49 minutes with ONLY two Defenders, Cold/Dark, Kinetics/Psionics, 54x8, no inspirations, NO DEATHS - ITF.

[Voltak]

Cold/Dark Defender using/abusing powerboost, along with a kinetics with unresistable damage in the Imperious Task Force. No deaths were allowedv-- 49 mins, rivaling blasters. 

I go over the benefits of power boost in the video. 

Note:  I have both in my build, Barrier and Clarion Radial.  

For this run, Barrier, but Clarion is equally as good, maybe even better.
