Merchant is a family trade that the player can give the character that they play. The merchant may not have many items at first, but once his or her production level rises, the player gets better discounts and access to better materials and items to buy. The player can even sell items at a marked up price to their father depending on their relationship with him. Other players can use the 1st player's father's expanded inventory during the game, but they will not receive discounts.
