Mirrored Entourage
Bard Utility 22

You weave a song of illusion, causing duplicates to appear next to your allies. The duplicates try to intercept enemy attacks and disappear when they succeed.

Close burst 20

Target: Each ally in burst

Effect: Each target gains two illusory duplicates of him-or herself that lasts until the end of the encounter. Until the duplicates disappear, the duplicates share the target's space and move with him or her. In addition, the target gains a +4 power bonus to AC. When an attack against AC misses the target, one of that target's duplicates disappears, and the power bonus to AC decreases by 2.

Mirrored Entourage is a daily power available to bards at the 22nd level.[PH2:76]
