Collect Wishes randomly by opening Chests and tapping Fallen Stars. More Wishes mean more rewards in your Dragon Shrine Chest.
Open your Dragon Shrine Chest with 200 gems at any time to collect your rewards.
If you reach Level 6 but don't purchase the chest, a timer will start and you'll have 24 hours to purchase them. After 24 hours, it will reset itself and go back to Level 1.
