This is a great addition to the OSE ruleset. While it includes Druid and Illusionist spells, these spells are also used by the Bard, Ranger, and Gnome classes. For those classes this book is all you need for spells (in other words: theres no "see the Cleric and Magic User spell book" text). Also, each spell is presented in a bullet point format that is easy to use at the table. The art is B&W, but use is made of green as an accent color that is especially handy in charts (familiar to OSE and BXE readers).
