Taken thralls, taken phalanx, I think a taken legionnaire spawns too. The way we did it, 2 guys are on a middle platform where the daughters are in the previous part while the rest of us are on the platforms we have to be on. We were told not to shoot at the ogres at all, the guys above sniped them down to low health. I took out all of the adds that spawn up to that point. We jump up to higher platform to dps Oryx. When he flinches we run (all the way to the front where Oryx spawns or the back at the entrance) to detonate our bombs. This is when there's another add spawn. They spawn close to where the ogres wander to if you do the no Knights. 4 are detonating bombs, 2 are helping clear out the latest wave of adds. One clears adds in the front area, the other in the rear. Since there are so many spawning so close you're likely to lose someone at each bomb wave. This works best if all 4 bomb detonators are sun-singers. The two who stay at the top platform run as a defender and a nightstalker. They have to focus on clearing the adds away from the sunsinger who just died and doesn't have his super up yet. This is so complicated... Just kill the ogres and the Knights and get it over with!
