Lookout tower
Lookout Tower increases the visibility range of your Tower town to a radius of 20 squares.
The effect of Lookout Tower takes place immeadiately after it has been built, and at the beginning of player's every turn after that. This results in a situation where Cover of Darkness can temporarily "darken" its effect by affecting after the tower. In other words, visiting Cover of Darkness on Adventure Map causes fog of war to appear inside the radius of Lookout Tower hiding all movement of enemy hero(es).
