I did this run quite awhile back and it's been one of my favourites ever since. Basically, you grab the Parrying Dagger early on and hope for the best.
Rules:
-Your only source of defense must be from parrying.
-No Shields
-No dodging
-No buffs above Magic Weapon except Gold Pine Resin (I allowed this because farming the Giant Mushrooms without dodging is no easy feat)
You may use any weapons you please, as well as any armour and rings. Just remember that you can not dodge nor can you use shields. You have to rely completely on partials in order to beat this.
My build at the time I beat Gwyn
Good luck.
