I wanna feel like a ninja

I want to play a legend that makes me feel like a ninja, like imagine you can walk on top of narrow walls easier without falling off, you could have like silent step, or run slightly faster, this character could have like a roll or evade type ability, and something ninja like. I know this wont actually be added into the game but wishful thinking i guess, but feeling like an assassin or ninja or any stealth like person would be so fun to me and im sure a lot of others.
