From the back of the book:
Blood & Tears includes rules for the guza'dun: the ven parlor game. Equal parts dinner party, improvisational theater, historical re-enactment and always an opportunity to make trouble.
And the ven never turned down an opportunity to make trouble.
These are the rules for live action Houses of the Blooded. And you have never played a live action game like this before.
Blood & Tears includes:
Transferring table-top characters to live action characters with no mechanical changes
Using Style instead of dice
Both Friendly Game and Cut-Throat Game modes
Tons of player and Narrator advice
