How exactly will the items for girls be improved ??? Will it be necessary to give them items from the inventory or will each have their own specific set, depending on the rarity? Will you need items from your inventory to upgrade? For example, you invest the usual 1 conventional unit, invest the rare 2 conventional units, invest the epic 4 conventional units, invest the legendary 6 conventional units, invest the Mystical 10 conventional units, for example? Does anyone have information ???
