In both the compendium on the website and the compendium inside a game session some spells are available and the links bring a PAge not Found error For instance <a href="https://app.roll20.net/compendium/dnd5e/Encrypt%20%2F%20Decrypt#h-Encrypt%20%2F%20Decrypt" rel="nofollow">https://app.roll20.net/compendium/dnd5e/Encrypt%20%2F%20Decrypt#h-Encrypt%20%2F%20Decrypt</a> Other spells instead lead to sections of subclass features of the same type like Iron Mind. Overall this book has terrible Compendium function and formatting
