In the fight with Hosharr earlier, my mage had been knocked out. I decided the fight was tough enough, but nearly finished enough, that I'd accept him being unconscious for now, and kill Hosharr, and loot his lair. In looting I read the book there that provides the terror spell . . . again with my mage unconscious, so the others gained the benefit, he did not. After reviving him back at Silvar, I returned in order to get him the spell as well, but now I'm told that I learn nothing new from this spell book. I've tried clicking the book with him selected, and with him in the first party position, but no luck. Does anyone know a way I can get him the spell still? I know there's 2 levels worth to buy, but without this book I never get level 3.
I really want to know in case the same thing has to happen again in the future, there's good spells still to get for both my mage and my priest.
