Snake,

I feel your pain on this. Currently running 4 characters through this event. My two twinks need 5 mins and 10 mins to finish this boss or Ursoth. My lvl 41 and 39 need between 5-20 mins depending on the party. Overall I need around 2 hours a day to use my STS given energy. These bosses are tougher and take longer to kill than tindrin elite bosses.
