The challenge has a timer, must be 12 min but the normal t2, without lighting brazier, doesn't. At least up to 20+ min, I checked it this morning. Each wave, whether its adds or bosses, arrives at 1min intervals, unless you kill them earlier, which triggers the next wave. Probably not possible with regular buffs, some of those bosses have a lot of morale. Interesting thing is wardens probably can't do this either. I've seen them last a long time but stuns from bats and fire pools would probably kill them eventually. However, fully buffed, it might be possible by a champ, since our aoe can kill so many adds. Worth trying at least.

Would be interesting to know how wardens have done with this challenge, maybe OB1 knows.
