Castlevania Lords of Shadows The Forgotten One (Paladin mode) no cheats, no damage plus Full Ending

As far as I know the forgotten one is definitely the most difficult boss fight in all of castlevania. So I gave myself a challenge, I finished it on Paladin mode, no cheats, no items, no light and shadow magic and I took no damage. took me almost an hour to defeat him on full health by just using regular attacks with the vampire killer.
