Discussion
Scouting is a useful secondary skill early in the game. With it, a hero can quickly reveal undiscovered lands, which may give the player an useful edge when deciding where to venture. However, during the end part of the map when the most important areas are already revealed, scouting becomes somewhat useless. For this reason, scouting is most useful for scout-type secondary heroes combined with traveling skills logistics, pathfinding and navigation.
Scouting radius can also be increased by artifacts speculum and spyglass.
