I've slowly been painting CoS minis for my group. If you're in to painting minis this is a starter list that I used:

I went with these 3d printed minis from Etsy for my night hag coven.

I went with these Nolzur's werewolves from Amazon. You'll need a few of these.

I went with these Nolzur's blights from Amazon. You'll need a ton of these.

I went with these Nolzur's death knight & helmed horror for my revenants.

That's as far as I've gotten as I already had a pretty good supply of wolves, direwolves, skeletons, zombies, ghouls and ghasts. It's kind of a never ending rabbit hole once you start.
