Lucky Spin gives you a chance of winning Heroes or Skins by spending or 1 for 1 draw or for 5 draws each time. Rewards will be refreshed weekly. Heroes will be refreshed biweekly (once in two weeks) or skin will be so.
Free Chance refreshes every 48 hours. A Skin that you have already owned will be converted into Special Skin Fragments accordingly. Heroes won't be unlocked for you when you obtain skins in the event. Unlocking heroes are required to use their skins obtained in the event. The items in the Treasure refresh regularly. When your Emblem has reached Max Level, the Emblem Fragments you obtain will be converted to Magic Dust accordingly.
The congratulations shown beside the rules are the records of the rewards and they are not real-time.
