Sorry for the vague title, character limit you see :/
I'm playing a character that is bound to level 1 forever and doesn't use any skills that can be leveled. Instead I make use of greater powers, fists, lycantrophy, shouting, cooking... it's good fun.
Now this 100 health absorb nightingale power is something I'd go through the whole questline for. Can I punch my way through the questline, maybe with some help of the tower stone for picking locks?
