Nano-tritium ### Polygons Players with Genesis Collection Heroes can receive Polygons as a part of their daily victory rewards for every Hero on their team. The number of Polygons each Hero can receive per day is limited and depends on their Rarity: Common Heroes get 1 Polygon per day, Epic Heroes get 3 Polygons per day and Legendary Heroes can get up to 10 Polygons per day. Polygon is an expensive game resource and will be used for other game activities beside investing.
