3/day each: alter self, command, detect magic

Multiattack. The cambion makes three melee attacks: two with its Warhammer and one with its Sting; or uses its Fire Ray twice.

Warhammer. Melee Weapon Attack: +7 to hit, reach 5 ft., one target.Hit: 13 (2d8 + 4) bludgeoning damage, or 16 (2d10 + 5) bludgeoning damage if used with two hands, plus 3 (1d6) fire damage.

Sting. Melee Weapon Attack: +7 to hit, reach 10 ft., one creature. Hit: 9 (2d4 + 4) piercing damage. The target must succeed on a DC 15 Constitution saving throw, taking 16 (3d10) poison damage on a failed save, or half as much damage on a successful one.

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

Fiendish Charm. One humanoid the cambion can see within 30 feet Of it must succeed on a DC 14 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.

Weighted Net. Ranged Weapon Attack: +7 to hit, ranged 20/60 ft., one Small or Medium creature. Hit: The target is restrained until it escapes the net. Any creature can use its action to make a DC 15 Strength check to free itself or another creature in the net, ending the effect on a success. Dealing 10 slashing damage to the net (AC 12) destroys the net and frees the target.
