Currently running 4 piece Exodus . Breath (Unstoppable) and then directly to my Ringing Nail with incandescent and Burning l Ambition to further increase my ignitions. Ringing Nail is also key as you will have barrier servitors lingering around shielding everyone. Focus on the overloads first then the servitors. When you drop it's barrier I recommend focusing on the adds as they are required with wire rifles that will do short work of you. I'm using Dawn Chorus for increased scorch DMG and stronger ignitions as well as getting more melee energy back. Phoenix Dri ve is also a must in my opinion. You'll breeze through this rather annoying lost sector.
