I'm a first-time DM running Legacy of Fire under PFRPG. The party just reached level 2, and I noticed that, not only have they not found any scrolls or spellbooks, there aren't any in this entire 1/6 of the AP. (For those not familiar with LoF: this part of the AP takes place in the desert without any easy access to settlements or shops.)
I feel that this is a problem for the Wizard in the party, because while other players are/will be getting fun new magic weapons, armor, trinkets, etc., he can't learn any more than the two spells per level granted by his class. Would it be un-balancing to pepper their treasure with random scrolls and spellbooks for him to fill up his spellbook?
