Most likely its BG2, as it isn't in BG, or IWD for that fact. Yup, only one Fireball scroll that I've ever come across in IWD. I'm no expert, but I've played it a bit - if you no what I mean. In fact, most of the good spells after level two only appear once as far as I remember. Bl**dy annoying that. So count yourself lucky people. You could be stuck in the frozen north of Faerûn without a single fireball to keep you (or the bad guys) warm.
