Specter A5E

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.

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.

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.
