Annihilating Aura. Any creature that starts its turn within 30 feet of the nightwalker must succeed on a DC 21 Constitution saving throw or take 14 4d6 necrotic damage and grant the nightwalker advantage on attack rolls against it until the start of the creature's next turn. Undead are immune to this aura.
Life Eater. A creature reduced to 0 hit points from damage dealt by the nightwalker dies and can't be revived by any means short of a wish spell.

Actions

Multiattack. The nightwalker uses Enervating Focus twice, or it uses Enervating Focus and Finger of Doom, if available.
Enervating Focus. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 28 5d8+6 necrotic damage. The target must succeed on a DC 21 Constitution saving throw or its hit point maximum is reduced by an amount equal to the necrotic damage taken. This reduction lasts until the target finishes a long rest.
Finger of Doom (Recharge 6). The nightwalker points at one creature it can see within 300 feet of it. The target must succeed on a DC 21 Wisdom saving throw or take 26 4d12 necrotic damage and become frightened until the end of the nightwalker's next turn. While frightened in this way, the creature is also paralyzed. If a target's saving throw is successful, the target is immune to the nightwalker's Finger of Doom for the next 24 hours.

Nightwalkers were the shades of extremely strong-willed and evil mortals whose ancient and unyielding will and malice allowed them to hold their corporeal shape. A nightwalker's body looked as if it was made of shadow-stuff, with a vaguely humanoid form. They were about the size of a house, but were usually no taller than 20 feet (six meters), and their bodies were smooth and hairless.
