Calming fog

You exhale a fog of smoke in a 20 ft area around you. Any creatures of your choice, within range, must make a charisma saving throw or be charmed for 1 minute. During this time they will do as you ask. Should you ask them to harm themselves or 1 of their allies they will make another saving throw with advantage. Should they succeed they snap out of it. If they fail they must follow through with the action which will immediately end the spell afterwards.
