I don't have a smart phone. To access the grimoire, I need to leave my console and switch to my PC. This is less than intuitive, and is a severe design flaw, imo. Though HoW is much better than TDB and the base game with regards to story. There was some actual character development throughout those missions, and the characters spoke on their history and provided commentary on current events much better than any other point in the game. I'd much prefer to hear about the history and motivations of Skolas than "I don't have time to explain why I don't have time to explain..." Still, the grimoire being separate from the game itself is a huge oversight.
