Hi Pythix, When it comes to compendium resources you want to do the following: Go to <a href="https://roll20.net/welcome" rel="nofollow">https://roll20.net/welcome</a> Then click on the name of the game (not launch) Next, click on Settings then Game Settings. Finally, go to Compendium Settings and verify that any compendium resources you want to use are green (enabled). If you make changes don't forget to save the compendium changes, then save the page as a whole. With that said, I took a look and it does not appear that Elminster's Candlekeep Companion has a compendium. You will have to add the sub-classes and spells manually on a per-character basis. An explanation: The compendium is very technical and requires programming knowledge. Many of the smaller publishers will not be able to do that or afford the programmer(s) to do it for them so will simply publish the information in Roll20 for you to add to a character manually. Thankfully, adding it manually is pretty simple. Note: There is a request in the request forum for a simpler form of Compendium that will enable folks to make compendium entries easier. But that has not been implemented at this time. If you need help adding a class, subclass, or spells to your character I can walk you through that, let me know.
