In my opinion, this mini-boss is best handled in close range, though things like the knife and chakram can help too. Full details at: /?id=213943327#209504
Note: This video was recorded on New Game Plus 2 with one Grace Rune to reduce difficulty somewhat. Still, the principles used in this fight remain the same regardless of your level and progress through the game. (And yes, I am playing as the Traitor class after all the Obol bosses, though I don't use the multi-knife or multi-axes as part of the strategy here.)
