|Zoltun Kulle after you're|
finished with him ;)
The video below shows you how to do the initial rinse/repeat of starting the run and getting the XP. The one thing I happened to discover in my initially fighting is that if you immediately run opposite of Zoltun and stand in the little area where the energy floor appears after the fight, he'll stay opposite you in the other floor area, along with his minions. Then you can just toss some ranged attacks at him and he'll just sit and take it. No running, no dying, etc.
Occasionally you might get a whirl wind attack coming your way but as long as you can withstand a quick pass through the tornado will keep going on and away from you. Check out my video below:
