Ludwig, the Holy Blade Boss Fight

Sorry for the lack of audio, there was far too much clipping for me to comfortably upload it. I'll re-upload with a new video once I get a decent recording. This boss has two forms and are noticeable changes and you'll know when it happens, due to a cutscene. You're able to get two NPCs to help you, and they'll prove invaluable to you. As they provide distraction. Keep to his right side (your left) and just keep having at him. Character level is 96. This is NG +0. Weapon used was the Saw Cleaver +10 buffed with fire and bolt.
