It Is Recommended To Farm Story Events
We highly recommend clearing the 'Ground Zero: The Silent Project' Story Event, as the rewards are valuable and worth collecting. Players can earn Legendary Hero Tickets, Rate Up Hero Summon Vouchers, Skill Enhancement Stones, and more. Since this event is only available for a limited time, it should take priority over permanent content.
 Tips! | Battles in the Story Event do not count toward the 'Repeat Battle' missions in the [Ruby Farming Expedition] event. |
