Reminds me of the 3.5 monk with some vow of non-violence or something. He thought he could go defensive and attract enemy attacks with his silly-high AC, but they just ignored him and walked by. If he attacked them, lots of his abilities collapsed, so he just danced around doing nothing while everyone else got killed.
If I wanted to do that in 5e, I'd go Long Death. "Fear. Fear. Fear. Still want to keep going?"
