My question is simple. If a group of seekers gets a hold of these in a module, and has the time to use them, what happens? Does the bonus apply for the rest of the adventure, and then disappear afterwards (assuming they don't pay for it if its on the chronicle)?
I would treat them as a consumable. That is, you use them (for free) during the adventure, and then have them available to purchase afterwards. (And all ongoing magical effects end at the conclusion of the module.)
If you're going to buy these things, the +1 bonuses don't stack with each other right? Even though 4 +1 books cost the same as a +1 book, if you want a +4 to your con you have to save up/have the fame for a +4 book.
