Lucky Ring

The Lucky Ring is a special equippable accessory item that can be obtained in the Stardeer Coffee in Wendy Wu: Homecoming Warrior Kick-in Challenge. As with all special items obtained in there, Nina Wu shows up to taste a new type of brew that has not been made before. Nina leaves behind the Lucky Ring if this is the second time the player has brewed a unique type of coffee, after the Amulet Wallet. If a Yin Warrior equips the Lucky Ring, he or she earns an EXP bonus if he or she wins the battle without taking any damage. The EXP the Yin Warrior will earn will be doubled.
