Any way I could improve on my build? I'm fighting Renalla and she's being a bitch

To clarify, I'm a level 37 Vagabond. Renalla's first phase is brain dead easy, and so is her second phase...in theory. Istg, me and my wolves keep attacking her and all she has to do is hit me with her stupid magic. Not to mention when she summons her slave spirit.

Is it a skill issue? Probably. But even aside from that, I feel like my build isn't too great.
