Every part of Sol Valley feeds one loop:
- Spend YIELD on seed packs. Most of the price is burned, 0.5% flows to Sol Well stakers, and 1% goes to your sponsor if you have one.
- Plant and grow. Each seed carries a share of its pack's price. Its rarity decides the growth time and the payout multiplier.
- Harvest. You receive unlocked YIELD, extra Locked YIELD, Produce, Farmer XP, and sometimes Sol Essence.
- Improve your odds. Valley upgrades, wisps, fertilizer and the full moon all raise your payout. The Oracle turns Locked YIELD into spendable YIELD.
Why it balances
At a level-0 valley with no bonuses, the expected return from a seed pack is 0.956×. Most packs come back a little short; the occasional Epic or Legendary pull comes back far ahead. The shortfall is burned, which shrinks supply over time. Upgrades and consumables move the average above 1×, so progress is rewarded and idle luck isn't.
