Controversial issues and their resolutions.

P.S.: I personally don't understand another point. Why is a Guild required for wings, and it's required for scrolls, but not for magic books or pandors. Where's the logic?

Elemental books are relics, and the generator provides serious protection for them. If you succeed, you get a prize. Pandors are also guarded accordingly to their content. To get all the fire, you need to break through 87 naga (I had this in a recent game). I think this is decent protection for that prize. And the generator identifies scrolls as a valuable object. The higher the scroll's magic level, the stronger the guard (but it doesn't match the value of the scrolls). But how do you explain to the generator that a city portal scroll is much more valuable than inferno, or that an explosion is sometimes preferable to an entire book of some element? That's why this restriction appeared. :)
