To rebuild the Island, players must de-curse the Island, its residents, and other items. During Deep Dives, players will also need to de-curse underwater areas and creatures.
Drag magic onto a cursed area, Islander, or item to de-curse it. De-curse buildings by clicking on the structure and dragging the pickaxe across it.
Some items or areas cannot be de-cursed until you've reached a specific level. If a cursed area requires more magic than you have, you'll need to increase your magical limit to de-curse it.
