Innate Spellcasting.
The trickster demon’s spellcasting ability is Charisma (spell save DC 15).
The trickster demon can innately cast the following spells, requiring no material components:
At will: charm person, mage hand, minor illusion
2/day each: alter self, mirror image, sleep
1/day each: major image, mislead
Magic Resistance. The trickster demon has advantage on saving throws against spells and other magical effects.
Shadow Stealth. While in dim light or darkness, the trickster demon can take the Hide action as a bonus action.

Actions

Multiattack. The trickster demon makes two Disfiguring Touch attacks.
Disfiguring Touch. Melee Weapon Attack: +8 to hit, reach 5 ft., creature. Hit: 17 (4d6 + 3) necrotic damage, and the target’s Charisma score is reduced by 1d4. The target is incapacitated if this reduces its Charisma to 0. Otherwise, the reduction lasts until the target finishes a short or long rest.
Slashing Attack - Melee Weapon Attack +8, reach 5ft. Hit 3d6+4.  The demon lashes out with it's larger claw and tries to tear the flesh from the targets face. 

Reactions

Clumsy Advance.
When a creature the trickster demon can see moves within 10 feet of the demon, the creature must succeed on a DC 15 Dexterity saving throw or be knocked prone as it trips over its own feet, over a sudden flaw in the ground where it walks, or experiences some other clumsy stumble as it moves toward the demon.

This type of demon is a trickster demon who uses the veils between planes to traverse into the material plane.  During the season of autumn near the end of Lothor the barriers between it's plane and the material plane weaken to the point where the demon can slip through shadows.  Once in the Material plane it loves to create chaos in a town or city using dangerous tricks to amuse itself.  Often it likes to replace a child in a household and attempt to torture the family for years if it can get away with it.  

Mental characteristics

Personal history

These particular trickster demons cross between planes when the barriers weaken.  Though in their true form they are spider like and quite alien looking, they use their shape shifting powers to hide when in the Material plane.  Once inserted into a settlement in the material plane they target a family or group and then attempt to take the place of a member of that group.  Usually a child or elderly person because they are easier to dispose of and replicate.  Once inserted they wreak havoc on the settlement as long as possible before moving on.  It is suspected that instead of feeding on flesh or bone, these creatures feed on psychic emotions like fear and anxiety.
