Clause

You choose a creature you can see within range and state a single rule, no more than 25 words in length. The creature must succeed on a Wisdom saving throw or feel compelled to follow this rule. Each time it attempts to break the rule, it must make another Wisdom saving throw. On a failed save, it takes 3d6 necrotic damage and must continue following the rule. On a successful save, the spell ends early, and the creature can proceed with its intended action. The rule cannot compel the creature to take obviously harmful actions toward itself.
