I saw variations of this question while scrolling through the sub but none of them fully answered my question so I'm making a new post. If I am a DM of a campaign and I buy a book, to what extent can I use the materials in it in a campaign where none of my players have bought anything? Can they make characters for that campaign https://showbox.bio/ using the classes/races I've bought? Can I build encounters with monsters from something like the MM?
