There is a way to break the event, and make it even harder. If you kill the first set of two adds he pops when he feigns death, he'll immediately pop a new set of adds when they die, then he'll start regenerating HP. Ever feign death afterward, he'll regenerate his HP back to 100%. Luckily he only spawned the same number of add waves (whew!).
Smacked myself on the forehead after realizing the mistake I just made (been a while since I stepped foot in the zone and couldn't fully remember the mechanics of the event).
Fun event!
