Manny L. said: According to the Adventures in Rokugan marketplace item I just checked, it states as follows (note the italic underlined highlights I have added): Accessing your Content Addon : This product includes an Addon that can be added to any new or existing campaign . On the Game Details page of the desired game, scroll down to the Game Addons section. Select the desired Addon from the dropdown menu and then click add to game. Everything from the Addon will be available next time you enter the game. Compendium : You can access all of the rules, items, and creatures from this product in the in-app compendium , as well as clicking on "Compendium" where "Buy Now" was located prior to purchasing. Art Pack : You can access the Art Pack under the Premium Assets section of the Art Library in-app. These assets are only available for in-app use. Which Character Sheet should I use? All D&D 5e content on Roll20 uses the D&D 5e by Roll20 character sheet . Well, poo! There's no fool like an old fool! Thank you, Manny - that worked... One quick question, on Compendium Sharing, I guess I only need the Rokugan options? That is, I don't need the PHB, DMG, MM, etc.?
