Daniel S. said: If I am a DM in a campaign but not the GM will other DM's have access to Volo's when they create campaigns or just me? And everyone keeps mentioning the compendium. If I buy this will I receive a Page by Page copy? Like a PDF or something. Hi Daniel -- If you purchase Volo's Guide on Roll20, you will then have the option to access Volo's Guide content within any game that you create on Roll20. You could, for example, create a game with access to Volo's Guide, then promote someone else to be the GM to that game. You are not required to GM the actual adventure, to continue to have access. The Compendium portion of the module refers to the Volo's Guide expansion to the main 5th Edition Compendium . All written content from the original book version of Volo's Guide to Monsters is accessible via this Compendium expansion. Once you've purchased the Roll20 edition of Volo's Guide, you can access the Compendium entries, either on the web Compendium or via the Compendium tab within the Roll20 tabletop. There is no PDF or printout include in the Roll20 edition.
