I Beat Dark Souls as a Painting Guardian

In this challenge run, I became a Painting Guardian in Dark Souls. Using only the Painting Guardian armor and weapon, I set out to defeat every major threat in Lordran — while refusing to kill Priscilla and protecting the Painted World of Ariamis. Fast rolls only, assassin-style combat, and no heavy weapons. If anything threatened the painting, it was dealt with. After defeating every enemy, I returned to my post… and guarded the painting once more. Let me know which Dark Souls roleplay or challenge run I should try next.
