Swordmage's Decree
Swordmage Utility 6
Speaking ancient words of aegis binding, you lower a mantle of magic over your enemies that marks them as your foes.
Close blast 3
Target: Each enemy in blast.
Effect: The target is marked by your Swordmage Aegis power. Marking the target does not remove the mark on another target already affected by your Swordmage Aegis. If you mark only one target with this power, you do not expend the power but cannot use it again during this encounter.
Swordmage's Decree is a daily power available to swordmages at 6th level.[AP:55]
