How it works
- Water Essence is the island currency. The Fountain of Life produces it every hour and holds up to 12 hours of output, and the Reservoir extracts it from the Cacti covering the island.
- Decorations are bought with Water Essence in the Island Shop or won in events. The shop refreshes every 7 days.
- Decorations only count once they are placed on the island.
- Each decoration has a Type Limit: only that many placed copies of it count, highest level first. A Type Limit of 0 means it gives no bonus or Prosperity.
- Only the current level’s bonus counts, once for each copy within the Type Limit.
- Upgrading uses unplaced Lv. 1 copies from the Island Storehouse. Dismantling an upgraded decoration returns the Lv. 1 copies used.
- From Fountain of Life Lv. 3, allies can help maintain your Fountain once every 6 hours, up to 3 times a day, for Water Essence. The daily count resets at 00:00 UTC.
- Island Wonders give their bonus as soon as you own them, whether or not they are on display.
Overview
Oasis Island is a personal island you build up with decorations. The Fountain of Life and placed decorations give stat bonuses such as troop attack, healing speed and gathering speed, and decorations also add Prosperity, which the Fountain of Life needs to level up.
