You tap into the magic of your failed strike to unleash a mighty barrage of thunder.

Encounter   ✦     Arcane, Implement, Thunder
Free Action      Close blast 3

Trigger: You used a swordmage at-will attack power this turn and did not hit any target with it

Target: Each enemy in the blast

Attack: Intelligence vs. Fortitude

Hit: 2d6 + Intelligence modifier thunder damage, and the target is marked by your swordmage aegis until the end of your next turn. Marking the target in this way does not remove the mark on another target affected by your swordmage aegis.
