Triton’s aquatic physiology allows him to place Water tokens across half of the Locations in the game, giving him an advantage in those places. Communing with water grants him free Attacks, but also free Wild Actions if there’s a Water token in his Location. These Water Locations can also be used as safe havens, allowing him to evade all damage when hiding underwater.
