Fiendish Blessing. The AC of the cambion includes its Charisma bonus.

Innate Spellcasting. The cambion’s spellcasting ability is Charisma (spell save DC 14). The cambion can innately cast the following spells, requiring no material components:

3/day each: command, detect magic, hold person

1/day: teleport (self only)

Multiattack. The cambion makes two melee attacks or uses its Fire Ray twice.

Longsword. Melee Weapon Attack: +7 to hit, reach 5 ft. or range 20/60 ft., one target. Hit: 9 (1d8 + 4) piercing damage, or 10 (1d10 + 4) piercing damage if used with two hands to make a melee attack, plus 3 (1d6) fire damage.

Fire Ray. Ranged Spell Attack: +7 to hit, range 120 ft., one target. Hit: 10 (3d6) fire damage.

Change Shape. The cambion magically polymorphs into a humanoid that has a challenge rating no higher than its own, or back into its true form. It reverts to its true form if it dies. Any equipment it is wearing or carrying is absorbed or borne by the new form (the cambion's choice).

In a new form, the cambion retains its alignment, hit points, Hit Dice, ability to speak, proficiencies, and Intelligence, Wisdom, and Charisma scores, as well as this action. Its statistics and capabilities are otherwise replaced by those of the new form, except any class features or legendary actions of that form.

Incite Fervor. One humanoid the cambion can see within 30 feet of it must succeed on a DC 14 Wisdom saving throw or be magically driven to rage for 1 minute. The target gains immunity to the charmed and frightened conditions. The target must move up to its full movement speed toward a creature on its turn and use its action only to make melee weapon attacks. If the target ends its turn without attacking a creature, it immediately takes 1d12 psychic damage and 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 Incite Fervor for the next 24 hours.
