DT slithering chaos build

Is there any kind Dt who could share with me a proper build for that dungeon? Yesterday I tried my best and I couldnt tank the boss during the 3rd phase. I am full t4 geared, 2rf rings with gems. Maybe healers were not doing their job as they were dying a lot at the 1st and 2nd phase.

I am tanking using shield, not a tali spec

Just use a classic CoI prot spec.

If I remember correctly that boss requires two tanks to trade off aggro because of how hard he hits in that phase. Unless they changed the mechanics or I’m thinking of something else.

You’re thinking of sepulcher.
