Crow of Judgement

Keen Sight. The Crow of Judgement has advantage on Wisdom (Perception) checks that rely on sight.

Precise Condemnation. The Crow of Judgement has advantage on Insight and Investigation checks against it's Target for Judgement.

Unruly Familiar. The Crow of Judgement will oppose all attack or disengage commands, magical or otherwise, including orders given by any non-demonic allies or masters.
A creature must succeed in an opposed persuasion check, against the the Crow of Judgement, in order to give it new attack commands, disengage it from a attacking, or to shoo it away. If a creature fails the check, the Crow of Judgement will continue its current course of action, unaffected.
No persuasion is required if the command is to cast non-offensive magic, non-combative movement, or to target a creature for judgement.

Magic Resistance. The Crow of Judgement has advantage on saving throws against non-radiant spells that require a spell save DC. This does not include area of effect magic, such as Fireball, not does this resistance cover any spellcasting from celestials, clerics, or otherwise radiant creatures.

Innate Spellcasting. The Crow of Judgement's innate spellcasting ability is Wisdom (spell save DC 13). The Crow of Judgement can innately cast the following spells, requiring no material components:

At will: Thaumaturgy
2/day each: Alarm, Bane, Cause Fear, Vicious Mockery
1/day each: Spare the Dying

Beak. Melee Weapon Attack: +1 to hit, reach 5 ft., one target. Hit: 2 (1d4 + 1) piercing damage.

Target for Judgement. If the Crow of Judgement is flying and has line of sight on a target, it can select a creature to specifically circle or land on. The creature must succeed on a DC 15 Dexterity saving throw to shoo the Crow away, or else the Crow will have successfully engaged with the target. The Crow is now exclusively targeting the creature for judgement and berating. The target has disadvantage on Concentration. A targeted creature can attempt to dismiss the Crow, on their turn, with a DC 15 Intimidation check, as a Bonus Action.

Swift Rebuttal. When a creature misses on a melee attack against the Crow of Judgement, it flutters out of reach of the creature and can cast Vicious Mockery, shaming the creature for its failed attack. The Crow of Judgement only gains this reaction if the attacking creature, or any other creature within 60 ft. of the Crow of Judgement understands at least one language the Crow speaks.
