Once a building or wall has been de-cursed, players must finish restoring them. Restoring buildings and other structures will increase your Magic Limit.
Select a de-cursed building and drag bricks into the highlighted spots. If you run out of bricks, you can obtain more from the Mine.
Once all the bricks have been restored to a building, you can also upgrade the chimney, windows, and door. If an upgrade is grayed out, you're not a high enough level to use it. You can click on the grayed out upgrade to see what is required to unlock it.
Repairing other structures
Walls, fences, streetlamps, and arches can also be restored. To repair the stone border at the top of a wall, select the damaged stone and then drag the new stone into position. Fences, streetlamps, and arches can be repaired the same way.
