Target: One creature

Effect: The target takes 20 + your Constitution modifier psychic damage. You then assume the aspect of luminous thought until the end of the encounter. While in this aspect, you can use the following augmentation with your battlemind at-will attack powers that are augmentable. This augmentation is in addition to the effects that an at-will power might have; this augmentation doesn't supersede them.

Augment 2

Effect: Until the end of your next turn, you gain a +2 bonus to all defenses against the targets of the at-will attack. In addition, choose a single creature hit by the at-will attack. That creature takes extra damage equal to your Wisdom modifier.
