Could you please explain in more detail about the educational book? I'll read it, get a perk, and then choose alchemy plus one of the potions for that perk? I wouldn't mind playing an alchemist, sort of role-playing, and it would be profitable because I'd be "immortal."
But I also got another skill point from leveling up, so I could take two potions. Because the other option for spending it is to upgrade Light Arrow (meh). Or I could just sit on it until another skill point drops, and then go into elemental magic or somewhere else.
