An expansion to Michael Iachini's 2013 game of rivalry and potions, Chaos & Alchemy. Players now add new elements to their laboratory in a bid to become the greatest of all alchemists and achieve fame and glory throughout the land. New Substance cards will allow you to skew the rules in your favour, rerolling dice, stealing element cards from other players and seizing control of their creations. The base game is required to use the Substances expansion.
Chaos & Alchemy: Substances supports 2–5 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.
