I just have a quick question, and I hope this is all right. I'm writing a bit in my Marauder Era fic and I'm wondering what sort of potions you guys think Slughorn would have his seventh year class brew up a few months before the exams. Like, what would be a difficult enough potion for seventh years at that time? I'd like it to be a potion that will need to simmer, at least for a short while, to give my characters time to talk in between.
I think that's it... haha. Opinions are good and much appreciated. Thanks!
