I killed him easy with my lvl 14 warrior using sword and shield with 360 hp.
Just rush in and use a lot of jump attacks when he puts a fear spell on you use it in your advantage and run a little and rush back in with your rush attack and jump attack egain i only used 2 potions thad give me 150 hp and use a pet and ghost they are verry handy in this fight.
If you are a warrior and have some more questions about killing him just ask.
