His role in Pathfinder is one of a tank: high AC, but low damage output.
In 5e, he is more of a utility character that can fulfill a variety of roles in the party.
His shield has a hand-painted symbol of the Many-Headed Serpent, his deity. It is a non-human deity that lives at the bottom of every waterway, like a hydra... I liked the imagery. The MHS is either N or CE, depending on which aspect his followers favor.
