Forgot to mention you can do this same thing with Cursebrand (swift,battle,occult) and tested with a friend Executioner (Battle, Shadow, Occult) and he had an easier time with the boneyard strategy and the aoe triple slash.
Also, I was 10k GS in the video, but with Immortalist or Cursebrand, with some good practice, you can most likely do this even at 8-9k GS.
