Round 1: Keksis - None of these are easy but the fact he keeps taking away your abilities is rather annoying. If you have Monte Carlo its a great time to use it. Any armor that gives you another Melee attack is helpful as well. His main attack is the flying black ball of blinding death. Avoid that when at all possible. Also on the right side of the map from when you enter will be a few Solar snipers, try to target those early on so you don't have to worry about them. The other ability Keksis has is a Light draining bomb. If you can stand in it you can channel it to go away but typically Keksis is near by. not worth the risk of dying but if you can go for it you should. Other than that its rinse and repeat on enemies.
Second part is Val Aru'un. I tend to have a high impact sniper for the bosses, and here the flayers. Main key here is to take out the Phalanx first and then the Psions. Once the adds are down take out each of the Flayers once their shield type is chosen. After all the Flayers are down then just dmg the boss and take out the adds in the waves they come. Toughest part is the start.
Finally the Seditious Mind. Easiest of the 3 rounds by far. Main thing he does besides fire at you is put a red ring on the ground that you don't want to stand in since it hurt you. That red ring has a blight bomb that will detonate after sometime. That could be lethal after taking damage from the ring so try and avoid that at all costs. Other than that a few Hobgoblins are tough to Melee but the Goblins aren't too bad. Stay in cover and you should be okay.
