The playbooks are lovely, I'm enthralled by the interplay between their attitudes towards myth and really hope I get the chance to see at three at my table some day. The traits are excellent, I always welcome a little sea salty flavor for NPCs. But the part that REALLY hooked me was the natures, specifically the Leviathan nature. I can't wait to use everything in this collection. Also the layout and design is lovely, it's so nice to look at.
