Master Vule

The Fight

Master Vule is rooted to his location. He is slowable.

Strategy:

Have group off to the side away from Line of Sight of Vule (can move in and out to dot/dps).
At every 5% starting at 94%, adds will spawn that need to die throughout the fight or they increase Vule's power.
The add comes from specific spots around the circular room. Once they all have been killed and Vule is at 34%, your group will be teleported to a location you must not leave. If you move, you take heavy damage (including pets). Use all ranged dps possible to nuke Vule during this phase.
He will need to be stake spammed (with the Vampire Bane Earring from DSK1) by everyone in your group. If your group can stake him enough times, he will die. Make sure your entire group is spamming the earring until he dies.
