The "Scouting" spell could work like this: it is automatically added to the spellbook when the Scouting skill is learned, granting +1 to the sight radius for 10 mana – this can be used a certain number of times, with a maximum sight radius equal to that of the standard Scouting spell, achieved at the third level of the skill. The hero can use it once per day on the adventure map.
