Death Gaze. When a creature that can see the Vilandra’s eyes starts its turn within 30 feet of Vilndra, Vilandra can force it to make a DC 23 Constitution saving throw if Vilandra isn’t incapacitated and can see the creature. If the saving throw fails by 5 or more, the creature is reduced to 0 hit points, unless it is immune to the frightened condition. Otherwise, a creature takes 33 (6d10) psychic damage on a failed save.

Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it has disadvantage on attack rolls against Vilandra until the start of its next turn. If the creature looks at Vilandra in the meantime, it must immediately make the saving throw.

Freedom of Movement. Vilandra ignores difficult terrain, and magical effects can't reduce her speed or cause it to be restrained.

Incorporeal Movement. Vilandra can move through other creatures and objects as if they were difficult terrain. She takes 5 (1d10) force damage if she ends its turn inside and object.

Legendary Resistance (5/Day). If Vilandra fails a saving throw, she can choose to succeed instead.

Magic Resistance. Vilandra has advantage on saving throws against spells and other magical effects.

Spectral Defense. Vilandra's AC includes her Constitution modifier.

Sunlight Sensitivity. While in sunlight, the dracowraith has disadvantage onattack rolls, as well as on Wisdom (Perception) checks that rely on sight.

Wisps of Annihilation. A creature that touches Vilandra or hits her with a melee attack while within 5 feet of her takes 5 necrotic damage and has its hit point maximum reduced by an amount equal to the damage taken. If Vilandra takes radiant damage, the wisps burst outwards and each creature within 10 feet of her takes 20 necrotic damage and has its hit point maximum 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.

Multiattack. Vilandra can use her Cry of the Open Grave. She then makes three attacks: one with her bite and two with her claws.

Spectral Bite. Melee Weapon Attack: +19 to hit, reach 15 ft., one target. Hit: 61 (10d10 + 6) necrotic damage. If the target is a living creature, Vilandra regains hit points equal to the damage done.

Spectral Claw. Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 41 (10d6 + 6) necrotic damage. If the target is a creature, it must succeed on a DC 21 Constitution saving throw or its 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.

Spectral Tail. Melee Weapon Attack: +19 to hit, reach 20 ft., one target. Hit: 33 (6d8 + 6) necrotic damage. If the target is a creature, it must succeed on a DC 21 Constitution saving throw or its 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.

Cry of the Open Grave. Vilandra lets forth a horrible, mind-shattering screech. Each living creature within 120 feet of Vilandra that can hear her must make a DC 21 Wisdom saving throw. On a failed save, a creature takes 45 (10d8) psychic damage and becomes frightened for 1 minute. On a successful save, a creature takes half the psychic damage and doesn’t become frightened. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature’s saving throw is successful or the effect ends for it, the creature is immune to the frightening effect of Vilandra's Cry of the Open Grave for the next 24 hours.

In addition, all humanoids within range of the screech that have been dead for no longer than 1 minute and died violently are corrupted by undeath. The spirit’s of any such humanoids rise as wraiths in the space of their corpses or in the nearest unoccupied space. The wraiths are under Vilandra's control. Vilandra can have no more than twelve wraiths under its control at one time.

Necrotic Breath (Recharge 5-6). Vilandra exhales negative energy in a 90-foot cone. Each creature in that area must make a DC 21 Dexterity saving throw, taking 112 (32d6) necrotic damage on a failed save, or half as much damage on a successful one. A humanoid reduced to 0 hit points by this damage dies.

Vilandra can take 5 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. Vilandra regains spent legendary actions at the start of her turn.

Detect. Vilandra makes a Wisdom (Perception) check.

Move (Costs 2 Actions). Vilandra moves up to her speed.

Tail Attack. Vilandra makes a tail attack.

Wing Attack (Costs 2 Actions). Vilandra beats her spectral wings. Each creature within 15 feet of Vilandra must succeed on a DC 21 Dexterity saving throw or take 20 (4d6 + 6) necrotic damage and have its movement speed halved until the end of its next turn.
