  • Frightful Presence. When the dullahan makes an attack all creatures who can see the dullahan become frightened on a failed DC 18 Wisdom saving throw for 1 minute. Creatures who successfully save are immune to this effect for 24 hours.
  • Infernal Identification. As a bonus action, a dullahan can consult the powers of Hell to supernaturally discern the name of any living creature born on the Material Plane.
  • Knight. The dullahan is a mounted combat expert. When mounted the dullahan’s mount may make one attack from its listed options as part of the dullahan’s Multiattack: In addition, the dullahan can use the mount’s reaction to negate a single melee attack directed at the mount. Finally, while mounted, the dullahan does not provoke attacks of opportunity. Regeneration. The dullahan regains 5 hit points at the start of its turn. If the dullahan takes radiant damage, this trait doesn’t function at the start of the dullahan’s next turn. The dullahan dies only if it starts its turn with 0 hit points and doesn’t regenerate.


  • Multiattack. The dullahan makes two freezing blade attacks.
  • Freezing Blade. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit. 10 (1d8 + 6) slashing damage and 3 (2d6) cold damage. A creature that takes cold damage from this attack is slowed (as the spell) on a failed DC 18 Constitution saving throw. The affected creature may repeat the saving throw at the start of its turn to end this effect.
  • Summon Nightmare (Recharges after a Short or Long Rest). A dullahan can summon a nightmare to serve him. The nightmare remains until it is slain or the dullahan dismisses it. He can only have one such nightmare in his service at a time.


  • Parry. The dullahan adds 2 to its AC against one melee attack that would hit it. To do so, the dullahan must see the attacker and be wielding a melee weapon.


The dullahan can take 2 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 dullahan regains spent legendary actions at the start of its turn.

  • Death’s Calling (1/day). A dullahan may place death’s calling on a target within 60 feet if the target fails a DC 18 Wisdom saving throw. If the dullahan knows and speaks the target’s name, the target has disadvantage on the save. Cursed creatures have disadvantage on attack rolls against the dullahan. For the next 24 hours (or until the dullahan is slain), all critical hit damage against the target are maximized. Finally, the victim automatically fails all death saving throws to stabilize while dying. Death’s calling automatically recharges if the target makes its saving throw.
  • Icy Gaze. A dullahan fixes its dreadful gaze on a single creature within 60 feet. The target must succeed on a DC 18 Wisdom save or become paralyzed. Even if the saving throw succeeds the target is still shaken and has disadvantage on attacks, saving throws and ability checks until the end of its next turn.
  • Infernal Alacrity. A dullahan gains an effect identical to a haste spell for 1 minute. If the dullahan is mounted when it invokes this ability, its mount is also hasted.


Clad in ragged black robes and tarnished armor, this grim, headless rider is surrounded by an aura of menace.
