Depending on your 2ndary profession, if you are E/Me, then you can smile.
Use domination magic to you advantage. Make him use 3 of his interupts and then cast Empathy. Use Cry of Frustration to stop Troll Unguent. Some health degen would be nice too.
You can also go full Ele and use:
Swirling Aura (Water)
Blured Vision (Water)
Or
Stone Daggers (Earth)
Sliver Armor (Earth)
Obsidean Flame (Earth)
Glyph of Energy (e)
Kinetic Armor (Earth)
Crystal Wave (Earth)
Teinai's Crystal (Earth)
You can always try for a knockdown - Enervation + Stoning + Aftershock/Ash Blast. Or Whirlwind + Aftershock/Ash Blast or use Shock + ...
Always take Glyph of Concentration
Hope this helps.
