I use a freezing stone in my talon ( Stinging Cold IV -200 Evasion) helps a little. I'd recommend a high level conjuror join your hunts, and perfect spell -> Stinging Cold V on him every 2 min (soon as it recycles). Or even better, an ICE spell with numbing V tech on it. reduces his evasion (somewhere around 2000 it seems) by 25%.
That, and using ethereal attacks ( misty stones) and you can whittle him down.
