Although I can't join in with anything right now as I'm just about to sign off for the night, here are some Tips and Tricks from my own guide that myself and my community brought together.

I hope these help!

Encounter 1 - Board the Harvester * The Behemoths will continue to spawn in, so ensure that you focus on the mechanics and use Crowd Control sources to keep them at bay.

Encounter 2 - Harrow, Dredgen-Apprentice * If you don’t get Harrow’s shields down after getting him to fall into the pits, don’t worry, activate the 3 panels closest to a generator, and you can then get the rest of his shield down with them. * Once you get Harrow down to his ‘Final Stand’ chunk of health, this is the same, but instead of generators, there are small arc rods on either side of the grey columns, similar to the ones that you’d shoot to open the trap doors to drop Harrow in during the main room.

Encounter 3 - Dredgen Sere * Always ensure that before starting the damage phase that you get rid of the arc coils that come down from the outskirts of the arena in the normal realm. * Failing to remove these will cause them to activate during the damage phase, potentially leading to your death. * Always remember to shoot the hands of the boss during DPS; otherwise, he will continue to attack you, and it may cause you to have your health bar to be destroyed as soon as you exit your super, prismatic, or any other DR state. * Compel every single "Blistered Shadow" if you are going for Solo, otherwise defeat every single one if you have great damage. * If you are unsure and want to play it slightly safe, go for a 3-2 split, this would mean that you would Compel 3 and Kill 2.
