In Vino Morte: Caseus Vitae

A three card expansion for Chris Anderson’s In Vino Morte.

From the publisher gameplay summary:

When dealing out cards, you may also give out cheese cards to whoever you choose.

Each player gets a face down glass as normal, and some players may also get a cheese card.

On a player’s turn they can drink or swap glasses as normal, or choose to steal cheese from another player.

Players cannot give cheese away or have more than one cheese at a time.

When you drink, if you have cheese, the results of your drink are reversed: Wine will kill you and poison will not.
