Medieval Methods

From: Huntress
Description: Judging by the drawings in the Doctor’s journal, he selected very primitive methods to hunt the Moon Werewolves. Pity. I thought I’d get some clever ideas from him. There’s something squiggly drawn here. It’s a "wolf hook." But nobody has used one like this since the Middle Ages! Look for it, maybe the Doctor made a Wolf Hook with a secret?
Completed: Just an ordinary Wolf Hook. One end is fixed to a tree, and bait is placed on the other end. But werewolves are much smarter than ordinary wolves. Didn’t the Doctor know that?!
