Ready inner beast right before the huge Double AoE, also pop vengeance, if needed also Battle thrill and you shlould be completly safe from dieing. If vengeance isnt ready use Holmgang for it, but tell your whm so he can benediction you when you drop to 1 hp. its all a timing thing. I had issues at the beginning as well, now its just cup cake once i got used to the timing(sorry for bad english)
