Potioneers Secrets

One of the best known collection of "sercets". This booklet is considered the end all collection of preperation techniques and tipps about "shortcuts" in potion making. It can be found in almost any libary with some works from that field and many private collections proud themselves by having a copy.

There are rumours about a much more "interesting" version of this book that contains dubious information and a few obscure recipes that are not found in the regular edition.
