From publisher blurb: The spell point system introduce in Houserule Handbooks: Spell Points was designed to be flexible, simple set of rules for replacing the normal spell slot/spell preparation system used by spellcasters in the Pathfinder Roleplaying Game Core Rulebook with a different resource management system – spell points. Though both successful in this goal and quite popular, the book did little to show how the spell point mechanic can be used to create new options and mechanics beyond just tracking spellcaster resources. While the system has received a small expansion in [Houserule Footnotes: Spell Point Feats], this product is the first effort to grow the spell point system to be a more comprehensive option able to cover all spellcasting related classes, archetypes, and combinations, as well as provide new ways that spell points can be used to add more flavorful options to a campaign. As an expansion of the original product, this book requires the use of Houserule Handbooks: Spell Points.
