The clearing loop
Place Reservoirs so their workers can reach the cacti. Collect their Water Essence and upgrade the Reservoirs to improve the workforce. As the island opens, clear the cacti surrounding visible Island Treasure Chests, then open the accessible chest. The island can continue producing Water Essence after the final cactus is cleared.
Clearing milestones
| Stage | What to do |
|---|---|
| New island | Place Reservoirs and follow the island tasks |
| Reservoir level 4 | Two workers become available per Reservoir |
| Visible treasure | Clear the surrounding cacti and keep a route open |
| Reservoir output waiting | Collect it before the building stops storing more |
| All cacti cleared | Unlock the Purifier and keep Reservoir workers active |
Finding and opening treasure
- Use the Island Treasure control to locate treasure that the island currently exposes.
- A visible chest may still need the surrounding cacti removed before you can reach it.
- Prioritise a useful clearing route to treasure rather than sealing the worker path with decoration.
- Inspect the selected chest for its rewards. The decoration catalogue does not establish a universal chest order or reward amount.
- When no treasure is found, continue opening the island rather than assuming the chest reward has already been claimed.
After clearing the island
- The Purifier unlocks when all the cacti are cleared.
- Reservoir workers can extract Water Essence at the Purifier.
- Your Fountain continues producing independently; clear collection routines still matter after the exploration phase.
- Decoration upgrades, Prosperity and Island Wonders continue after the clearing objective is complete.
