Trigger Doomshare do the Masters still chant?

[Kidas52]

I was just wondering if the masters still chant when Doomshade is triggerable. The first and last time i killed him i didnt notice anything different from what the masters are doing now. I am trying to get my ranger the bow of doom and I could use the speed earing to get a more defensive belt.

So just wondering If i just wait 3 or so days after i kill him each time without any indication of wether or not He triggerable or should I wait in zone for a set amount of time waiting for the chant.
