Boss Group Pathing[]
It is important to take notice of the boss's patrol route for this as you will be comboing at either end of the route.
When you enter the area the boss group will likely be walking from western side of the camp towards the middle-ish. From the middle, the group will then patrol back and forth between there and the southern end near the prison cages.
You will be comboing at the end of this patrol on either end when the group balls up for a few seconds.
Nuking[]
