Talion, Ranger of Gondor vs. Dark Soul III

Talion, technically being undead, somehow hears the bell and finds himself waking up in the untended graves outside Firelink Shrine and turns out to be the Ashen One. Can he complete the story? How does he fare? Which ending would he choose?

I'm all rounds, Talion does have limited stamina, but due to his wraith nature it regenerates very quickly.

Round One: Talion alone without Celebrimbor, starts at level one and level only the ranger skills as he progresses.

Round Two: Talion with Celebrimbor, starts at level one but now has access to all of his abilities.

Round Three: Maxed out Talion vs NG+7 Dark Souls III.

If it's a complete sweep for Talion and Celebrimbor, equalize the speed to fit the Dark Souls mechanics and go through the rounds again.
