Fog of War

Fog of war refers to the obscuring effect that takes place on areas of the map that are not within the vision range of your allies. This means that, while you can see the topography of any area on the map, you can only see enemy units located near allied units or your champion. Take note of the areas surrounding your allies. Notice that these areas are brighter. These brighter areas are within the sight range of your champion or one of your allied units. Also notice that the rest of the map is somewhat shrouded. These shaded regions are covered by the fog of war. Enemies in these shaded regions cannot be seen until they enter the sight range of one of your allies. When enemies enter the sight range of an allied unit, they will be revealed, unless they are able to turn invisible or they are hiding within brush.

• Note: There are ways of revealing areas on he map that would normally be shrouded in fog of war. The first is the summoner spell Clairvoyance, which can be placed anywhere on the map to reveal that area for five seconds. Stealthed users are not affected by this spell. The second is to buy consumable Vision or Sight Wards, which place invisible wards on the map that reveal enemy units (vision wards reveal stealthed units) for three minutes. Additionally, certain champion spells, such as Karthus' Wall of Pain or Corki's Phosphorus Bomb will reveal portions of the map shrouded by fog of war.
