The video is not demonstrating the build, no aura of holy might and there is a bonder.
Maybe you could make a video that does actually demonstrate the build pls ?
In his article he mentioned using Radiation field opposed to aura of holy might. -6 degen + 20 seconds of disease > +5 damage, with SF maxing your damage at 26.
I'm sure it can be done in NM without a bonder, but in HM the grasps just take you out to quick.
