This video shows how I defeated Ornstein & Smough (Super Ornstein) during my Sorcerer playthrough. Swap your Ascended Pyromancy Flame+5 with your Longsword+5 for this fight, both enemies are weak to Fire and to avoid damage you will want to use ranged Sorceries. Your main focus for this fight is to kill the fat one, Smough. Summon Solaire and wait for him to spawn in. If you run away immediately he falls for some reason and takes unnecessary damage. Once he spawns in, head to the fog gate and enter to begin the boss fight. Ornstein will fly across the room and attack you immediately as the fight begins. Have your shield up to tank the attack and try to move away from him so he focuses on Solaire. This is your cue to attack Smough with Great Combustion. His attacks are easy to telegraph and if you stay close to his body with your shield up, attack him in between his own attacks. Try to get this done as soon as possible to ensure Solaire doesn't lose too much health to Ornstein. There will be a cutscene once you have killed Smough, leaving Ornstein to become super-sized. The remainder of the fight should be at range with Sorceries. The trick to finishing off is swapping aggro between yourself and Solaire. Watch out for the following attacks: Ornstein can shoot lightning at you with his spear. There are two variants of this attack and this will usually occur at range. You must roll to dodge this attack as your shield won't block the damage. He can also jump up in the air and slam down on the ground, dealing Lightning Damage in a close proximity. If you see him jump in the air sitting, he will do this attack. You must roll away to avoid damage. Ornstein can sweep his spear from either side of his body. You will be able to tank this attack with your shield or you can roll through the attack. He can also swing the spear vertically down, so roll to either side. Similar to his flying spear attack when you entered the boss area, he can do this same attack, but with more damage. You will be able to tank the damage with your shield, or roll to the right to avoid damage. He has one final attack where he pulls the spear to the side of his body and it sparks. He will drive the spear into either you or Solaire and lift you off the ground with it, causing an electrical explosion. This deals massive damage, so you must roll away from this attack at the right moment.
