The Spirit has advantage on attack rolls against creatures that are frightened of it.
When the Spirit makes an ability check or saving throw you can use your reaction to expend a use of Bardic Inspiration and add it to its roll.
One creature of your choice within 30 feet of the Spirit that can hear it must succeed on a Wisdom saving throw or be frightened of it for 1 minute. It can repeat the saving throw at the end of each of its turns, ending the effect on a success.
Melee Spell Attack: your spell attack modifier to hit, reach 5 ft., one target. Hit: 1d8 + your Charisma modifier necrotic damage.
