A myriad of questions about CCs!
How do you introduce compendium classes? Is it right when the “prerequisite” is fulfilled? Do you wait until a level-up moment? Do you show your players “this is what CCs are available and one of the ways to become eligible for use” and use it like a magic item (like more of a “quest reward”)?
How do you choose a compendium class to offer? Do you have one in mind (e.g. a pirate themed CC) going into a session/campaign and look for an opportunity to offer it? Or is it more of a player-driven exercise; where the players decide they want to make an impact on their character’s growth using a CC?
Do you allow more than one character to take the same compendium class? Skimming through a bunch of them, some of the prerequisites seem like something the whole party might do together – who gets offered the CC after it’s completed?
