[AreaOfEffect]

Let me see if I'm understanding the situation correctly. You want a commander to lead an army 2 (possibly 3) provinces away. However the commanders movement is more limited then the troops he would be leading... who walk and can't fly. So either the commander has a normal move of 1 (possibly 2) or he lacks some survival ability that all of the troops have. So you've decided to equip winged shoes (possibly flying carpet) and the army still can't move the 2 or 3 provinces needed?

-Are you sure the army can make the distance on their own with a move 2 commander with similar survival abilities?

-Are you sure the commander, with the additional flying ability, can still make the distance? The global spell "Perpetual Storm" limits the movement of fliers.
