Okay, I'm not understanding how to finish this event. I get that the repeatable quest continues until end of event.
But what I mean is, the main reward for the quest is a Cherry Blossom Necklace. But how do you get it? Is it a random drop from those sacks you get from the repeatable quest? Or do you have to do a certain number of repeatable quests? Also, is there an achievement for the event like there was last year?
