Life Drain

Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 10 (3d6) necrotic damage and the target must succeed on a DC 10 Constitution saving throw or its hit point maximum is reduced by an amount equal to the damage taken. This reduction lasts until the creature finishes a long rest. The target dies if its hit point maximum is reduced to 0.

Hurl

The specter targets a Medium or smaller creature or an object weighing no more than 150 pounds within 30 feet of it. A creature makes a DC 12 Strength saving throw. On a failure it is hurled up to 30 feet in any direction (including upwards) taking 3 (1d6) damage for every 10 feet it is hurled. An object is launched up to 30 feet in a straight line and a creature in its path makes a DC 12 Dexterity saving throw taking 7 (2d6) bludgeoning damage on a failure. On a success the creature takes no damage and the object keeps flying past it.

Fade

While not in sunlight the specter turns invisible and takes the Hide action. It remains invisible for 1 minute or until it uses Life Drain or takes damage. If the specter takes radiant damage it can't use this action until the end of its next turn.
