I was thinking about how to alleviate your issue partially. What if instead of going through the entire library of scrolls every time, the book would draw a “hand” of say 5 scrolls that you’d use up and then it would shuffle and draw 5 more? If the book told you which 5 scrolls were in the hand then you’d have the ability to plan what to do with them. For example, having retribution and rage and lullaby in your hand would be a very powerful combo to use against the Dwarf King. Much better than ID and remove curse (especially if you don’t have anything left to ID).
Yes, this is clear enough in the long run. But the question is: will the transition happen fast enough to prevent a climate change catastrophe?
