Today was the daily for VH. My first boss was Xevozz. He kept teleporting my group and killing us. So I did some research and found a good tactic to beat him. You should never get teleported using this. By the time he summons a second set of balls he should be close to dead. I found this on youtube ----

I did that tactic and it was cake.
