Special Traits

  • Mist Form. The devouring mist can occupy another creature’s space and vice versa. In addition, if air can pass through a space, the mist can pass through it without squeezing. The mist moves through water as if it were difficult terrain. The mist can’t use objects in any way that requires hands; it can apply simple force only.
  • Blood Sense. The devouring mist can sense living creatures that have blood or similar vital fluids in a radius of 60 feet.
  • Sunlight Hypersensitivity. The devouring mist takes 20 radiant damage when it starts its turn in sunlight. While in sunlight, the mist has disadvantage on attack rolls and ability checks

Actions

  • Blood Drain. One creature other than a construct or undead that is in the devouring mist’s space must make a DC 16 Constitution saving throw. On a failed save, the target takes 28 (8d6) necrotic damage and its hit point maximum is reduced by an amount equal to the necrotic damage taken. In addition, the mist regains hit points equal to that amount. This reduction to the target’s hit point maximum lasts until the target finishes a long rest. It dies if this effect reduces its hit point maximum to 0. A humanoid slain by this attack rises 24 hours later as a zombie under the mist’s control, unless the humanoid is restored to life or its body is destroyed. The mist can have no more than twelve zombies under its control at one time.

About

This drifting nightmare resembles a cloud of dark-red vapor about 10 feet in diameter.

Devouring mists are undead composed of equal parts blood and malice, wedded together by negative energy. They look for living prey to feed on and torment. When they strike, they surround their enemies and draw their blood from their bodies. Devouring mists are possessed of a malicious cunning. They are quite capable of blending into natural mists so as to take their prey unaware. They may also follow creatures for a time and attack when they are distracted or preoccupied. A devouring mist may stalk its prey over hours or even days, striking again and again, in effect milking them of blood.

Devouring mists do not speak, nor can they be communicated with.
