When activated, this power took the defensive Force powers a Jedi was most skilled in, pushing them to the highest degree that the Jedi had previously mastered during his or her routine training. The affected powers that the Jedi Exile used to enlight were Force speed, Force Defend (Force Armor or Force Shield), and Force Valor. The end result was an "enlightened" Jedi, having unlocked and harnessed fully the light side of the Force.
i also believe this power is very useful considering that is helps you to unlock the full lightside of the force thus making the jedi just powerful enough to defeat his enemy, without killing him.
