Falling leaves Festival!
A traditional autumn festival starts in the world of Sphere! While the event is active, you can loot a golden leaf fragment from any mob that is not 3 levels higher or lower than you and combine them to get a reward. Following the tradition, you will combine the fragments and in the end get the crown of golden leaves that will grant the blessing of the autumn during the entire event and a week after it's over.
Don't forget: if the member of the opposite faction kills you, they will get half of the golden leaf fragments you've already collected!
You can obtain additional fragments completing daily quests in Cinderkreg or Hellsong tavern.
