Incorporeal Movement. The wraith can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Sunlight Sensitivity. While in sunlight, the wraith has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight. Additionally, its Life Drain has no effect while in direct sunlight. 

Movement. At the start of the wraith's turn, the wraith can choose to forgo a reaction to add 30 ft. to its movement speed until the start of its next turn. 

Create Specter (Recharge 6). The wraith targets a humanoid within 10 feet of it that has been dead for no longer than 1 minute and died violently. The target's spirit rises as a specter in the space of its corpse or in the nearest unoccupied space. The specter is under the wraith's control. The wraith can have no more than seven specters under its control at one time.

Invisibility. The wraith and its gear become invisible until it attacks or casts a spell, or until its concentration ends (as if concentrating on a spell).

Chill Touch. Melee Spell Attack: +5 to hit, reach 5 ft., one creature. Hit: 21 (6d6) necrotic damage. The wraith's touch also has a chilling effect. If the target is a creature, it must make a DC 14 Constitution saving throw or have disadvantage on attack rolls against the wraith until the end of the wraith's next turn.

Life Drain.The wraith targets one creature it can see within 30 feet of it. The target must make a DC 14 Constitution saving throw, taking 21 (6d6) necrotic damage on a failed save, or half as much damage on a successful one. The targets 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. A humanoid slain by this attack rises 24 hours later as a wraith under the wraith's control, unless the humanoid is restored to life or its body is destroyed.
