Usage of Vision is straightforward. It can be used to reveal the location of an enemy town early in the game, or later on to plan out an attack. The effect is fairly useful but limited and is not much of a game changer by itself. Vision also enables the use of many other God Powers, especially offensive ones, or teleportation powers like Shifting Sands, since these powers need to have line of sight to be used. Set players who select Ptah as a minor god for Classical Age can combine Vision with Ptah´s Shifting Sands allowing the player to make a very efficient rush, though the player must find first the enemy Town Center to do this. In team games, Vision enables players to use offensive powers, such as Meteor or Tornado, directly in the core of the enemies towns without launching a full-scale attack.
- On Random Maps, if the enemy AI worships Set, it will always cast Vision at the beginning of the game exactly above the Town Center of the player or of one of their allies'.
