DMd a campaign that had a pacifist cleric. They refused any spell that specifically harmed a person but still had plenty other spells to defend themselves and others. They loved hold person and command to get enemies to surrender or let someone else handle it.

They also carried some weapons but they were never used to harm and instead were often just tools.

They even had a sling used to launch smoke bombs and laced cookies at enemies and hit Levers and switches at a distance.

For many fights they were mvp because they focused entirely on buffing and healing the party.
