I really dig the patrons and the follow-up roll that adds complications, very cool. I don't know Traveller, but I assume Sorcery rules aren't in there which makes your add-on incredibly concise and neat. No small feat.
It's nice to see another typst enjoyer in the wild. I did all my layout in typst as well. I had seen Idraluna's typst work before, so when I saw their name in the credits then saw the document itself, I inspected the PDF to confirm my hunch. Good work!
