it's totally possible guys
I toe-to-toed him in NG+ with no blocking, no dodging/rolling, and no kiting
I had the Mirdan armor set, ring of flame resistance, eternal warrior, adju shield +5 in the off-hand, a Halberd +10, and Water Veil
just healed whenever my HP went below 50%
you can add sticky white stuff or use cursed weapon to the shorten the battle, but its really not necessary
what I did was just strafed to his rear whenever he came close, what for him to do his flame thing (it can't knock you down if you're really close to his rear and with the flame resistance it's no longer that damaging) and attacked straight after
simple, it worked - finished the battle in less than 2 minutes
I was SL 122 at the time
