Use him early to do campaign mode, upgrading him to 71. He can be used until you get a better shooter to replace him.
You should reset him back to 1. Unfortunately, he isn’t a useful hero, provides no passive skills, and there are better shooters to use in a troop formation.
He can be obtained in Noah’s Tavern.
