Plenty of new content, all thought out and designed with unique twists. However, promo material promised Vestiges of Divergence (strong magical items from the Critrole D&D series) and while there are plenty, none of them seem to be ones that fans would know of from the series, which is disappointing to say the least. Additionally, while the book adds a whopping 15 new spells, based on either Chronomancy or Gravimancy, none of them are available to classes outside the specific wizard subclasses added in the book, not even wizards of existing subclasses can access these spells, meaning that anyone wanting to use these new spells would need to make an entirely new character just to see them. Oh, and the 1 new race, is just the Eberron Orc from the last book with a longer lifespan.
