After a few tears, I finally figured how slay the damned beast! The first important thing to note is that during my first play through I had no trouble fighting the winged fiend! The trouble is in NG+. Though my character is soul 130, with 40 vitality, strength and endurance, the dammn monster could still one shot me. I can understand being one shotted with one specific attack with no shield, but with the shield up, and often times full stamina, it was a bit ridiculous. More than anything it was the inconsistancy of the one shot fire breath that pissed me off more than anything, sometimes I would die, sometimes I wouldn't. Anyway, I ended up using magic to kill the basstard. By using the Oolacile Ivory Catalyst, the Crown of Dusk, and dark bead, I was able to kill him by using all six of my magic castings. I ran up the stairs, out and around to the side of the bridge, (the part where his first fire attack can't get you) and let him kill the hollows. Then I would stand real close to the edge of the safe zone to trigger him and make him come down. Then as he came down, he would land and do a breath attack. THAN I ANNIHILATED THE BASSTARD!!!!! Just make sure that he is going to shoot out his normal fire spray and not fly up in the air, if he flies, use the black knight shield and try to block some of the damage.
