Includes eight Disease cards: Pox Scurvy Typhus Beriberi Fever Sailor’s Bane Sea-Sickness Piratitis! At the start of the game, you put one of them into play and shuffle the rest into the deck.
Each disease has a different ability, and they affect all players. Disease cards don’t count as permanents, and whenever you draw one it goes into play immediately.
As your action in a turn, you can shuffle all Disease cards from play back into the deck - this is the only way to get rid of them, but it might be worth it...especially if all eight are in play!
