That caricature of Nick did him dirty, ngl. That being said I love the solo sessions contained within a wider campaign, I feel like it works so well. Probably will adopt it for myself on like off weeks that I know are coming.
Where are rules for the upcast blood magic system? I can't seem to find any mention of them online, is it a 2.neal thing that hasn't been touched much or is it buried deep in a book somewhere I've not been able to find?
Single player sessions are a little cucked. You can't make big plays without the rest of the party, so you're stuck doing mostly administrative tasks. Exploration of the character's motivations is probably the best way to spend these episodes
The Potato solo session got a little dicey at the end. Almost thought he wasn't going to make it back. I think they mostly are just for character building and that's not a bad thing.
