Message: <blockquote data-quote="Doug Sundseth" data-source="post: 4812245" data-attributes="member: 52196">The costing below assumes use by a character who can cast the spell normally.  If you prefer, you could use another pricing model, but this seems the most obvious to me.I think the best reading is that the spells would be cast at their base levels (casting level being covered under, "Treat each spell use as if a scroll were being employed, for purposes of determining casting time, spell failure, and so on.")The expectation value for the number of uses for each page is 10.  The base value of the first page is thus 10 * 5 * 9 * 25 = 11250 GP.Subsequent pages will each have a base value similarly determined:4th level (5% chance) = 10 * 4 * 7 * 25 = 7000 GP5th level (45% chance) = 10 * 5 * 9 * 25 = 11250 GP6th level (30% chance) = 10 * 6 * 11 * 25 = 16500 GP7th level (15% chance) = 10 * 7 * 13 * 25 = 22750 GP8th level (10% chance) = 10 * 8 * 15 * 25 = 30000 GP9th level (5% chance) = 10 * 9 * 17 * 25 = 38250 GPUsing the weighting above, a random page will have an expectation value of 18687.5 GP, and the book will have an expectation value of 123375GP.I would give a discount from this value, since only one spell is usable at a time and there's no way to know how useful the next spell will be.My value would be somewhere between 60K and 100K, putting the sale value somewhere between 30K and 50K GP.  (Always assuming an available buyer, of course.)Note: The fact that the book can be used by a non-caster to cast spells seems like it would approximately counter the reduced number of castings for such casters.</blockquote>
