A Star Chest is where your extra progress goes when you collect Duplicate Cards in the Collection.

Whenever you get a Card you already own, the Card is turned into Star based on its star value. These Stars are automatically added to your Star Chest.

Once your Star Chest fills up, you can exchange it for one of three (3) different types of reward chests, each giving you valuable rewards to help you progress further in the Collection.

The more Duplicate Cards you collect, the faster you build up your Star Chest!
