ive watched this video with surprise and weird feeling.
(trash mob so fast, but little wired ...)

and found using permanent insanity (so not cause severe exhaustion)
but... is it possible to permanent insanity like this ?
(about 70sec duration / about 30sec cooldown on this video)

ive considered with poor brain, but couldnt find.
