YIELD reward from [seeds-and-farming](https://docs.cryptovalleys.io/the-game/seeds-and-farming "mention") accrues in two forms:

* **Unlocked YIELD:** A base YIELD reward is immediately harvestable.
* **Locked YIELD:** In addition to Unlocked YIELD, players receive Locked YIELD, an in-game currency that can be used during special events or unlocked through particular game mechanics attached to [expeditions](https://docs.cryptovalleys.io/the-game/adventurers/expeditions "mention") (starting with Phase 2), and the [sage](https://docs.cryptovalleys.io/the-game/locations-and-npcs/sage "mention") (currently live).

The reward rate of Locked YIELD depends on a weekly multiplier that decreases as the game ages...
