Fiendish Charm: One humanoid the cambion can see within 30 feet of it must succeed on a DC 16 Wisdom saving throw or be magically charmed for 1 day. The charmed target obeys the cambion's spoken commands. If the target suffers any harm from the cambion or another creature or receives a suicidal command from the cambion, the target can repeat the saving throw, ending the effect on itself on a success. If a target's saving throw is successful, or if the effect ends for it, the creature is immune to the cambion's Fiendish Charm for the next 24 hours.
