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. \n'b'  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. \n'b'  Knight . The dullahan is a  mounted combat  expert. In addition, the dullahan can use the mount\xe2\x80\x99s  reaction  to negate a single  melee attack  directed at the mount. Finally, while mounted, the dullahan does not provoke attacks of opportunity. \n'b'  Regeneration . The dullahan regains 5 hit points at the start of its turn. If the dullahan takes radiant damage, this trait doesn\xe2\x80\x99t function at the start of the dullahan\xe2\x80\x99s next turn. The dullahan dies only if it starts its turn with  0 hit points  and doesn\xe2\x80\x99t  regenerate . \n'b'\n'b' ACTIONS \n'b'\n'b'  Multiattack . The dullahan makes two freezing blade attacks, plus one nightmare hooves attack if it is mounted. \n'b'  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. \n'b'  Nightmare Hooves (only if Mounted) .  Melee Weapon Attack : +11 to hit, reach 5 ft., one target.  Hit : 13 (2d8 + 4) bludgeoning damage plus 7 (2d6) fire damage. \n'b'  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. \n'b'\n'b' REACTIONS \n'b'\n'b'  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. \n'b'\n'b' LEGENDARY ACTIONS \n'b' 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\xe2\x80\x99s turn. The dullahan regains spent legendary actions at the start of its turn. \n'b'\n'b'  Death\xe2\x80\x99s Calling (1/Day) . A dullahan may place death\xe2\x80\x99s 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\xe2\x80\x99s 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 is maximized. Finally, the victim automatically fails all death saving throws to stabilize while dying. Death\xe2\x80\x99s calling automatically recharges if the target makes its saving throw. \n'b'  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. \n'b'  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. \n'b'\n'b' ABOUT \n'b' Clad in ragged black robes and tarnished armor, this grim, headless rider is surrounded by an aura of menace. Terrifying reapers of souls, dullahans are created by powerful fiends from the souls of particularly cruel generals, watch-captains, or other military commanders. Sent back from the pits of Hell to sow terror and harvest new souls, dullahans return to the towns or villages they lived in as mortals. While their favored victims are evil men and women (or their living descendants) whose souls are destined for Hell, the dullahans have no qualms about adding innocents to their lists of victims.'
