Raszageth Thunderous Blast DH Tank mitigation

In tanking the Ras on the last phase the ability: Thunderous Blast seems to be a bit of an issue for me as a Demon Hunter tank. I am wondering how best to mitigate the damage from this ability to avoid massive damage to the raid(esp. in larger groups). Any suggestions would be great.

Externals.

Pain Supression for example.

lmao.

How depressing

Thats what I was wondering do I have to rely on other players or is there other things I can do, ie specific trinkets.

I’m afraid I’m not well versed in defensive trinkets.

Offense is the best defense.

lmao.
