Multiattack

The shadow fey makes two rapier attacks.

Rapier

Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d8 + 2) piercing damage plus 17 (5d6) psychic damage.

Beguiling Whispers (recharge 5-6)

The shadow fey speaks sweet words to a creature she can see within 60 feet, that can hear the enchantress. The creature must succeed on a DC 15 Charisma saving throw or be charmed for 1 minute. While charmed in this way, the creature has disadvantage on Wisdom and Charisma saving throws made to resist spells cast by the enchantress.

Leadership (recharges after a Short or Long Rest)

The enchantress can utter a special command or warning to a creature she can see within 30 feet of her. The creature must not be hostile to the enchantress and it must be able to hear (the command is inaudible to all but the target creature). For 1 minute, the creature adds a d4 to its attack rolls and saving throws. A creature can benefit from only one enchantress's Leadership at a time. This effect ends if the enchantress is incapacitated.
