Special Traits

  • Death Curse. If a mordnaissant dies, it releases a death curse on all creatures within 30 feet of it. Those creatures must make a DC 15 Wisdom saving throw. On a failed saving throw, the creature cannot regain hit points from spending hit dice and it has disadvantage on all saving throws for 24 hours. A remove curse or greater magic is necessary to end this curse early.
  • Shield of Agony. The mordnaissant’s Armor Class includes its Charisma modifier.


  • Lash of Fury. Ranged Spell Attack: +5 to hit, range 30 ft., one target. Hit: 24 (5d8 + 2) necrotic damage and the target must make a DC 14 Constitution saving throw or lose 1d4 points of Intelligence. The target becomes incapacitated if this reduces its Intelligence to 0. Otherwise, the reduction lasts until the target finishes a long rest.
  • Pain Wail. The mordnaissant releases a wail. Creatures within 20 feet that can hear the mordnaissant must make a DC 14 Wisdom saving throw. On a failed saving throw, the target is stunned until the end of its next turn.


Floating before you is a horrid, shriveled human fetus nested within a translucent sphere of dark energy. Its jet-black eyes glitter with intensity as it twitches and spasms slightly, as if in great pain.

Occasionally when a woman with child dies violently in a place infused with unholy or negative energies, the unborn child within her does not perish, but instead continues to grow, vitalized by dark power, until it is capable of clawing its way free from its dead mother. This horrible creature, known as a mordnaissant, lives an existence of eternal pain, loneliness, and suffering and is relieved only by its ability to inflict harm on those around it. Mordnaissants avoid bright light if they can, though they suffer no ill effects from it.
