Beautify

Beautify is a God Card that unlocks the god power of the same name that cleans up blighted land and improves the natural beauty of any affected land. Cleansing Abodes will also prevent their Followers from catching diseases caused by blighted land.

Acquisition and unlocking
Repair the Shrine of Power located in a clear patch within a swamp northwest of Temple of Battles to acquire the Beautify God Card. The card and power are both unlocked upon acquisition.

Usage
Click on the Beautify icon in the powers menu. You then have eight seconds to apply beautification to as much land as you can by holding down the left mouse button and dragging the mouse across the desired areas. It can also be used to extinguish fires. In the mobile version it costs 400 belief per second to use. It also benefits your buildings by increasing their overall belief production. Use some extra belief laying around to spiff up your buildings and earn more belief.

Duration
Currently, the effect of applying Beautify to you land is permanent, i. e. it will not diminish over time. However, in one of his video interviews, Peter Molyneux stated that this is not the intended behavior, but rather a bug that is meant to be fixed some time in the future.
