Well... everything's in the title.
I remember seeing this somewhere and that it act exactly like a tome of magic except it is used to learn necromantic magic.
We're starting a campaing and I want to know in wich book/article the book is so I can show it to other players.
I plan to buy this book as fast as possible to get a second spell caster for my Necrarch warband (from sylvania setting).
Bad plan? I guess...
