So I finished the third book. It was so much better than the first two (not that the first two were bad). Though I still have a kashya on it:
In the beginning of the book, Drum Billet is walking in the rain. We are told:
[Y]ou could tell he was a wizard, partly because of the long cloak and carven staff but mainly because the raindrops were stopping several feet from his head and steaming.
Yet towards the end of the book, Cutangle is walking in the rain and he gets soaked until Granny Weatherwax tells him to move between the drops. Now why couldn’t Cutangle do whatever magic it was that Drum Billet did to stay dry?
