Fallen leaves (2015)

Fallen leaves are the components of the Pet of Autumn, and are won through playing Treasure Hunter, or awarded while Farming. 600 of them are required to create the pet. They are only tradeable in equal quantities for flourishing seeds, lush blossoms, or charred branches. These items are completely removed from the game two weeks after the promotion ends.

The number of leaves obtained appears to be based roughly on the amount of experience gained, rather than the number of actions the player does. 20 leaves were also rewarded for handing in a Daily challenge.
