What build are you using? I think i just lobbed rocks at him and he died quickly with my mage build. Greatblade phalanx works pretty good against him too.
Kind of a strength/bleed build. I was mostly just leveling strength/endurance/vigor. Then when I got the bloodhound fang I maxed it out and have been labeling up dexterity (& occasionally arcane).
Yup. My bad. I was levelling up arcane as I was considering a swap to a bleed build with dual katanas, but after trying it I realised I preferred two-handing the fang.
