I am stuck on the ceph mastermind while trying to beat it on Soldier difficulty. The thing is I watch the videos on youtube and read about how to fight it. Thing is though I don't want to turn down the difficulty, but could someone tell me it's weakness. The furthest i've got was when the mastermind released the minions and they all flooded toward me. I could sometimes take them all down, but then it's just the boss and me. When that happens, that is when he goes crazy and kills me while regenerating his dead ceph to his side in the air. Yes I also use armor mode as well. So could someone please help me to get through this part? Possibly on Soldier difficulty?
