Telepathic Bond. The fiend ignores the range restriction on its telepathy when communicating with a creature it has charmed. The two don't even need to be on the same plane of existence.

Shapechanger. The fiend can use its action to polymorph into a Small or Medium humanoid, or back into its true form. Without wings, the fiend loses its flying speed. Other than its size and speed, its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Sneak Attack. The fiend can deal an additional 5d6 damage to one creature it hits with an attack with its claws or a finesse or ranged weapon, whilst it has advantage on the attack roll. Advantage is not needed if an ally is within 5ft of the creature, or no allies are within 5ft of the fiend. Attacks with disadvantage cannot benefit from Sneak Attack

Evasion. When the fiend is subjected to an effect that allows it to make a DEX saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

Claw (Fiend Form Only). Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) slashing damage.

Dagger. Melee Weapon Attack : +8 to hit, reach 5ft., one target. Hit: 6 (1d4 + 4) piercing damage

Charming Panache. One creature the fiend can see within 60 feet of it must succeed on a DC 17 Wisdom saving throw or be magically charmed for 1 day. The charmed target obeys the fiend's verbal or telepathic commands. If the target suffers any harm or receives a suicidal command, it can repeat the saving throw, ending the effect on a success. If the target successfully saves against the effect, or if the effect on it ends, the target is immune to this fiend's Charm for the next 24 hours.

The fiend can have only one target charmed at a time. If it charms another, the effect on the previous target ends.

Draining Kiss. The fiend kisses a creature charmed by it or a willing creature. The target must make a DC 17 Constitution saving throw against this magic, taking 32 (5d10 + 5) psychic damage on a failed save, or half as much damage on a successful one. The target's hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.

Etherealness. The fiend magically enters the Ethereal Plane from the Material Plane, or vice versa.

Spiteful embrace. as part of a Draining Kiss, the fiend can choose use their bonus action to make a single melee attack with advantage against a target within 5 ft that failed their Draining Kiss saving throw.

Cunning Action. The fiend can take a bonus action on each of its turns to take the Dash, Disengage, or Hide action

Uncanny Dodge. When an attacker that the fiend can see hits it with an attack, the fiend can use its reaction to halve the attack's damage against it.
