Just a quick example for the poor documentation of the game:
Found a tuning fork. The description doesn't say too much about it, the manual nothing at all. But it turns out, if you use them in a fight agains trolls, they run away. Yeah, figure that out by yourself.
Another: Found a spell shop in a village, with around a dozen spells. Some of them are explained in the manual, but most of them are not. And you can't check the spell discription until you buy it, right clicking on it in the shop doesn't help. So you can buy them for hundreds of gold, just to figure out that you don't need after that. Sure, I can look them up online, but still...
