Entropy: The Ronin is an expansion for the card game Entropy. The expansion makes it possible to play as a new character: The Ronin. The goal of the Ronin player is different, it's about complete another player's world. To do so the Ronin can use Wild Fragments, but also have two unique character abilities (one more skill then the other players). Although the Ronin does not have an own world panorama, the two ability cards combine makes a panorama. The expansion also adds a set of action cards to fully support six players.
Entropy: The Ronin expansion supports 2–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The catalogue lists Entropy: The Ronin expansion for ages 12 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone.
