Special Traits

  • Incorporeal Movement. The demonic mist can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.
  • Innate Spellcasting. A demonic mist’s spellcasting ability is Charisma (spell save DC 13, +5 to hit with spell attacks), and requires no material components for the following spells:
  • Vulnerability to Wind. The demonic mist has disadvantage on saving throws against wind and wind-like effects (gust of wind, etc.).


  • Demonic Touch. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 25 (6d6 + 4) necrotic damage.
  • Psychic Crush (Recharge 5-6). The demonic mist attempts to crush the mind of a single creature it can see within 30 feet. The target must make a successful DC 15 Wisdom saving throw or take 14 (4d6) psychic damage and be frightened for 1 minute.


This cloud of sickly green mist seems to move as if it were alive.

Some scholars and sages believe a demonic mist is the incomplete manifestation of a demon on the Material Plane. Others conjecture it is a representation of chaos unleashed by the denizens of the Abyss. Whatever the true nature of its origin, a demonic mist is a creature wholly chaotic and evil. When encountered on the Material Plane it is most often in areas of consecrated ground such as graveyards, temples, and holy sites. In their native environment, demonic mists are found haunting the most putrid and disgusting of the Abyssal planes. Those planes covered with oozes, mires, fens, and swamps are favored by these creatures. Demonic mists have voracious appetites and always seem to be on the hunt. They are carnivorous creatures devouring just about anything they came across.

Once a demonic mist slays its prey, it moves over the body and rapidly digests it, draining blood and body fluids, and leaving nothing more than a dried husk.

A demonic mist’s semi-solid body is composed of a strange, sickly green and ever-shifting mist. It can change its color to a semi-translucent whitish smoke, thereby blending in and hiding in areas of normal fog and mist. When hiding in this way, a demonic mist seeks to quickly close ground with its target and attack from ambush, unleashing its psychic crush and enervating attacks at the closest and strongest opponents.

Demonic mists are often found in the employ of clerics dedicated to the demonic lords (particularly Tsathogga and Jubilex), serving as temple guards or assassins.
