From publisher blurb:
Echelon Reference Series: Inquisitor Spells is a simple document that collects the inquisitor spell list, and all spells in it, for easy use. The spell lists are broken up by level and school, and the spells of each level are grouped together and organized by name.
This is a subset of the entire book, containing only the 2nd-level inquisitor spells.
This is the 3pp+PRD version, containing information from the PRD and from select third-party products.
