It's on now. Get a high score to begin with. We went for arc, extinguish, match game, and blackout, and a power handicap of 60 as all 600. You do not need a void weapon as there are no void shields during this strike. You will need at least one arc for knights and solar for wizards. We managed to clear 260 for this strike. Once you have your high score just start re-running it doing whatever burn you want and heavyweight only. With blackout and arc the thrall can menaces in that final room but it is highly doable. Thunder lord melts everything. I managed to get the rocket launcher on my 11th run. Tip for quick boss melt: Have one radiance warlock arc burn heavyweight and three wardcliff coils. As soon as nokris becomes susceptible to damage continuously fire the wardcliff until dead.
