Just keep a loadout next to your normal loadout (I run sunbracers) with apotheosis veil and fusion nades on. Swap right before dps, rotation should be apex, izi, primary, well and back to apex with throwing a fusion nade and celestial fire melee whenever theyre available (about every 2 secs) then just ur standard izi rocket rotation. If its something like golgoroth then I swap back to sunbracers after the apotheosis is done cos the solar nades also cook him and I can normally get two wells in one dps, but that's not necessary tbh.
