It goes through what happens as a characters humanity degenerates and how and why they switch to a path

This is a very useful tool for anyone running a Sabbat campaign or character.

The only reason that this book doesn't merit 5 stars is that quite a bit of the material presented here has appeared in other supplements. It has been expanded and clarified in this book and if you don't want to go through half a dozen supplements for some of the rarer paths then you will find this indespensible.
