  • Animate Servants (Recharge 6). The necrolord conjures 1d4 vampires or a mummy lord in an unoccupied square within 30 feet.
  • Colossal Tail. Melee Weapon Attack: +18 to hit, reach 150 ft., multiple targets more than 30 feet away from Níðhöggr (150-foot cone centered on one target; roll separately for each creature and object in the area). Hit: 42 (5d12+10) bludgeoning damage and the target makes a DC 26 Strength saving throw or is knocked prone.
  • Necroscythe. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 18 (3d6+8) magical slashing damage plus 14 (4d6) necrotic damage and 14 (4d6) psychic damage. If the target is a creature, its hit point maximum is reduced by an amount equal to the necrotic and psychic damage taken. The target dies if this attack reduces its hit point maximum to 0. The reduction lasts until removed by the greater restoration spell or other magic.


The necrolord can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The necrolord regains spent legendary actions at the start of its turn.

  • Cantrip. The necrolord casts a cantrip.
  • Necroscythe (Costs 2 Actions). The necrolord makes one necroscythe attack.
  • Disrupt Life (Costs 3 Actions). Each non-undead creature within 20 feet of the necrolord must make a DC 20 Constitution saving throw against this magic, taking 21 (6d6) necrotic damage on a failed save, or half as much damage on a successful one.


There is only the necrolord. The master of undeath is among the oldest creatures in existence and like a stone fixed against the current of time. It fiercely guards its ancient knowledge however and long ago became obsessed with its hunger to know not just more but all, that craving all that remains of the mortal it once was.
