Chaotic Evil. The demon radiates a Chaotic and Evil aura. 

Incorporeal. The demon can move through creatures and objects. It takes 3 (1d6) force damage if it ends its turn inside an object. 

Light Sensitivity. While in bright light, the demon has disadvantage on attack rolls, as well as on Perception checks that rely on sight.


Darken Light. The demon magically targets a nonmagical flame or an area of magical light created by a 2nd-level or lower spell slot within 60 feet. Any area of bright light created by the light source instead casts dim light for 10 minutes.

Replace Shadow. The demon targets a humanoid within 5 feet that is in dim light and can’t see the demon. The target makes a DC 13 Constitution saving throw . On a success, the target is aware of the demon. On a failure, the target is unaware of the demon, the target no longer casts a natural shadow, and the demon magically takes on the shape of the target’s shadow, appearing indistinguishable from a natural shadow except when it attacks. The demon shares the target’s space and moves with the target. When the demon is dealt damage while sharing the target’s space, it takes half the damage (rounded down) and the other half is dealt to the target. The effect ends when the target drops to 0 hit points, the demon no longer shares the target’s space, the demon or target is affected by dispel evil and good or a similar effect, or the demon begins its turn in an area of sunlight.

Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 14 (2d10 + 3) cold damage.


Shadow Sneak. The demon takes the Hide action even if obscured only by dim light or darkness.


The shadow demon uses Darken Light to create areas of dim light and Shadow Sneak to hide in plain sight. It then uses Replace Shadow. Once it has done so, it may use its claws immediately, or it may travel with its victim for some time before it attacks. If it’s unable to use Replace Shadow, it tries to attack from hiding. It flees if dealt radiant damage.

Legends and Lore

With an Arcana or Religion check, characters can learn the following:

DC 10 Demons are fiends spawned from the Abyss. They are creatures of pure chaos: even the most intelligent demon can’t be reasoned with.

DC 15 Poison can’t adversely affect a demon’s alien physiology. They shrug off much of the damage caused by cold, fire, lightning, and mundane weapons.

DC 20 The most powerful demons are even more resilient. They entirely ignore the effects of many magic spells.


Appearing as gaunt, winged figures made of semi-solid darkness, shadow demons are often mistaken for specters or other undead. In fact, they are what becomes of a more powerful demon when its essence is prevented from reforming in the Abyss. Shadow demons hate bright light and can magically cause torches and other light sources to dim on command. More frightening, however, is their ability to meld with another creature’s shadow, literally following in the unwitting victim’s footsteps until the chance to strike presents itself.
