Solo 1 Phase Hefnd's Vengeance on Hunter ( No Trials GL )

One phasing this boss on hunter without the trials gl was hard until me and my friends thought about using regnant with one for all. It does at par damage with bait and switch and is pretty situational. Also, one of the best if not the best grenade launcher in the entire game which is cataphract getting locked behind trials is pretty lame and I cba to farm it let alone get the god roll of that grenade launcher.
Thanks to @tarangjain6 for telling me to use one for all on this boss.
Enjoy!
