  • This drop calculator assumes that you collect your loot in the Campaign at least once every 9-10 hours.
  • Due to the instability of the drop rate, it’s best to use this calculator from the 2nd day of the event.
  • The timer is auto. You can set is manually If you want.
  • The calculator doesn’t count the last 24 shopping hours.
