Shadow Spirit

The spirit has advantage on attack rolls against frightened creatures.

Any creature, other than you, that starts its turn within 5 feet of the spirit has its speed reduced by 20 feet until the start of that creature's next turn.

The spirit makes a number of attacks equal to half this spell's level (rounded down).

Melee Weapon Attack: your spell attack modifier to hit, reach 5 ft., one target. Hit: 1d12 + 3 + summonSpellLevel cold damage.

The spirit screams. Each creature within 30 feet of it must succeed on a Wisdom saving throw against your spell save DC or be frightened for 1 minute. The frightened creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

While in dim light or darkness, the spirit takes the Hide action.
