Does this mean a flight only character can only attack back row to back? I.e. A flight character can not attack from back row to enemies front row?
A character with flight and not ranged can only attack FROM THE FRONT ROW to the opponents FRONT OR BACK ROW.
A character with ranged and not flight can attack FROM THE FRONT OR BACK ROW to the opponents FRONT ROW only.
A character with both ranged and flight can attack FROM THE FRONT OR BACK ROW to the opponents FRONT OR BACK ROW.
In all cases, if the opponent has a character with flight IN THE FRONT ROW, you cannot attack a character in their BACK ROW.
