Curse of Strahd

Curse of Strahd content not available. Only available items are monsters and magical items?

Try this:

https://www.dndbeyond.com/compendium/adventures/cos

Sorry it brought me to the same page. I have no access to the book content. Only the options to purchase items and mosters. There is no access to the actual contenr in the book such as info about vistani, locations in barovia, ect.

Try to clear the cache, then.

Otherwise, the last option would be to contact support:

Do you mean that you are looking for a way to buy compendium content for CoS, or that you bought CoS and cannot access compendium content ?
