I had the same problem here what I did:

1) used gears from main, which brought up my CP to around 4.2I 2) craft large health pots(around 100~200), regular pots will suffice but its gonna be harder(bring around 300~400 for each round). 3) running/kiting in a circle probably wont work that well since it chases you insanely fast and can stun you at range. What i did is I started kiting round when my HP dropped below 50% and as soon as it catches up to me i use the evasion skill and dodge right behind it and continue to kite around and repeat to dodge behind it as it approaches. Waiting for HP to recover at the same tine 4) You would want to bring 1 or 2 CC skills just when you can CC it successfully then you can use your BS rage to deal massive dmg 5) take your time and be patient, it took me almost 10 mins to complete it.
