesting, and I’m not saying I get a firm idea from the rules, more that it is something that isn’t too firmly described.
“I don't think spellbooks qualify as magic items. They certainly aren't the same case as a scroll.”
Well, my thinking is that when you find someone else’s spellbook, it functions quite a bit as though it were a pack of scrolls. Do spellbooks radiate magic? I don’t recall. I think they should, but even if they don’t, they certainly function magically- spells can be cast directly from them, or transcribed, just like scrolls. Are they magic items? Again, I don’t know. I actually meant magical items in a broad sense, not magic items in the technical sense.
At any rate, there is clearly a different take, there, and I agree that there is sound logic to it. I could go either way, really.
Cheers
