Advanced Potion-Making
From UnknowableWiki
Advanced Potion Making is a book written by Libatius Borage and requested by Professor Slughorn for his Potions course in Harry's sixth year which is required for NEWTs level. A new copy of the book costs nine galleons at Flourish and Blotts.
The Half-Blood Prince owned this book before Harry did.
This article has to be revised, because it needs more information about the Prince's notes.
