v.137 - Unleashed Update Notes

@the people who are complaining about the attendance event; you only need to log in for 7 consecutive days, and the event runs from the 19th to the 2nd. So it isn't a big deal if you missed one day at the beginning.

That's not how I understand the patch notes.

Attendance Check Event

June 19* - August 13

Requirements: Lv.13 or above

• The Attendance Check Event is divided into 4 seasons, each covering a two week period.
  
• Completing a full season of the event will earn special rewards.
  
• Players participating in the event must accept the quest each day through the calendar notifier on the left, clicking on "Challenge" to start.
  
• Defeat 300 monsters and turn in the quest through the star notifier.
  
• Players will earn one Premium Dice for each Attendance Check completed.
  
• Completing 7 days in a row will earn six Premium Dice and one Occult Cube, in total.
  
• Players will also earn 5 Unleashed Coins for every day of the Attendance Check they complete.
  
• Players who logged on on June 19 will automatically receive the stamp for that day.
