Just received, having ordered last week.
Like it. A mix of spells other than fighty ones, such as "creating pools of dice to call on" (representing foresight) to making the bad weather avoid you (rain on others, I have a little zone of not being rained on thank you).
Definitely a Player expansion. Some GM use for NPC's but not nearly as much. The "fun" in many spells defintely "fun as a player" (ooh look at the way I can fiddle dice).
Hope they keep this up and keep mixing in ones more GMy, and themed aroudn things about than colleges or faiths such as all sneaking con artist thief oriented or all fighty, riding, jousting, being a knight or all fanatical inspired crazy but maybe blessed zealotry witch hunter etc.
