This is a really good product for those looking for new spells, new archetypes, alternate spell systems, or different treatments of magic levels. The writing is generally conversational in tone and the information is presented clearly. The first few sections in particular are very interesting reads; I particularly liked the treatment of the low magic setting and the inclusion of archetypes more fitting such a setting than the ones presented in the core rules. Definitely well worth the cost of admission.
