How it works
- The Fountain of Life holds up to 12 hours of Water Essence, so collect it at least that often.
- The Reservoir extracts Water Essence from the Cacti that cover the island, and Reservoir workers collect it at the Purifier.
- From Lv. 3, allies can help maintain the Fountain once every 6 hours, up to 3 times a day, for Water Essence.
- Higher Fountain levels unlock more decorations in the Island Shop.
- The Fountain of Life and Reservoir cannot be dismantled.
Overview
Each Fountain of Life level adds a new bonus, and the bonuses from every level stack. An upgrade needs Water Essence and a total island Prosperity, which comes from placed decorations.

Collection and Prosperity
- The Fountain stops accumulating after 12 hours of output. A 24-hour figure assumes you collect often enough to avoid the cap.
- Prosperity is an eligibility threshold, not a currency spent on the upgrade. Decorations must be placed and within their Type Limit to contribute.
- The Fountain's level bonuses stack. Ordinary decoration bonuses use only the active copy's current level.
