SPELL AREA. A tower, shaped as a square, a hexagon, or usually a circle, is a series of limited closed spaces, stacked upon themselves. Any area spell a wizard casts, centered on himself, will probably cover an entire floor. Making the structure easy to defend. Besides, consider the scenario: attackers in the low floor, wizard can see them by a hole in the ceiling. Through the same hole, the wizard can cast a cone area spell that will hit everyone in the floor below. This spell may not kill the entire party, but the wizard can rinse and repeat, going up the tower, wearing down the attackers, until he wins. And that is just one strategy the wizard can use. So, in towers, ONE wizard, can stop an army.
