Fog of War

The Fog of War is the effect that takes place on areas of the map that are not within the vision range of an allied champion, minion, or ward. This means that, while player can see the topography of any area on the map, they cannot see enemy or neutral units that are in the Fog of War.

Areas which are not obscured by the Fog of War are brighter on the map.
