  • Ethereal Sight. The guiguai can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.
  • Incorporeal Movement. The guiguai 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.
  • Peachwood Weapons. Guiguai are particularly vulnerable to weapons made from the wood of the peach tree. When the guiguai is hit by a weapon made of peachwood, it takes damage as if the weapon was magical.
  • Sunlight Vulnerability. While in sunlight, the guiguai has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight, and it loses its resistance to nonmagical weapons.


  • Multiattack. The guiguai can make one withering touch attack or two necrotic bolt attacks.
  • Withering Touch. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 17 (4d6 + 3) necrotic damage.
  • Necrotic Bolt. Ranged Weapon Attack: +5 to hit, range 30/120 ft., one target. Hit 10 (2d6 + 3) necrotic damage.
  • Etherealness. The guiguai enters the Ethereal Plane from the Material Plane, or vice versa. It is visible on the Material Plane while it is in the Border Ethereal, and vice versa, yet it can’t affect or be affected by anything on the other plane, with the exception of peachwood weapons.


When creating a guiguai, you must choose how the guiguai manifests. Each guiguai manifests in a way unique to the sinful life it led before it died. A manifestation adds one or more features to the base guiguai or adjusts its current features.

Each guiguai must have at least one manifestation, but it can have more. Increase the guiguai’s challenge rating by 1 for each manifestation you add to it beyond the first manifestation.

In some locations, the walls between the worlds of the living and the dead are thin. For the inhabitants of these areas, it is more important than ever to perform proper burial rites, for the smallest mistake could give rise to a guiguai.

Lifelike Appearance. If a guiguai does not look a living creature in the eye, it is indistinguishable from how it appeared in life. Once the ghost’s gaze meets a living creature’s gaze, its ghostly nature becomes apparent.

Sins of Life. While most ghosts result from the improper burial of a body, guiguai arise due to funeral rites that do not properly atone for the dead individual’s unique sins in life. Restitution to the gods must be made to negate the weight of a person’s sins pulling them back to the world of the living.

Undead Nature. The guiguai doesn’t require air, food, drink, or sleep.
