Really appreciate the tips Xago. I also did not know the mechanic for the teleport. I thought it was distance based, but looking back I was kiting around the crystals in the middle. Perhaps I will work on Act 4 tonight.
It's a really easy (but long) fight once you learn to keep him from teleporting assuming that you have enough dps to kill the images in P2 (wasn't a problem for me). Use the hex +20% damage rune and the + damage rune on mass confusion too. They die so quickly then.
I have 62k damage, 25k hp, and 23% movement speed. However, I am only just past Iskatu in Act 4 meaning I have to make it past Rakanoth and Izual before I get to try this.
