It was given to Star Butterfly along with the Royal Magic Wand and contains magic spells that have been mastered and written down by previous owners of the wand. Unfortunately, the book is a complete disorganized mess, which can be a problem when searching the pages for a certain spell. For some strange reason the table of contents is found in the middle of the book adding to the disorgnization.
- Releasio Demonius Infestica: Written in an ancient language, contains a spell that supposedly heals bones. However, when cast incorrectly, it can transform a person's arm into a tentacle monster. "Releasio Demonius Infestica" roughly translates to "Release the infesting demon" in Latin.
- Returnio Armius Normalrino: Also known as the Reverse Tentacle Spell, this page contains the counter spell for the Monster Arm spell. The spell is also able to create functional arms or transform objects into arms.
- Warnicorn Stampede: Invented by Star's ancestor, Skywynne the Queen of Hours, the Warnicorn Stampede spell can summon a stampede of Warnicorns. The chapter for this spell contains an eight step Incantation Dance, which is required when casting the spell.
- Eclipsa's Chapter: Dedicated to Star's ninth great grandmother Eclipsa the Queen of Darkness, this chapter in the book contains dark magic. Often chained up to prevent anyone from reading it unless Glossaryck unlocks it. One of the spells in Eclipsa's chapter is known as the "All-Seeing Eye"; a spell that can be used to spy on anyone or anything.
- A real-life Book of Spells was published on September 11, 2018 titled Star vs. the Forces of Evil: The Magic Book of Spells.
