By the time the Chosen Undead encounters him, Artorias is shown to have already been corrupted by the Abyss with his armor looking putrefied, oozing an aura of darkness. His crippled arm is likely the result of Artorias halting the spread from devouring his wolf companionby means of a now missing shield. He possesses a greatsword that has also been consumed, yet is still far from ineffective. Having lost his sanity, the knight moves about in an untamed, beastly manner as he howls beneath the blue shroud of his helm.
