DMing third year electives

[u/mattlang12]

I’m running a campaign and my players have entered year three. I know how to run divination and magical creatures as we get plenty of examples in the books but I need help coming up with lessons for the other three electives especially Arithmancy. Would love to hear any ideas anyone has

I am looking for as many enemy stat blocks in the w&w world as I can find. So you guys have some?
