Pouring arcane power into a weapon or implement, you create a crackling field that lashes at foes with tendrils of lightning.

Daily   ✦     Arcane, Lightning
Minor Action      Melee touch

Target: One weapon or implement

Effect: Until the end of the encounter, any attack that uses the target as a weapon or an implement deals extra lightning damage equal to 5 + your Constitution modifier. As a free action, the target's wielder can end the effect when he or she hits a creature. That creature is then dazed (save ends).
