From publisher blurb:
Echelon Reference Series: Druid Spells is a simple document that collects the druid 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 4th-level druid spells.
This is the 3pp+PRD version, containing information from the PRD and select third-party products.
