The picture was supposed to represent the reflection of his morality, yes it does keep him young(far from immortal, many hints in the novel states that he can still be killed if he is shot by a gun), it is NOT a magical artifact that makes him invincible.

The youth it gives him is for the sake of allowing him to live his life endlessly in his prime, what he believes to be the happiest days in the life of a man. Dorian exploits this point to indulge in worldly pleasure, most of which are immoral(which basically means his personality will break down within 5 minutes when he learns that he is in a battle royale to the death which he has zero chance of winning).

The portrait reflects Dorian's indulgence in immorality by growing uglier and more monstrous the lower Dorian reaches. Unless you are going to include this symbolism, you have completely missed the point of the story.

Which again bring us back to the point that he is not a fighter, Dorian in the novel evades physical confrontations on more than one occasion because he know he will be beaten up. In case you need me to repeat that: He will pussy out at the sight of a guy 10cm taller than him, what made you think he will be willing, much less able to fight a hero holding a sword?

If you STILL don't understant, I will say this, Dorian makes as much of a Servant as godfriggin Pinocchio would.

EDIT : And god how many times do I have to tell you triple posting is obnoxious?
