Greed Island arcEdit
Gon and Killua lose all their Jenny and clothes to help a bandit's sick child, even though the child was just an NPC. They do not receive anything in return. On their next visit, Gon has an idea on how to cure the sick child. When they return, Gon asks them to transform into cards and uses his Paladin's Necklace to heal all of the sick villagers. When the villagers are healthy again, they reward Gon with the "Wild Luck Alexandrite" card.
