Water Essence and Prosperity
Water Essence is spent on island upgrades and purchases. Prosperity is a separate placement-based threshold for Fountain upgrades; it is not deducted like a currency. Check both before planning the next Fountain level.
Where to collect it
- Claim the Fountain of Life regularly: it stores at most 12 hours of production.
- Collect the Reservoir while workers clear cacti; keep a route open between Reservoirs and their work.
- Open island treasure chests and complete island tasks.
- Help allies: each help awards 200 × Water Essence. You can help 3 times daily.
- After all cacti are cleared, Reservoir workers can collect through the Purifier.
