From publisher blurb:
WARNING: Aside from some art, there is no unique content in this book that you won't find in the original playbooks.
Whether a player botches their last breath, or you are looking for something "fresher" than a fighter, wizard, or variation thereof, death doesn't have to be the end!
The Playbooks of the Dead is a compilation of our four undead playbooks — the ghoul, mummy, skeleton, and vampire — all in one book.
In addition to customized, letter-sized sheets for each class, you also get a 78-page digest-sized book that contains:
Everything you need to know about each class.
Excess moves that we just couldn't fit on the sheets.
New weapons, armor, dungeon gear, and magic items.
The vampire spawn compendium class.
A pair of vampiric monsters.
A behind the scenes look at each class, including ways to tweak the them, and an explanation, clarification, and/or interpretation of some of the potentially confusing moves.
