Ancient Obsidian Dragon

The more nefarious of the dragons, the black dragons believe the weak should serve the strong, and that death is a sacred tool meant to give your will and power to the righteous who truly deserve it.
The most feared type of dragon among the mundane races, their history of destruction is well known and documented. As is the pleasure they derive from their machiavellian planning and dark schemings.

Claw. Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 20 (2d10 + 10) slashing damage.
Necrotic Breath (Recharge 5–6). The dragon exhales darkness in a 90-foot cone. Each creature in that area must make a DC 24 Dexterity saving throw, taking 91 (26d6) necrotic damage on a failed save, or half as much damage on a successful one.
Reaction
Necrotic trap. When a zombie dies within sight of the dragon, he can unleash the necrotic magic trapped within the zombie. Any creature within 20ft of the zombie must succeed on a DC 24 Constitution saving throw or take 3d10 necrotic damage.
Villain Actions
The dragon can take 3 villain actions, he can take each action once during an encounter after an enemy creature’s turn. He can take these actions in any order but can only use one per round.
Action 1: Weakening Presence. Each creature of the dragon's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 21 Wisdom saving throw or only deal half damage with weapon attacks and spells. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Action 2: Power Word: Kill (9th Level Spell). The dragon utters a word of draconic power that can compel one creature within 60ft to die instantly. If the chosen creature has 100 hit points or fewer, it dies. Otherwise, the spell has no effect.
Action 3: Maddening Darkness (8th Level spell). Magical darkness spreads in a 60-foot-radius sphere around the dragon until the spell ends. The darkness spreads around corners. A creature with darkvision can’t see through this darkness. Nonmagical light, as well as light created by spells of 8th level or lower, can't illuminate the area. Shrieks, gibbering, and mad laughter can be heard within the sphere. Whenever a creature starts its turn in the sphere, it must make a Wisdom saving throw, taking 8d8 psychic damage on a failed save, or half as much damage on a successful one.
