Traits

Spirit-infused Structure

The walled horror is immobile except for its Wall Hop trait. It uses its Charisma instead of its Dexterity to determine its place in the initiative order.

Wall-bound Spirits

The spirits that make up the walled horror are bound to a 10-foot-by-10-foot panel of wall, behind which their original bodies are trapped. The walled horror can move to nearby walls with its Wall Hop trait, but it can never be more than 120 feet away from its bound wall. If its bound wall is damaged while the walled horror is elsewhere, the walled horror takes half the damage dealt to the bound wall. When the walled horror finishes a long rest while inhabiting its bound wall, any damage to the bound wall is repaired.

Wall Hop

As a bonus action, the walled horror can disappear into the wall and reappear on a 10-foot-by-10-foot stone wall or panel of wood that it can see within 30 feet of it. Claw marks briefly appear on the surface of the origin and destination walls when it uses this trait.

Actions

Entomb

The walled horror makes one spectral claw attack against a Medium or smaller creature it is grappling. If the attack hits, the creature is partially entombed in the wall, and the grapple ends. The entombed target is blinded and restrained, and it takes 9 (2d8) psychic damage at the start of each of the walled horror's turns. A walled horror can have only one creature entombed at a time.

A creature, including the entombed target, can take its action to free the entombed target by succeeding on a DC 15 Strength check.

A creature slain while entombed is pulled fully into the wall and can be restored to life only by means of a true resurrection or a wish spell.

Multiattack

The walled horror makes two spectral claw attacks.

Spectral Claw

+7 to hit, reach 10 ft (3 m). Hit: 2d6+4 plus 1d8 psychic damage.

Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 11 (2d6 + 4) slashing damage plus 4 (1d8) psychic damage, and the target is grappled (escape DC 15).

Spectral Scream

+7 to hit, range 60 ft (18.3 m). Hit: 4d8 psychic damage.

Ranged Spell Attack: +7 to hit, range 60 ft., one creature. Hit: 18 (4d8) psychic damage, and the target must succeed on a DC 15 Charisma saving throw or be frightened until the end of its next turn as it is assaulted by images of being buried alive or entombed. While frightened, the creature's speed is reduced to 0.
