Traits
Legendary Resistance (3/Day). If Nebiros fails a saving throw, he can choose to succeed instead.
Magic Resistance. Nebiros has advantage on saving throws against spells and other magical effects.
Magic Weapons. Nebiros’s weapon attacks are magical.
Abyssal Hellfire. A creature that touches Nebiros or hits him with a melee attack while within 10 feet of him takes 10 (3d6) fire damage. When Nebiros deals fire damage, it ignores resistance to fire damage.
Black, Light-Absorbing Feathers. While in dim light or darkness, Nebiros can take the Hide action as a bonus action. If he is motionless in such light, he is invisible.
Royal Necromancer. When a Medium or smaller creature dies within 120 feet of Nebiros, he can use his reaction to raise it as a zombie under his control. The zombie acts on the same initiative count as Nebiros but after his turn and lasts for 1 hour or until it or Nebiros is destroyed.
Three-Headed. Nebiros has advantage on Wisdom (Perception) checks and on saving throws against being blinded, deafened, stunned, or knocked unconscious.
Actions
Multiattack. Nebiros makes four attacks: three with his Beaks and one with his Tail.
Beak. Melee Weapon Attack: +16 to hit, reach 15 ft., one target. Hit: 31 (4d10 + 9) slashing damage plus 13 (3d8) necrotic damage.
Tail. Melee Weapon Attack: +16 to hit, reach 20 ft., one target. Hit: 27 (4d8 + 9) bludgeoning damage. The target must succeed on a DC 24 Constitution saving throw or be poisoned for 1 minute. While poisoned in this way, the target is also paralyzed. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Sulfuric Hellfire (Recharge 5–6). Nebiros exhales hellish flames in a 60-foot line that is 10 feet wide. Each creature in the line must make a DC 24 Dexterity saving throw, taking 77 (14d10) fire damage on a failed save, or half as much damage on a successful one. A creature that fails by 5 or more is frightened of Nebiros until the end of its next turn.
Inferno Halberd (Humanoid Form Only). Melee Weapon Attack: +16 to hit, reach 10 ft., one target. Hit: 35 (4d12 + 9) slashing damage plus 18 (4d8) fire damage, and the target must succeed on a DC 24 Constitution saving throw or be paralyzed until the end of its next turn.
Teleport. Nebiros magically teleports, along with any equipment he is wearing or carrying, up to 120 feet to an unoccupied space he can see.
Bonus Actions
Leap. Nebiros jumps up to his walking speed without provoking opportunity attacks. Each creature within 5 feet of the space where he lands must succeed on a DC 24 Dexterity saving throw or take 14 (4d6) fire damage and be knocked prone.
Reactions
Necrotic Spittle. When a creature within 30 feet of Nebiros hits him with a ranged attack, Nebiros spits corrosive ichor at it. The attacker must succeed on a DC 24 Dexterity saving throw or take 21 (6d6) necrotic damage and have its speed reduced by 10 feet until the end of its next turn.
Legendary Actions
Nebiros can take 3 legendary actions, choosing from the options below. Only one legendary action can be used at a time and only at the end of another creature’s turn. Nebiros regains spent legendary actions at the start of his turn.
Beak Attack. Nebiros makes one Beak attack.
Command the Dead. Up to three undead of Nebiros’s choice that he can see within 60 feet use their reactions to move up to their speed and make one attack each.
Flash of Wrath (Costs 2 Actions). Each creature of Nebiros’s choice within 30 feet must make a DC 24 Wisdom saving throw or take 22 (4d10) psychic damage and be frightened of Nebiros until the end of its next turn.
Winged Burst (Costs 3 Actions). Nebiros beats his wings, emitting scalding winds. Each creature within 20 feet must succeed on a DC 24 Dexterity saving throw or take 26 (4d8) fire damage and be pushed 15 feet away from Nebiros and knocked prone. Nebiros can then fly up to half his flying speed without provoking opportunity attacks.
Lore
A wrathful three-headed rooster who necromances, corrupts animals, foretells, and harms at will.
The entity known as Nebiros is mentioned in European grimoires of the period.
In ancient legends and demonological registers, Nebiros is chiefly addressed by the titles Royal Necromancer, Black Count, and Lord of Wrath. His conceptual domains are anger, hatred, revenge, and war; he presides over the destructive emotions that give rise to conflict and tragedy.
